Installation and operating manual
G961.1 - 03/2012 EN-13
The equipment must be earthed via the power supply cable. The
earthing function must be tested (isolation inspection). Additional
measures may be necessary.
A generator rated at 3 times the hoist's nominal power can be
used if necessary (generator's nominal power rating [kVA] =
number of hoists x hoist's nominal power rating [kW] x 3). The
operator must earth the generator. The earthing function must be
tested (isolation test).
The existing connection used must be equipped with a 30 mA
safety switch (FI or RCD) and overload protection (automatic
circuit breaker with K- feature) in accordance with the circuit
diagram and the order specifications. The starting current is three
times the nominal current of the hoist.
y Three-phase current: 400 V (3P + N + PE), 50 Hz
y
Alternating current: 230 V (P + N + PE), 50 Hz
The longer the power supply cable, the larger the cable cross-
section must be.
– Secure hanging cables with cable ties (1), see Fig. 25.
– Use heavy duty rubber lines with support elements.
Determining the required cable cross-section:
The following tables apply for hoists of 50 Hz. When 60 Hz hoists
are utilized, greater cable diameters must be used, depending on
the power.
– Determine the code letter (e.g. 'C') using Table 5. On hoists
with two speeds the maximum rope speed is the determin-
ing factor.
– In Table 6 determine the cable cross-section required for the
code letter.

Mount the rope
DANGER!
Danger of severe accidents caused by incorrect anchor-
ing or damaged ropes!
Might result in severe injuries or even death!
–
The rope must hang free.
– The rope must never run over an edge!
Risk of injury through stabs and cuts!
Broken wires in the wire rope can result in protruding wires!
Protruding wires can cut or stab through safety gloves!
–
Wear suitable leather protective gloves when working
with wire ropes.
– Never let the wire rope run through your hands.
Danger of crushing or being pulled in!
When threading the rope in there is a risk of fingers or the
entire hand being pulled in with the rope or being crushed on
the pulleys and rope guides!
–
Never touch the rope whilst the hoist is in operation! Do
not reach into the inlet or outlet of the hoist.
– Maintain a suitable distance from the rope.
– Watch out for rope loops.
Note:
If the anchoring point for the rope is located above the hoist the
rope must be fastened before it is fed into the hoist.
Driven reeler
The first rope turn on the rope reel provides the basis for rope
winding. The rope guide deposits the rope following the first rope
turn.
–
You must ensure that the first rope turn is wound on cleanly
and tightly.
– Choose the path and the rope length such that the last turn
of the rope always remains on the rope reel.
