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.
The typical interconnection diagrams that follow are shown for a motor load, but the load can be
either a motor or a transformer.
•
For modular filter applications, interconnection between the filter, its power source, the
capacitor(s), the common mode assembly and the drive is shown in Figure 5-1: Modular
Interconnection (p22) .
•
For filters supplied in general purpose NEMA 1/2 & NEMA 3R cabinets, interconnection
between the filter, its power source, the motor, and the drive is shown in Figure 5-2:
Enclosed Interconnection (p23) .
• For transformers, interconnection between the power source, the filter, the motor and the
drive is shown in Figure 5-4: Transformer Diagram (p25) .
Wire gauge range and terminal torque requirements as well as selecting conductors that
interconnect the reactor, capacitor(s) and common mode assembly are shown in Table 5-2: Torque
Ratings 380-480V (p27) and Table 5-3: Torque Ratings 600V (p28) .
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.
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.
On NEMA 3R enclosures, CAB-26AP and larger, no live parts shall be mounted
below 8 inches from the bottom of the enclosure.
