InstallIng the eMRs-W-D
The EMRS0-W-D is a center-off momentary contact clo-
sure switch that connects to the contact closure inputs of
the EM 1400 Series Relay Panel.
Placement and Wiring
“Home-run” the switch to the contact-closure inputs on
the EM1400: The green wire goes to the ground input
(gnd). Note that this is not “Earth Ground” but a float
-
ing common connection for the electronics. The wires
should at no time be allowed to touch “earth ground.”
The blue and white wires each go to one of the inputs
labeled with numbers 1-14. See the “Contact Closure In-
puts” section of the EM1400 Series Installation Manual
for more information.
If the wire from the switch to the panel exceeds 200 feet
the cable should be shielded and the shield attached to
the Gnd (common) wire at the panel only. It is not con-
nected at the switch end.
The inputs are not preprogrammed. They have to be
programmed for the rocker switch to actuate a relay or
relays in the system. See the EM1400 Quick Hook-Up
Guide and System and Software Start-Up Manual for
instructions on how to do this.
This center-off momentary switch has two separate
contacts and uses two inputs. To turn a load(s) on and
off, program one input as “momentary on” and the other
as “momentary off.”
