SVS 7HSE 110V - Manual (Page 9)

b. Installing the Lift in the Ceiling
1. Raise the Lift into the ceiling and line up the six (6)
mounting holes in the Lift's top frame with the 1/2”
threaded rods of the supporting structure. Make sure
that there is a top nut and a flat washer on each threaded
rod before the Lift is mounted. See Figure 7. (Plenum
Shrouds & Decorative Cover require additional
hardware installed on the threaded rods before the Lift.)
2. Once the Lift's top frame has been inserted, add a
hexnut to each threaded rod below the Lift frame.
Always leave the top nut loose to allow adjustments
until the Lift is leveled.
3. Level the Lift's top frame side-to-side and front-to-back
using the lower hexnuts on the threaded rods.
4. Once the Lift is leveled, secure the Lift to the threaded rods by tightening the upper hexnuts. Do not
over tighten the fasteners as it could distort the Lifts top frame.
5. If the Power Sensor is used, please refer to the Power Sensor Instructions, otherwise, plug the 12-pin
connector of the Wall Plate Controller into the 12-pin socket on the Lift's gray electrical box mounted on
the Lifts top frame. The Wall Plate Controller includes 75-feet of cable and is shipped with the Lift. It is
located in the cardboard box attached to the lid of the Lift's shipping crate.
6. Once the Lift is properly installed in the ceiling and leveled, you can remove the shipping blocks.
Remove the blocks by removing the screws and tie-raps holding them in place.
TO AVOID CABLE SPILLS
• Do not push the lift bottom frame upwards once the Lift has been installed.
• Make sure that there are no obstructions in the Lifts path. If the bottom frame is lowered onto an
obstruction the cable will slack and spill over the cable drum. If the cable spills over the cable
drum and the Lift is not stopped the cable will back-wind onto the cable drum causing severe
damage to the Lift and accessories.
8. ELECTRICAL CONNECTIONS
Electrical connections should be made at this time. The SVS 7HSE Lift requires 110V/60Hz at 2.3 Amps and is
supplied with a six foot power cord. The SVS 7HSE Lift is controlled with a 24VAC Low Voltage Controller
called the Wall Plate Controller. This controller can easily be connected to external controllers like Crestron,
AMX, Extron, etc. The Wall Plate Controller is supplied with 75-feet of cable (22 AWG, 9 conductor).
