V23C_09.13
Technical information
Socked circuit includes two 230 V /50 Hz
sockets (E1 and E2). The sockets are pro-
tected against electric shocks through
an automatic fuse (F4) and with a fault
current pro tection of 30 mA.
Electric cables
WARNING!
THE MAIN SWITCH (Q2) IN PLAT-
FORM ELECTRIC BOX DOES
NOT DISCONNECT THE ELEC-
TRICITY OUT OF THE SOCKETS
(E1 AND E2) AND THE HOOTER
(H2).
!
The electricity supply from the chassis
elec tric box to the platform electric box
will be supplied with a 5x6 mm
2
cable.
The electric system of the platform con-
sists of several electric equipment (mo-
tors, brakes, hooter, safety switches and
re mote control). This equipment has been
connected by using cables 2.5 mm
2
and
1,5 mm
2
(Cu-cored cross-section).
Protection against electric shocks
As an additional system of anti-electric
shock protection, neutralisation is ap-
plied. All accessible metal parts and
casing of electric equipment such as
sock ets, switches, hooter, electric motor
and brake are connected with the main
pro tective terminal PE, situated inside the
remote control device, with the help of
protective conductors.

Protection against lightning
Platform should be connected to light-
ning protection system of the building /
worksite. If there is no such system avail-
able, the earthing must be made accord-
ing to local requirements. The earthing
resistance should not exceed 10 Ohms.
An example:
5 % of 400 V is 20 V (min. supply voltage
for proper operation of the platform is 400
V - 20 V = 380 V).
The max voltage drop of 20 V will be
reached with a total cable (5 x 6 mm
2
)
length of appr. 100 metres. Total cable
length = supply cable length +cable con-
necting the chassis and platform.
