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 7 Lift requires 110V/60Hz at 2.3 Amps and is
supplied with a six foot power cord. The SVS 7 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).
