3-10 Commissioning Procedures
1560D-UM051D-EN-P – February 2005
Resistance Checks To ensure that resistors and connections have not been damaged during
shipment and installation, the following resistance tests should be performed
before energizing the starter.
1. Remove all power from the equipment.
Verify that all circuits are voltage free using a hot stick
or appropriate voltage measuring device. Severe injury
or death can result from electrical shock, burn, or
unintended actuation of controlled equipment.
2. Measure DC resistance per the following chart:
Location of Probes 1000 V 1300 V 1500 V 2300 V 3300 V 4160 V 5500 V 6900 V
Cathode to Cathode (KOhms) – – – – 22-30 23-31 21-29 24-32
Cathode to Cathode (KOhms) 17-23 19-25 20-27 21-29 40-53 43-57 60-80 Z 64-84
Cathode to Gate (Ohms)
10-40 10-40 10-40 10-40 10-40 10-40
10-40
10-40
Measured between terminals “Cathode” on SPGD Boards, upper two or bottom two within a phase.
Measured between terminals “Cathode” on SPGD Boards, top to bottom within a phase.
Measured between line and load terminals within a phase.
3. If abnormal readings are obtained, refer to Power Circuit Trouble-
shooting on page 10-9.
Start-Up 1. Remove any temporary jumpers or grounding devices used during
commissioning.
2. Check that all tools are removed from the equipment. Any tools or
hardware used or dropped during installation and commissioning must
be retrieved and accounted for.
3. Check that all barriers or covers removed during installation or com-
missioning have been securely mounted.
4. Close and secure all doors, and verify function of all interlocks that
prevent access to medium voltage compartments when the unit is
energized.
5. The controller is ready to power the motor.
