Electrical connections
The lifting platform is delivered with a cable and plug connected to the lifting
platform’s motor housing. This is only a temporary solution in order to be able
to run the lift during assembly, until an authorised electrician connects the lift-
ing platform permanently.
Circuit:
The lifting platform has a single-phase motor which uses maximum
7.8A and possibly also a heating cable (accessory) of 220W. The lifting platform
therefore needs as a minimum a 10 A single-phase circuit with fuses (alterna-
tively a 13A circuit). The circuit must have a residual current device in accor-
dance with directives on electrical building installations etc.
The main switch shall always be placed in the vicinity of the lifting platform. The
main switch and the heating cable switch are often placed indoors to avoid unin-
tended interruption of the platform.
Electrical connection of lifting platform:
The power supply must be con-
nected to the terminal block located in a switch box in the motor housing. The
heating cable (if mounted) is also connected to the terminal block. The heating
cable can with advantage be equipped with a thermostat, so that it switches on
only when the temperature gets below the freezing point.
The connection diagram is found inside the motor housing.
Lighting:
A minimum of 50 lux lighting must be provided for the lifting plat-
form and control panel.
Main power switch:
The lifting platform must have a lockable main power
switch that breaks the voltage supply to the lifting platform, normally placed
together with the switch for heating cables indoors. This is to enable the lifting
platform to be without voltage during ser vicing, and when the lifting platform
should not be used. The normal solution is to pull a 4+earth wire cable from
the lift’s socket on the motor housing to the main switch and heating cable
switch which is normally placed indoors.
The main power switch shall be marked with:
THE MAIN POWER SWITCH MUST NOT BE SWITCHED OFF BEFORE
THE LIFTING PLATFORM IS AT THE LOWER LEVEL
