4.6 Electrical Connections
The manufacturer of the suspended access equip-
ment is responsible for the connection of the TIRAK
®
hoists taking into consideration the wiring diagrams
provided.
DANGER!
The electrical connection for TIRAK
®
winches
must conform to EN 60204-1.
The lead must be protected by fuse by the
customer.
Always pull the plug out before opening a
central control!
a)
Ensure that the mains voltage is adequate for
the motor of the TIRAK
®
:
– Three phase:
400 V (3P + E + 0), 50 Hz,
16 amp rated plug and socket
– Single phase:
230 V (2P + E), 50 Hz,
16 amp rated plug and socket
If in doubt ask.
b)
To avoid power loss between power source
and the TIRAK
®
always use power cables with
adequate cross sectional area.
See tables 6a and 6b.
Table 7a
indicates the reference letter of the TIRAK
®
model and the mains supply voltage.
Maximum speed must be used for TIRAK
®
with
two speeds.
Table 7b
gives the minimum cable
cross section based on the
reference letter.
c)
Use only heavy duty cables
with incorporated strain relief.
d)
Hanging cables longer than
30 m should be fixed by means
of a cable sleeve or cable clamp.
(Fig. 33).
e)
When using a generator its out-
put must be at least 2.5 times
greater than the TIRAK
®
power
consumption.
