Note:
1. This module is not polarity sensitive.
2. N / C = Not Connected.
Agency Compliance
1. Voltages up to 133V may be different phases on adjacent output points.
2. Voltages over 133V of different phases must have an output point separation
between them. For example: Output 1 and 2 - Phase A, Skip Output 3, Output
4 - Phase B.
CAUTION
Failure to follow these instructions can result in injury or equipment damage.
Connectivity Compatibility
Each output point must be fused with an external fuse. The recommended fuse is
a 5 A fuse (Part # 043502405) or any other fuse with an I2T rating of less than 87.
Failure to follow these instructions can result in injury or equipment damage.
CAUTION
Wiring Compatibility
If an external switch is wired to control an inductive load in parallel with the module
output, then an external varistor (Harris V390ZA05 or equivalent) must be wired in
parallel with the switch.
Failure to follow these instructions can result in injury or equipment damage.
