Wiring Instructions
1.
Turn power Off to the Control Unit
and
the feed to the
PB
,
ELVI
, or
FDBI
!
2.
Mount standard U.S. 2-gang wallbox* (available from Lutron,
P/N 241-641), 3 1/2 in. (87 mm) deep is strongly recom-
mended, 2 3/4 in. (68 mm) minimum. Allow at least 4 1/2 in.
(110 mm) clearance above/below Interfaces to ensure proper
heat dissipation.
3.
Strip 1/2 in. (12 mm) insulation from all wires in wallbox and
wire as shown. All connections are made using #12 AWG
(2.5 mm
2
) wire. Power terminals can accept up to two
#12 AWG (2.5 mm
2
) wires. The NEUTRAL N terminal is for
the Control neutral,
not
the load neutral! The recommended
installation torque is 9.0 in.
●
lbs. (1.0 N
●
m) for line voltage
connections.
Single-Feed Wiring for PB/ELVI
120V and 220-240V
The
PB/ELVI
may be on the same circuit as the Control
Unit
only if
the total load does not exceed the rating of
the breaker.
Dual-Feed Wiring for PB/ELVI
120V and 220-240V
The load breaker/MCB can be on a different phase than the control
breaker/MCB.
* Wallbox may be flush mounted or surface mounted. If mount-
ing Interface in a panel, please refer to Panel Mounting section
for important information.
