Connecting The Electrical System - spanesi MINIBENCH MAXIPLUS Manuel D'utilisation Et De Maintenance

3.2.2. CONNECTING THE ELECTRICAL SYSTEM

For correct connection of the lift electrical system, proceed
as follows:
• Check the electrical distribution board powering the
lift control unit. It must be provided with a set of three
fuses and a correctly-set magnetothermal switch.
• Check the lift operating voltage and frequency: they
must correspond to the voltage and frequency of the
bodyshop supply mains.
The MINIBENCH MAXIPLUS operating voltage is specifi ed
in the plate on the control unit electric motor casing.
The machine electrical equipment is designed to operate
normally at 400 V 50 Hz.
• Insert the power cable plug into the socket on the
electrical distribution board.
• Together with the lift, SPANESI S.p.A. supplies a 2.5
m long cable with a 4-pin plug. This length is generally
suffi cient for the connections.
If it is impossible to position the control console close
enough to use the cable provided, the whole cable must
be re-done as follows (see fi gure 6) :
WARNING! Do not under any circumstances
splice electrical cables to the power cable.
• The power cable section must be adequate for the
load absorbed by the lift and for the distance between
the control console and bodyshop distribution board.
• The power cable must be connected to the lift
distribution board, passing it through the hole provided
(1) until it reaches the terminal block marked with the
power supply voltage (2 - fi g. 6).The three phase wires
must be fi xed to the respective terminals marked by
the symbols L1, L2 and L3.
The earth wire must be connected to the yellow-green
earth terminal.
• Before connecting the control unit power cable to the
distribution board, check that the distribution board
switch is set to "0", otherwise open the contacts.
DANGER! Always check the effi ciency of the
machine earthing system after connecting the
power supply. Faulty or inadequate connection
of the earth wire can cause serious injury and
even death.
• Complete the connection of the control unit to the
distribution board and close the cover by means of the
screws (3 - fi g. 6).
Check the correct electrical connection to the supply
mains as follows (see fi gure 7):
• Pull the mushroom-shaped emergency button until it
is released (1 - fi g. 7).
• Press the reset button (2 - fi g. 7) on the right of the
mushroom-shaped emergency button (1 - fi g. 7): the
white pilot light (3 - fi g. 7) will come on to indicate power
on. If there is no power, check the connections.
• Press the <ascent> button (5 - fi g. 7) for approximately
three seconds: the lift should move upwards.
If the lift does not move upwards, the motor polarity must
be changed as described in Paragraph "3.3 CHECKING
THE PHASES".
