Emergency Lighting Transfer System User Manual 9 Planning wire entry into the ELTS cabinet The Emergency power connections must enter the cabinet from the top or side of the cabinet within six inches of the top left corner. Control, Normal power sensing and options wires connect most easily if they enter above the Remote station terminal or just below the Emergency sensing terminal on the left side of the cabinet. Note: Do not run the control, normal power sensing and options wiring in the same conduit as Emergency phase or load power wiring. Load wires in from the dimmer rack and out to the lighting loads connect most easily if they enter through the bottom of the cabinet either between or beside the transfer switch assemblies. Note: Except for the emergency power supply wires, which must enter near the top left corner of the cabinet, recommended conduit entry locations may be changed based on your installation requirements.

Mounting the cabinet After determining where you want to install the cabinet, follow these instructions. 1. Install two 3/8" bolts 24.25 inches apart for the lower two support slots (the installer must supply the mounting hardware). 2. Use the mounting dimensions from Figure 5: ELTS cabinet mounting dimensions on page 9 to drill the holes for the upper two 3/8” bolts. 3. Place the ELTS cabinet on the wall supported by the two lower bolts. Caution ELTS cabinets are very heavy. Make sure you have adequate equipment (or help) to lift the cabinet into place and support it while you secure the top two bolts. 4. Secure the ELTS to the wall with the two upper 3/8" bolts. Installing Remote stations (optional) 1. Install a standard two gang backbox (4" x 4" x 3.5") and run conduit from it to the ELTS cabinet. 2. Pull five conductor, Class 2 (12 Vdc) wiring through from the backbox to the cabinet. 3. Connect the wires to the terminal strip on the back of the remote station. Make a note of each wire’s terminal assignment. Connect the five conductor class 2 wires to terminals 1, 2, 3, 4 and 5 (wire colors may vary) 1 NORMAL OPERATION NORMAL POWER 2 3 4 5 6 EMERGENCY OPERATION AUTO EMERGENCY POWER Figure 7: Remote station terminal connections 4. Install the Remote station onto the backbox with four 6 - 32 x 1/2” oval head machine screws (provided). 5. To install multiple Remote stations, repeat steps 1 – 4, wiring in parallel between Remote station terminal blocks. Note: To avoid confusion, use the same wire terminal assignment at each Remote station you install. Refer to Connecting Remote stations to the ELTS on page 17 for instructions for connecting Remote station wiring inside the ELTS cabinet. Emergency Lighting Transfer System User Manual 11 Connecting power and control wiring to the ELTS cabinet Warning! To prevent death or injury due to electrical shock, Normal and Emergency power to the ELTS must be turned off any time you are connecting or servicing any ELTS. Connecting Emergency power (standard systems) Emergency power connection lugs Note: Standard ELTS systems connect Emergency power to phase lugs and distribute it through pre-wired overload protection circuitry. Discrete systems do not have Emergency power lugs. Go to Connecting Emergency power (Discrete systems) on page 13 for instructions. The Emergency power lugs are in the upper left of the ELTS cabinet. The ELTS is available in one or three phase power configurations. 1. Cut a hole within six inches of the top left corner of the ELTS cabinet Note: Top conduit connections are recommended to reduce the cable bending necessary to connect to the lugs. 2. Install conduit and pull the Emergency power cables into the cabinet. 3. Using Figure 9, below, connect phase power cable to the correct lug: Three phase power cables connect to lugs A, B, and C ▼ Single phase power cables connect to lugs A and B Note: You cannot connect an ELTS designed for three phase operation to single phase power or a single phase ELTS to a three phase source. 4.
