Wiring the Power Input
Top and front views of the terminal block connector are shown below:
STEP 1:
Insert the negative/positive DC wires
into the V-/V+ terminals, and the ground wire
into the GND terminal.
STEP 2:
To keep the DC wires from pulling
loose, use a small flat-blade screwdriver to
tighten the wire-clamp screws on the front of
the terminal block connector.
STEP 3:
Insert the plastic terminal block
connector prongs into the terminal block
receptor, which is located on the bottom panel
of the OnCell 3120-LTE-1.
ATTENTION
Before connecting the OnCell 3120-LTE-1 to the DC power
inputs, make sure that the DC power source voltage is stable.
