4 LOW VOLTAGE ELECTRICAL CONNECTIONS
4.1 DC LOW VOLTAGE CABLE INSERTION
The compression connectors have IP65 protection capability. All cables must pass through the
compression connectors.
4.1.1 Compression Connectors
Follow these instructions to correctly insert the cables:
1) Determine the number and size of the cables coming into and leaving the PWR-120.
2) Locate the correct compression connector sizes and positions relative to these cables.
3) Pass the cable end through the proper compression connector so that the gland material
seals around it when tightened.
There are three compression connector sizes with the following specifications:

4.1.2 Installing the AS-I Cable
Prepare the AS-I cable by stripping the wires and inserting first the compression connector
nut, then the AS-I cable sealing grommet.
Pass the AS-I cable through the compression connector and make sure there is enough length
to easily reach the 24 Vdc Terminal Block.
Seat the AS-I cable sealing grommet into the compression connector and tighten the
compression connector nut,
