Powering the Modular Switch

•

Commercially available 2 to 4 AWG wire is recommended for installations in the U.S.

•

Wire size should meet local and national installation requirements.

•

Grounding wires and grounding lugs are not supplied.

•

Strip the wires to the appropriate length for the lugs.

The wires connecting the DC power supply to the power source must meet the following

requirements:

•

DC Input Wire Size: 2 – 4 AWG (33.6 mm

2 to 21.2 mm2).

•

Primary Ground Wire Size: 2 – 4 AWG (33.6 mm

2 to 21.2 mm2) per power supply.

•

The conductors are copper.

Note: You can also use a 45° angled connector instead of the straight connector shown.

2. Use agency-approved compression (pressure) lugs for wiring terminations with a single 5/16"

mounting hole. Two-hole lugs should have 1/4" mounting holes on 5/8" centers.

The PWR-2700W-DC-R ground lug is a right-angle lug. Check the terminations for the appropriate

wire size. Use a ground wire of at least 2 – 4 AWG. Use only copper wire.

3. Slip on heat-shrink tubing on the wire ends before assembling the lugs on to the wire.

•

The lugs must be crimped with the proper tool.

•

The tubing should extend over the lug’s barrel and the wire's insulator.

4. Shrink the tubing with a heat gun.
