Control panel assembly to your schematic
Control panel assembly starts from your documentation: with the electrical schematic and, if there is one, the bill of materials, Justicia Marin reviews the requirements, closes the part numbers and coordinates the execution with a specialised manufacturer in the network. You receive the assembly mounted, wired, identified and checked against the schematic.
What it includes
What control panel assembly includes
Control panel assembly consists of laying out and connecting the components defined in the schematic on a mounting plate or an enclosure, and identifying conductors and terminals according to that same documentation. An assembly prepared this way saves hours of work on the machine or on site, because it arrives ready to connect without reinterpreting anything. The scope is agreed before the order: which part numbers are respected, what is wired, what is identified and what is checked before delivery.
- Review of the electrical schematic and the bill of materials
- Layout of components on a plate, DIN rail or enclosure
- Internal wiring with cross-section and colour according to the schematic
- Identification of conductors, terminals and components
Types of assembly
Common control panel configurations
In practice, control panel, electrical panel and electrical cabinet usually name configurations of the same supply: the size, the enclosure and the application change, not the way of ordering it. For industrial control panels the scope is adjusted to the project, from an equipped plate to the complete cabinet. Not every manufacturer in the network covers every configuration, so this is confirmed before quoting.
Mounting plate for control panels
Components laid out and wired on a plate, ready to be fitted into the enclosure at destination. This is the usual scope when the panel is closed at the point of installation.
Machine panel
Assembly associated with a specific machine, with the internal wiring prepared and the terminals arranged for the field connections indicated in the schematic.
Control and automation panel
Automation and control panels with PLC, operating and signalling elements according to the schematic supplied. Programming and commissioning are outside the scope.
Custom electrical cabinet
When the assembly grows, the assembly of industrial electrical cabinets is carried out on the chosen enclosure, with the layout and identification agreed for the project. It is the usual configuration of control cabinets delivered assembled and ready to connect at destination.
Starting data and criteria
What to define before requesting a quote for control panels
The quote is prepared on the information available and sets out in writing the scope the selected manufacturer can take on.
- Electrical schematic and current revision
- Planned enclosure or plate, and layout if already defined
- Bill of materials or part numbers that must be respected
- Identification required on conductors, terminals and components
- Documentation that must accompany the delivery
- Estimated quantity and expected repeat orders
- Target delivery date and packaging suitable for the planned transport
Decision points
What must be settled before assembling the control panels
These three decisions are the ones that avoid rebuilding a panel. Once fixed, the configuration can be ordered again without reinterpreting it.
Schematic review
The schematic is checked against the bill of materials and any doubts are resolved before ordering anything. What remains open at this stage ends up being decided during assembly, which is exactly what should be avoided.
Documented material and equivalents
The availability of each part number is confirmed and, where the lead time advises it, equivalents are proposed in writing. No substitution is applied without prior approval.
Identification and delivery documentation
It is agreed what is identified inside the panel and which documentation accompanies the supply, so that commissioning does not depend on who assembled it.
How we coordinate the supply
From schematic to delivered control panels
The more complete the schematic, the fewer open decisions and the lower the risk of deviation.
Documentation and review
We receive the electrical schematic and, if there is one, the bill of materials. We review the requirements and set out the scope in writing before quoting.
Material and equivalents
We confirm the availability of each part number and propose documented equivalents where the lead time advises it.
Assembly, wiring and identification
The specialised manufacturer lays out the components, carries out the internal wiring and identifies conductors, terminals and components according to the schematic.
Checking and delivery
The correspondence of the assembly with the schematic is checked according to the agreed scope and it is delivered with the agreed documentation. If the project repeats, the same configuration is kept.
Assembly coordination
Control panel assembly coordinated with the manufacturer
Justicia Marin does not physically manufacture or assemble the panels or cabinets: the assembly is carried out by a control panel and electrical cabinet manufacturer in the network. As a B2B technical distributor it reviews the requirements, compares manufacturers, closes the material and coordinates quote and supply. That split is what allows you to deal with product, lead time and documentation through a single point of contact.
We start from your documentation
The starting point is your electrical schematic and, if there is one, the bill of materials with the part numbers you want respected. When the assembly needs harnesses prepared separately, they can be supplied as build-to-print cable assemblies and arrive ready to connect.
What we coordinate
Material — part numbers, availability and documented equivalents
Assembly — layout on a plate, rail or enclosure
Wiring — cross-section and colour according to the schematic
Identification — conductors, terminals and components
Checking — correspondence with the schematic, according to the agreed scope
From validated configuration to recurring supply
Once a configuration is validated, control panel assembly and wiring stop being renegotiated on every order: the same revision, the same material and the same identification are kept as long as the project does not change.
Justicia Marin coordinates requirements, material and manufacturer; the physical assembly and wiring are carried out by the specialised manufacturer according to the agreed scope.

What this service actually covers
Control panel assembly is carried out by a manufacturer in the network with the capacity for that type of assembly; Justicia Marin reviews the requirements and coordinates the material, the assembly and the prior check. We have no workshop or engineering office of our own: we do not design the panel, we do not carry out on-site installation, commissioning at the plant or legalisation of installations, and we issue no certificates of our own. The documentation available is that of the material manufacturer and of the manufacturer that carries out the assembly.
Questions before the quote
Control panel assembly: frequently asked questions
- Is Justicia Marin a panel builder?
- No. Justicia Marin is a technical B2B distributor. We review your schematic and bill of materials, supply and coordinate material, harnesses and cable assemblies, and have the panel built by a panel manufacturer that we select for the project. You work with one point of contact; the physical control panel assembly takes place at that manufacturer, not in a workshop of our own.
- What do you need for a control panel assembly quote?
- The electrical schematic with the current revision, the bill of materials with the part numbers that must be kept, the planned enclosure or mounting plate, the required marking of conductors and terminals, the quantity and the target delivery date. The more complete the schematic, the fewer decisions have to be taken during assembly and the more precise the quote.
- Do you also design or program the control panel?
- No. The design of the panel and the electrical schematic come from the customer or its engineering partner. We do not offer PLC programming, commissioning or on-site installation. We coordinate material, assembly, wiring and marking according to the schematic supplied, as agreed in writing beforehand.
- Which standards apply to building a control panel?
- For the electrical equipment of machines, IEC 60204-1 is the usual reference, and for low-voltage switchgear assemblies the EN 61439 series. Which requirements apply to your panel is determined by the project: state them in the specification, and the quote will show what the selected panel manufacturer can document.
- Can separate harnesses for the panel be supplied on their own?
- Yes. Harnesses or interconnecting cables prepared outside the panel can be supplied as build-to-print cable assemblies: cut to length, finished and marked, ready to connect. This way panel and external cabling fit together, with one point of contact for both deliveries.
- What happens if a component in the bill of materials is not available?
- We propose a documented alternative with the relevant characteristics and the consequences for layout or wiring. Nothing is replaced without your prior written approval. Once approved, the change is recorded in the configuration, so that a later panel is built with the same material.
- How is the panel checked before delivery?
- The panel manufacturer checks, within the agreed scope, that the panel matches the schematic: placement, wiring, cross-sections, colours and marking, possibly supplemented by agreed electrical checks. Justicia Marin coordinates that scope and reviews the documentation; commissioning and the final check in the installation remain with the customer.
