Connecting Input Power - ADC PowerWorx Power Distribution User Manual

Caution: Connecting the equipment to the wrong circuit may cause damage to the equipment or
the fuse platform. Make sure the fuse is the correct type and has the correct current rating as
specified by the equipment manufacturer.
Note: The continuous output load of the equipment during normal operation should not
exceed 80% of the rated value of the fuse. This allows some room for manufacturing
tolerances and voltage fluctuations in the plant power mains.

Connecting Input Power

Input power is supplied to the fuse platform through the single or dual terminal blocks located
on the rear of the platform. Each input terminal block consists of two pairs of 0.25-inch studs
that are used for connecting the BATT (battery –) and RTN (return +) input power cables.
The stud pairs are mounted on 0.625 inch centers and accept 2-hole compression lugs. The
maximum lug width is 0.62 inches. Nuts with captive washers are provided to secure the
compression lugs to the terminal block.
