Grounding the ME-10-T
Grounding and wire routing help limit the effects of noise caused by
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface before connecting the devices.
ATTENTION
This product should be mounted to a well-grounded mounting
surface, such as a metal panel.
Wiring the Alarm Contact
The alarm contact is made up of the three middle contacts of the terminal
block on the ME-10-T’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 explain the meaning of the three contacts used to
connect the alarm contact.
RELAY:
The three middle contacts of the
8-contact terminal block connector are used to
detect both power faults and port faults. The two
wires attached to the fault contacts form an open
circuit when:
1. The ME-10-T has lost power from one of the DC
power inputs.
OR
2. One of the ports for which the corresponding
PORT ALARM Dip Switch is set to ON is not
properly connected.
If neither of these two conditions occurs, the fault
circuit will close.
Wiring the Redundant Power Inputs
STEP 1:
Insert the negative/positive DC wires
into the V-/V+ terminals.
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.
