Connecting Input Power
IMPORTANT: It is good practice to turn off input and load power, and unplug the power
terminal block before making wire connections. Otherwise, your screwdriver blade can
inadvertently short your terminal connections to the grounded enclosure.
➊
Identify PWR1, GND, PWR2, GND contacts on terminal block. Then identify
power wire and ground wire.
➋
Insert the wire of your DC supply or Battery supply into the PWN1 and/or
PWN2 contacts of the terminal block connector, and fastening the terminal
screws to prevent the wires from coming loose.
NOTE: For best reliability, please install both of PWN1 and PWN2 for power redundant.
