1. Check visually inspect the terminal
2. Check that all items are included in accordance with the delivery documen
3. Check for transport damages
4. Check no objects or free parts could be inside the panel
5. Check the door is correctly closed and locked
6. check Storage room must have an adequate temperature and low humidity value  (If you want to store)
7. Check the contact between the electrical panel and aggressive contaminating substances that could prejudice functionality and electrical security
8. Check the panel power supply must be on a dedicated line, and must be placed a device suitable for protection against indirect contacts
9. Ensure that do not fit power supply wiring and signal wiring  (probes/sensors and digital inputs) in the same race ways or ducts
10. Ensure that do not use multi-polar cables in which there are wires connected to inductive/power loads or signaling wires (e.g. probes/sensors and digital inputs)
11. Check to minimize the length of connect or wires so that wiring does not twist into a spiral shape as this could have negative effects on the electronics
12. Make sure that when it is necessary to make a probe/sensor extension, the wires must have a cross-section of at least 1mm²‍
13. Check the control panel fixed properly
14. Check the cold room temperature displaying correctly
15. Check the unit control activation/deactivation
16. Check the unit alarm working properly
17. Ensure the LED indicators and large display, illustrate system status
18. Ensure that defrost operation condition
19. Make sure that cold room light ON/OFF correctly
20. Check the insulation of connecting wires
21. Ensure that during maintenance, electrical panel must be without power
22. Ensure that authorized staff only do the maintenance work
23. Check the tools must be correctly cleaned and greased during maintenance
24. Check clearance of MCB's & MCCB’s
25. Check for any over loading
26. Check voltage at lamp
27. Make sure that all wiring is properly connected and routed away from heat sources, electromagnetic devices, and moving components
28. Check proper relay operation
29. Check the permanent labels affixed
30. Ensure that units/equipment accessible for maintenance/replacement
31. Check the fuses installed and labeling of wire done correctly
32. Make sure that all electrical connections are tight
33. Verify the proper grounding installed for components and unit
34. Check the unit placed in safe and operatable
35. Check the power supply flow into the circuit as per standard
