FAULT
:
The two sets of relay contacts of the
6-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. If a
user-configured event does not
occur, the fault circuit remains
closed.
Wiring the Redundant Power Inputs
The EDS-P510 has two sets of power inputs—power input 1 and power input
2. The top two contacts and the bottom two contacts of the 6-pin terminal
block connector on the EDS-P510’s top panel are used for the two digital
inputs. The top and front views of one of the terminal block connectors are
shown here.

STEP 1
: Insert the
negative/positive DC wires into the
V-/V+ terminals, respectively.
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 EDS-P510’s top
panel.
Wiring the Digital Inputs
The EDS-P510 has two sets of digital inputs, DI 1 and DI 2. Each DI consists
of two contacts of the 6-pin terminal block connector on the EDS-P510’s top
panel, which are used for the two DC inputs. The top and front views of one
of the terminal block connectors are shown here.
