Power Wiring Connection
Verify that the power source to which the filter is to be connected is in agreement with the nameplate
data on the filter. A fused disconnect switch or circuit breaker should be installed between the drive and
its source of power in accordance with the requirements of the NEC and all local electrical codes and
regulations. Refer to the drive user manual for selection of the correct fuse rating and class.
Refer to the drive user manual for instructions on interconnecting the drive and motor and the correct
start-up procedures for the drive.
The filter is designed for use with copper conductors with a minimum temperature rating of 75 degrees
C.
Wiring Checks
Using Figure 5-1: Basic Schematic Diagram
visually check the wired components to confirm,
verify, and correct wiring. Then, with a multi meter, check phase to phase isolation using the 100 K ohm
range. The multi meter will read the parallel equivalent of the bleeder resistors after the capacitors
initially charge. All phase to phase resistance values should be the same.
Check for the Following Faults:
•
Capacitor shorted
•
Capacitor bus not connected
•
Capacitor bus to chassis short
•
Paralleling wiring errors
WARNING
Input and output power wiring to the filter should be performed by authorized
personnel in accordance with the NEC and all local electrical codes and
regulations.
Cable lugs and mounting hardware are provided by the customer.
Any extremely low or high resistance readings indicate miswiring and may
result in damage to filter components if not corrected.
