3.8. Power requirement
3.8.1. Connections
The connection for the compressed air supply has
the size G 1 1/2.
Please use the corresponding hose lines for the
selected pressure.

WARNING
Danger of explosion
Operating at higher system pressures may result
in hazards due to overload.
When operating at lower system pressures, the
brake can grind and is therefore subject to very
high wear. Inadmissibly high heating may result.
The load capacity of the device is reduced. The
response of the control system decreases notice-
ably.

must be operated with a
nominal pressure of 6bar (85psi) (see specification
on the nameplate).

Figure 9)
The system pressure existing in the line must cor-
respond to the nominal pressure. Higher pres-
sures must be reduced.
After switching on, the adjoining nominal pressure
p1 reduces to the actual pressure p2. The extent
of the actual pressure p2 at which the product is
operated is dependent on
•
the weight of the load

and the
•
direction of movement of the load
(3)
.
When lifting the nominal load (load capacity) at the
specified lifting speed, the actual pressure p2 may
at a maximum be 10% below the specified nomi-
nal pressure of the hoist (measured immediately
before the lifting motor)!
