Power Wiring Connection
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.
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.
The filter is suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical amperes at 480 volts when protected by Bussman type JJS, KTK,
For panel mounted filter applications rated 44 amperes and below, interconnection between the filter, its power source, and the drive is shown in
Figure 25. Refer to the drive user manual for instructions on interconnecting the drive and motor and the correct
The filter is designed for use with copper conductors with a minimum temperature rating of 75 degrees C.
Table 8 lists the wire range and terminal torque requirements for the power input and output connections by horsepower rating.
For panel mounted filters rated 52 amperes or more, the filter reactors are supplied on a sub- panel and the filter capacitors are supplied on
one or more assembles. Refer to Figure 26 for the interconnection diagram. The capacitor assembly should be located in the lowest temperature regions of the enclosure – generally toward the bottom – and the reactor assembly may be located in any region where the ambient temperature does not exceed 50 degrees C. Size the conductors interconnecting the reactor and capacitor assemblies to carry the current shown in Table 3. For terminal specifications on the capacitor assembly, refer to Table 9.
For filters supplied in general purpose NEMA 1, 2 & 3R cabinets, interconnection between the filter, its power source, and the drive is shown in Figure 27. Refer to Figures 29 to 32 for the location of input, output, ground and over temperature switch terminals. Refer to the drive user manual for instructions on interconnecting the drive and motor and the correct
For filters supplied in industrial style NEMA 1 cabinets, interconnection between the filter, its power source and the drive is shown in Figure
28.Refer to Figures 33 to 37 for the location of input, output, ground and over temperature switch terminals. Refer to the drive user manual for instructions on interconnecting the drive and motor and the correct
Grounding and Ground Fault Protection
The filter must always be grounded with a grounding conductor connected to all ground terminals.
Due to high leakage currents associated with variable frequency drives, ground fault protective devices do not necessarily operate correctly when placed ahead of a matrix filter feeding a drive. When using this type of device, its function should be tested in the actual installation.
