6. Commissioning, operation
CAUTION!
Danger of tripping caused by improper routing of machine connec-
tions
Improperly installed machine connections such as cables, hoses or
pipelines can create tripping hazards, and can cause serious injury.
■
Route the machine connections so that no tripping sources are
present.
■
Do not use machine connections to assist carrying.
■
Mark unavoidable tripping sources with yellow and black marker tape.
Location
To prevent the risk of falling, work in an environment in accordance with EN12464 with
sufficient lighting, ≥ 300 lx.
To ensure adequate ventilation of the instrument, the outlet of the fan must not be
obstructed. Ensure a min. clearance of 30 cm.
Mounting and disassembly of components
All hoses or fittings and threaded connections connected to the GTU-10 must be
designed for operation of at least 50 bar.
Please be aware that the hose lines may be under high pressure and should be vented
into a tank after use.
The connections are sealed with plastic protective caps or adhesive foil. These protec-
tive caps and the adhesive foils must be removed before commissioning.
Protective system
The housing must, at all times, be closed and intact. Any operation with open or defec-
tive housing will void the operating licence.
Electrical connection
The power supply for the GTU-10 is made via male rubber connector in accordance to
IEC 60320 / C14. The permissible voltage range is indicated on the rating plate. Should
the customer's own power cable be used, it must have a minimum cross-section of
1.5 mm

.
The unit is only suitable for use in industrial environments.
There should be no connection to the public low-voltage supply without permission from
the power supply company concerned.
Behaviour on power loss
If the power should fail during operation, the electrical control system will prevent the
automatic restart of the compressor.
