Wiring the Relay Contact
The EDS-600 has a set of relay outputs. The relay contact uses two of the
terminal block’s contacts located on the EDS-600’s front panel. 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.
In this section, we illustrate the meaning of the two contacts used to connect
the relay contact.
FAULT
:
The relay contacts of the 6-pin terminal block connector are used to detect
user-configured events. The three 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.
The relay output has current carrying capacity of 1 A @ 24 VDC.

Wiring the Redundant Power Inputs
The EDS-600 has two sets of power inputs, power 1 and power 2, which are
located on the EDS-600’s front panel. Power 1 is the bottom two contacts on
the upper 6-contact terminal block and power 2 is the top two contacts on the
lower 5-contact terminal block.
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-600’s front panel.
