INSTALLATION INSTRUCTIONS
I. PERMANENT ELECTRICAL INSTALLATION
A job-specific schematic has been shipped separately in a packet of information which
includes this installation manual for reference by the electrical contractor or service
provider. Refer to this schematic and follow all applicable NEC requirements
throughout the electrical installation process.
Autoquip typically provides all the electrical control and signal devices. All required
wire, conduit, and main disconnect for field wiring is supplied by others. Unless
specifically included in the contract, the mounting and wiring of control and signal
devices is the user’s responsibility.
MAIN DISCONNECT: This should be a fused type disconnect which is to be located
within ten (10) feet of the lift. THIS ITEM IS NOT SUPPLIED BY AUTOQUIP AND IS
REQUIRED BY THE NEC (National Electrical Code.)
MAIN CONTROL PANEL: This panel is supplied and shipped loose by Autoquip, then
mounted & wired by others. All electrical components will be tied into this panel.
HYDRAULIC POWER UNIT: Autoquip supplies the power unit shipped loose and
recommends it be located adjacent to the unit. The power unit includes these electrical
components to be field wired to the Control Panel: a motor, a pressure switch, and an
electrical solenoid for the oil dump valve.
PUSH BUTTON STATIONS: Autoquip supplies one (1) P/B station for each level (under
normal conditions). Stations are to be mounted by an electrician. The Safety Code
(ANSI/ASME B20.1) dictates the position of these units to be, “remotely located so they
cannot be activated while standing on the lift carriage.”
LIFT STATUS LIMIT SWITCHES: Limit switches have been shipped loose to be field
mounted, wired, and adjusted to sense the status/position of the lift carriage (lower level
– for interlocks, upper level – for hydraulic re-pressurization circuit, and/or mid-level for
3-level applications). Refer to Figure 21.
OPTIONS AND ACCESSORIES: Items such as lift present lights, carriage lights, power
gates, horns, etc, will all require electrical installation and will increase the installation
time and the costs.
