IMPORTANT: Provide each unit with a single-phase AC un-switched power supply from a circuit used for normal lighting.
Operating voltage shown on table on page 3.
NOTE: The battery must be connected to the charger board prior to applying AC power to the unit. Battery damage may occur if
the battery is connected longer than 24 hours without continuous AC power provided. See also "Important Battery Information",
page 4.
NOTE: The maximum mounting height of ELM2LF from ground is 11.1 feet, to meet the minimum illumination requirements of
NFPA 101 (current Life Safety Code).
NOTE: Do not connect battery or power unit until remote units (if applicable) are fully connected and wires are isolated from other
potentials (i.e. remote wires shall be isolated from earth ground).
JUNCTION BOX MOUNTING
-Some details shown below may vary-
On the mounting plate, remove the
1
round center knockout and the desired
pair of keyhole junction box knockouts.
Mounting Plate:
7"
CONDUIT SURFACE MOUNTING
NOTE: to avoid interference with components in the housing, use the most compact wire connectors appropriate to the wire gauge.
At upper center of the mounting plate,

remove the conduit connection
knockout. Also remove at least three
keyhole knockouts. Attach conduit and
secure mounting plate to wall surface
using fasteners with a minimum pullout
rating of 30 lbs. each.

INSTALLATION and WIRING
Route leads through the center

opening and use code-approved
connectors to make the connections.
(See Wiring Diagram, page 3). Dress
wires and connectors inside junction
box. Units with Remote Lamp Wires:
Connections to remotes wires should
also occur in the junction box. If no
remote lamps are connected, remote
lamp leads (+ and - low voltage DC)
should be left capped and dressed in
mounting plate as shown.
Junction boxes accommodated:
3-1/2" Round or Octagon
See Wiring Diagram, page 3. Make

code-approved wire connections to
the AC power supply, and remote
lamps (if applicable). Dress wires
into slots so that the connectors are
secured as shown in Figure 2 or
Figure 3.
Orient conduit fitting so that
all portions of it clear the
edge of the knockout
Secure wire connectors near the center or near
the upper latches. AVOID grouping wires and
wire nuts in the area of the PCB and the battery
as this may limit engagement of connector to
PCB.
Use washer (Grainger #4DAX6)
conduit fitting and rear housing if
conduit fitting interferes with battery.
Taking care not to pinch wires or
3
connectors dressed inside junction
box, secure mounting plate to
junction box screws.
NOTE: To ensure proper
engagement of the mounting plate
latches to the housing, DO NOT
OVER-TIGHTEN THE SCREWS.
