5. Close cable clip and fasten with nut.
6. Included mounting tabs (F) and cable ties (C) may also be used for securing cables.

CAUTION: SHOCK, INJURY OR DAMAGE TO EQUIPMENT IS POSSIBLE! Avoid placing cables near moving parts and pinch points to avoid damage to the cables. Ensure there is enough slack in the cables to allow for up and down movement of the lift.

Connecting Control Wiring
WARNING: All wiring should be performed following the National Electric Code, ANSI/NFPA, and Canadian Electrical Codes, Part 1.

1. Unplug the SL236’s power cord (used for testing).

2. Remove the jumper wire (E) and supplied push button (B) wiring (previously installed in the Pre-Test Lift before Installation section) from the external terminal block. (See Figure 3)

3. Connect control wiring following instructions included with the third party automation and control equipment and user-supplied switching devices, and information in Table 1: Wiring Table.
   NOTE: Any knockouts removed in the SL236 must be replaced with a supplied rubber grommet (H).

4. Feed the video and/or communications cables through the knockout in the rear or top of the lift and connect it to the projector.
   NOTE: Ensure there is enough slack in the cables to allow for up and down movement of the lift.

5. Secure cables as necessary using supplied mounting pads (F) and cable ties (C).
   CAUTION: KEEP SL236 OPEN WHILE PROJECTOR IS RUNNING OR IN COOLING MODE! Premature bulb failure or damage to electrical components may occur if lift closes.
   NOTE: If SL236 is cycled up and down repeatedly the motor’s thermal overload protection will stop operation. Operation will resume when the thermal overload resets (usually within 3 to 5 minutes).

Connecting to Power Supply
IMPORTANT ! : This product must be connected to a grounded metal, permanent wiring system, or an equipment-grounding conductor must be run with the circuit conductors and connected to the equipment-grounding terminal or lead on the product.

WARNING : FAILURE TO DISCONNECT AND TERMINATE POWER LEADS PROPERLY MAY RESULT IN PERSONAL INJURY OR EQUIPMENT DAMAGE!! Licensed electrician must disconnect and terminate the leads to the power cord receptacle, and must hard wire the SL236 to a 12-amp power source.

1. Disconnect and remove power inlet from interior junction box.
2. Hardwire unit to a 120V 60Hz 12-amp power source.

NOTE: This unit was designed to have conduit run directly into the back of the interior junction box.
NOTE: If installing the SL236 in a drywall ceiling, remove the outside terminal block and cover with plate (D), using four 6-32 x 3/16″ Phillips pan head screws (G).
