Inspecting the PDB
Commissioning mechanical performance
1. Switch on and off all circuit breakers five times. Ensure that they can be switched on and off smoothly.
2. Check that all bolts are secured for cables. Tighten the bolts that are not properly secured.
3. Check that screws at the ground point are secured. Tighten the screws that are not properly secured.
Testing insulation performance
1. Switch off the SPD standby circuit breaker (QF2).
2. Check that the insulation resistance between the L terminal and the PE terminal on the PDB is greater
than or equal to 2 MΩ.
3. Check that the insulation resistance between the N terminal and the PE terminal on the PDB is
greater than or equal to 2 MΩ.
Inspecting the uninterruptible power system (UPS)
Commissioning mechanical performance
1. Switch on and off all circuit breakers five times. Ensure that they can be switched on and off smoothly.
2. Check that all bolts are secured for cables. Tighten the bolts that are not properly secured.
3. Check that battery cables are correctly connected to battery terminals.
4. Check that screws at the ground point are secured. Tighten the screws that are not properly secured.
5. Check that the voltage between the mains input neutral wire and the ground cable is less than 5 V AC.
Inspecting the battery pack
Commissioning mechanical performance
1. Switch on and off all circuit breakers five times. Ensure that they can be switched on and off smoothly.
2. Check that all bolts are secured for cables. Tighten the bolts that are not properly secured.
3. Check that battery cables are correctly connected to battery terminals and that the battery voltage
meets the requirements.
• Switch on the circuit breaker on the battery pack.
• Check that the voltage between the positive terminal and the negative terminal is greater than 192 V.
• Switch off the circuit breaker.
4. Check that screws at the ground point of the battery pack are secured. Tighten the screws that are not
properly secured.
Inspecting the PDU
Commissioning mechanical performance
1. Switch on and off all circuit breakers five times. Ensure that they can be switched on and off smoothly.
2. Check that all bolts are secured for cables. Tighten the bolts that are not properly secured.
3. Check that screws at the ground point of the PDU are secured. Tighten the screws that are not properly
secured.
