Wiring the Relay Contact
The EDS-510A has two sets of relay outputs—relay 1 and relay 2. Each
relay contact uses two contacts of the terminal block on the EDS-510A’s
top 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 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-510A 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-510A’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-510A’s top
panel.
