to risk any material damage.
§Sorting bridges (SGR only)
The sorting bridge is used for safe storage on the opposite belt casing. The sorting bridge can be folded
by lifting it lightly up and raising it to an angle of 90°. The unfolded sorting bridge is flush with the belt
casing. The hinged design without a chute but with a sound absorbing panel attached at the bottom can
be fitted on the belt upon agreement. The maximum load of the sorting bridge is 25 kg.

Service
4.1 Transport
The delivered conveyor system with a length of up to 6 m is completely assembled, wired and set so that it is
ready for operation.
Conveyor systems with a length of more than 6 m will be delivered segments that have to be assembled.
When loading, use only hoists and load lifting devices approved for appliances 1.5 times heavier than the
conveyor system to be lifted. Only transport vehicles that are approved for the weight of the appliance may
be used.
The scope of delivery is specified in the shipping documents in accordance with the valid purchase
agreement and included with the delivery item.
4.2 Assembly
DANGER Hazardous electrical voltage
Electrical current can pose a considerable threat to life and physical well-
being and may lead to injuries.
Only an electrician or instructed staff under the guidance andsupervision of
an electrician may work on electrical systems or operational equipment; they
must comply with the electrical industry rules while doing so.
DANGER Defective emergency stop
In case of fault, e.g. from defective fuses,the drives may continue torun even
after the emergency stop has been pressed.
CAUTION Rotating machine parts
There is an indirect risk of injuries of the fingers caused by being pulled into
the appliance and crushing.
Avoid any direct contact with the running conveyor belt and the outlet, feeding
and deflection points during assembly or when performing any other work.
Never reach into the hazardous area of the conveyor system. Before
switching on the conveyor system, make sure there is no risk of reactivation of
the belt.
CAUTION Injury to persons
The segments and the conveyor belt may only be assembled by two persons.
Wear protective goggles and safety gloves at all times when placing and
joining the belt.
INFO Conveyor systems longer than 6 m
The following section only applies to conveyor systems longer than 6 m which
need not be delivered and mounted as a unit.
