Wiring the Redundant Power Inputs
The top two pairs of contacts of the 10-contact terminal block connector
located on the top panel of the OnCell G3150A-LTE are used as the two
DC inputs. 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.
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 top panel of the
OnCell G3150A-LTE.
ATTENTION
Before connecting the OnCell G3150A-LTE to the DC power
inputs, make sure that the DC power source voltage is stable.
Wiring the Relay Contact
The OnCell G3150A-LTE has one relay output, which consists of the two
contacts of the terminal block on the OnCell G3150A-LTE’s top panel.
Refer to the Specifications section for detailed electrical requirement. The
relay contacts are used to indicate user-configured events. The two wires
attached to the relay contacts form an open circuit when a
user-configured event is triggered. If a user-configured event does not
occur, the relay circuit will be closed.
