Step 2: Control power wiring
The E-flex panel operates at 120-277VAC. Use following instructions to wire line voltage to the unit.
Warning:
RISK OF DEATH OR ELECTRIC SHOCK! Before installing input power to the
controller, make sure upstream source of power is off via a circuit breaker.
1. Use 14 to 12 AWG conductors (depending on breaker rating) to feed the control power wiring. The E-
flex controller draws less than .60A at 120V and
less than .34A at 277V.
2. The unit power supply has a black (Hot) and white
(Neutral) wire. Wire nut the Hot and Neutral of the
power feed to these wires as shown.
3. A stud is provided to land the ground wire.
4. Note: Alternately the unit control power can be
wired from the zone 1 feed rather than a separate
feed. This is especially true if UL924 is applied as
the unit must be powered by the
normal/emergency feed with zone 1 as the first
emergency zone.
Step 3: Line Voltage load wiring
The E-flex panel operates at 120-277VAC. Use following instructions to wire line voltage loads to the unit.
Warning
:
RISK OF DEATH OR ELECTRIC SHOCK! Before installing power to the power feeds,
make sure upstream source of power is off via a circuit breaker.
E-Flex is a feed-through device; this means that each switched output requires Line and Load wires.
Feed-Through Example –4-circuits, Individual Feeds
Load Wires: Two (2) 14 AWG to 12 AWG. Strip length –3/8 in., torque –7 in-lbs.
Neutral and Ground Wires: Wire nut each from feed to load.
Feed-Through Example –4-circuits, Normal/Emergency, 120V and 277V
Feeds
Voltage Barriers: Separate Normal/Emergency, 120V, and 277V. The voltage barrier is an accessory,
sold separately. Order Lehigh part number A1678.
