Installation Guide
ELCD 1008
Isolite Corp 31 Waterloo Ave, Berwyn PA
6
Note:
If using a separate neutral for the sense circuit, do not install the jumper. If using a three-wire
feed as shown above, install the jumper as described in step 3.
The ELCD 1008 has the ability to separate the sensing of normal power from the load itself; this allows you to
have a light switch or dimmer controlling the load when normal power is available, but to have the load transfer to
emergency power in the event of normal power loss.
The ELCD 1008 can be used with switched or dimmed power control.
Dimmed or Switched Load
1. See Wire and Terminal Specifications on page 4 for wire size, strip length, and terminal torque.
2. Terminate load wires.
a. Run a neutral and a hot load wire through conduit for the load to be transferred from the ELCD
1008 to the load position.
b. Terminate to the respective terminals LOAD 2N (neutral) and LOAD 1H (hot) in the ELCD 1008
enclosure, securing each terminal screw onto the wire.
3. Install a jumper wire between SENSE 4N (neutral) and Normal 6N (neutral).
4. Terminate normal power wires.
a. Run a neutral and a hot wire through conduit from the normal power source (controlled
dimmer or switch) to the ELCD 1008.
b. Terminate the neutral wire to the NORMAL 6N (neutral) terminal and secure the terminal
screw onto the wire and the jumper fork terminal.
c. Terminate the hot wire to the NORMAL 5H (hot) terminal and secure the terminal screw
onto the wire.
5. Terminate normal sense wire
.
a. Run a hot sense wire from a non–controlled output of the normal power source through
conduit to the ELCD 1008.
b. Terminate to SENSE 3H (hot) in the ECLD 1008 enclosure, securing the terminal screw onto the
wire.
6. Terminate emergency power wires.
a. Run a neutral and a hot wire through conduit from the emergency power
source to the ELCD 1008.
b. Terminate to the respective terminals EMERGENCY 8N (neutral) and
EMERGENCY 7H (hot) in the ELCD 1008 enclosure, securing each terminal screw onto the wire.
