Relay:
The two contacts of the 4-pin terminal
block connector are used to detect
user-configured events. The two wires
attached to the fault contacts form an
open circuit when a user-configured
event is triggered or there is no power
supply to the switch. If a user-
configured event does not occur, the
fault circuit remains closed.
Wiring the Redundant Power Inputs
The EDS device includes both high-voltage and low-voltage products.
For the low-voltage (LV models) products, there are two power inputs
for redundancy; for the high-voltage (HV models) products, there is
only one power input. Refer to the instructions and diagram below on
how to connect the wires to the terminal block connector on the
receptor.
STEP 1:
Insert the Positive/Negative
DC or Line/Neutral AC wires into the
V+/V- or L/N terminals, respectively.
STEP 2:
To keep the DC or AC 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 EDS devices’ right side.
