Wiring the Relay Contact
Each PT switch has one relay output. Refer to the next 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.
FAULT:
The relay contact of the 10-pin terminal block connector are used
to detect 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.
Wiring the Redundant Power Inputs
Each PT switch has two sets of power inputs: power input 1 and power
input 2.
STEP 1:
Insert the dual set positive/negative DC wires into PWR1 and
PWR2 terminals (+
→
pins 1, 9; -
→
pins 2, 10). Or insert the L/N AC
wires into PWR1 and PWR2 terminals (L
→
pin 1, 9; N
→
pin 2,10)
STEP 2:
To keep the DC or AC wires from pulling loose, use a screwdriver
to tighten the wire-clamp screws on the front of the terminal block
connector.
Note 1:
The PT switch with dual power supplies uses PWR2 as the first
priority power input by default.
Note 2:
For dielectric strength (HIPOT) test, users must remove the
metal jumper located on terminals 3, 4, and 7, 8 of the terminal block to
avoid damage.
