CAUTION
VOLTAGE SPIKE MAY BE SUFFICIENT TO DAMAGE OR DESTROY MODULE
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.
The following table shows mapping terminal blocks and optional busbars.
