Connecting Power

Power can come from an external DC supply or a lead acid battery pack with a solar panel.

Connecting DC Power

EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-
hazardous. Performing this operation in a hazardous area could result in an explosion.
When power comes from an external DC supply, connect using the +DCIN and –DCIN
terminals. Use standard copper wire (#18 AWG minimum). The device supports both 12V
and 24V power supplies. It accepts DC voltage from 10.5 to 30V; the amount of power
required varies depending upon the options used.
Important
If your installation uses DC power for main power, do not wire battery power as a
secondary (back up) power source. Certification only allows a single main power source;
wiring both sources will void your certification.
