Wiring the Redundant Power Inputs
Two pairs of contacts of the 10-contact terminal block connector on the
WAC-1001’s top panel are used for the WAC-1001’ two DC inputs. Top
and front views of the terminal block connector are shown here.
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 WAC-1001’s top panel.
ATTENTION
Before connecting the WAC-1001 to the DC power inputs, make
sure the DC power source voltage is stable.
Wiring the Relay Contact
The WAC-1001 has one relay output, which consists of two contacts of the
terminal block on the WAC-1001’s top panel. Refer to the previous section
for detailed instructions on how to connect the wires to the terminal block
connector and how to attach the terminal block connector to the terminal
block receptor. These 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 remain closed.
Wiring the Digital Inputs
The WAC-1001 has two sets of digital inputs—DI1 and DI2. Each DI
consists of two contacts from the 10-pin terminal block connector. Refer
to the “Wiring the Redundant Power Inputs” section for detailed
instructions on how to connect the wires to the terminal block connector,
and how to attach the terminal block connector to the terminal block
receptor.
