Warning When installing the unit, the ground connection must always be made first and disconnected last.
The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site.
Note
Typically, green or green/yellow is used for ground. Make certain the lead color coding you choose for the DC-input
power supply matches lead color coding used at the DC power source.
Note Install a 20A maximum, 60 VDC listed breaker at the power source.
Step 1 Ensure that the power switch is in the standby (off) position.
Step 2 Ensure that the –V and +V leads are disconnected from the power source.
Note Use only 12-AWG or 2.5-mm copper installation wire.
Using a wire stripper, strip approximately 0.55 inch (14 mm) from the –V and +V leads.
Step 3
Do not use soft-soldering to consolidate the strands.
