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 filter 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.
For 3A
– 110A panel mounted filter applications, interconnection between the filter, its power
source, and the drive is shown in Figure 4-2 (p11).
For 130A
– 600A open panel filter applications, interconnection between the filter, its power
source, the resistor panel, and the drive is shown in Figure 4-2 (p11).
For all filters supplied in general purpose NEMA 1/2 & 3R cabinets, interconnection between the
filter, its power source, and the drive is shown in Figure 4-3 (p12).
Wire gauge range and terminal torque requirements for the dV Sentry and the resistor panel are
shown in Table 4-2 (p13).
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.
