Electrical & Control Parts
Cabinet and control components — inspected and replaced by qualified electrical personnel per the machine manual's lockout procedures.
Typical Components
The exact configuration depends on your machine model. Your spare parts documentation — issued per machine — lists the qualified items for your serial number.
| Component | Role in the system | Condition to watch |
|---|---|---|
| Fuses & protection devices | Protect circuits | Investigate trip causes — never just reset |
| Contactors & relays | Switch loads | Contact condition — qualified personnel |
| Power supplies | Provide control voltage | Output stability |
| Terminal blocks, cables & connectors | Distribute power and signals | Loose terminals, cable damage |
| Pushbuttons, E-stops & lamps | Operator interface and safety | Function test per manual |
| Cabinet fans & filters | Keep the cabinet cool and clean | Filter saturation |
Condition & Replacement
Qualified personnel — per your machine manual.
- Electrical inspection is part of the monthly routine, performed by qualified personnel under lockout.
- A tripped protective device is a symptom — find the cause before replacing or resetting anything.
- Safety components (E-stops, guards, interlocks) are function-tested per the manual, never bypassed.
Drives, PLCs and safety controllers are serviced per Path Pack documentation — request technical support rather than self-servicing these components. Do not open control cabinets without authorization. Related troubleshooting: Machine Will Not Start and HMI Errors.
Identifying an Electrical Part
Type plates and part numbers matter.
- Machine model and serial number
- Component type plate / part number, photographed
- Position in the cabinet or machine section
See Before Requesting a Part for the full checklist.
