Connecting Low DC Power
To connect a low DC power supply to the device, do the following:
CAUTION!
Electrical hazard – risk of damage to equipment. Do not connect AC power cables to a 12, 24 or 48
VDC power supply terminal block. Damage to the power supply may occur.
IMPORTANT!
When connecting the device to a DC power source, make sure the source provides only positive
voltage.
NOTE
The screw-type terminal block is installed using Phillips screws and compression plates, allowing either
bare wire connections or crimped terminal lugs. Use #6 size ring lugs for secure, reliable connections.
1. Connect the positive wire from the power source to the positive (+) terminal on the terminal block.
