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
EDS-516A 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 EDS’ top panel are used for EDS’ 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 EDS-516A’s top panel.
Wiring the Digital Inputs
EDS-516A 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 EDS’s top panel, which
are used for EDS’s two DC inputs. The top and front views of one of the
terminal block connectors are shown here.
