Installation Procedure - LEGRAND Wattstopper ELCU-200-347 Instrucciones De Instalación

Wiring Notes
1. You can connect as many NC contacts (including EMTS-100) in series on the jumper loop wire as you want to a single ELCU. You
cannot connect the NC devices in any other manner.
2. At no time can more than 5 ELCU devices can be controlled together by commoning their Test Loop wires to a Normally Closed
Test Switch (EMTS-100) and/or other NC contact closure.
3. If connecting ELCUs together via their test loop wires, you must maintain the polarity of their wires.
• ELCU units should be installed in accordance with state, local and national electrical codes and requirements.
• ELCU units are designed to attach to a junction box or electrical enclosures that are fitted with a 7/8" diameter opening (standard
1/2"knockout).
• ELCU units operate with power provided by two sources. Place a warning label on each enclosure that contains an ELCU unit.

Installation Procedure

1. Remove the locking nut from the ELCU unit and insert the unit's threaded nipple through the appropriate knockout. Tighten the
locking nut so that the unit is secured to the j-box or enclosure.
2. Connect the ELCU to the emergency lighting for the area controlled. Connect the Emergency wiring leads on the ELCU in series
with the emergency lighting load as shown in the wiring diagram. Connect the neutral for the emergency circuit to the Emergency
Neutral lead as shown in the wiring diagram.
