5.11 PUTTING THE GEARBOX INTO SERVICE
The gearbox has been tested in the factory by the manufacturer.
Before starting it up, make sure:
●
That the machine or part of the machine in which the the gearbox/gearmotor is to be installed has
been declared to conform to the requirements of the Machinery Directive 2006/42/EC and to any other
relevant and applicable safety standards.
●
That the gearbox mounting position in the installation corresponds to that prescribed and indicated on
the nameplate. This requirement does not apply to gearbox sizes from 27 to 49, unless they are ATEX-
compliant (where applicable).
●
It is expressly forbidden to install the gearbox at an angle without having consulted and obtained
authorisation from the manufacturer’s technical service. A tolerance of ± 5° with respect to the theoretical
plane of installation is permitted only for shaft mounted installations. This requirement does not apply to
gearbox sizes from 27 to 49, unless they are ATEX-compliant (where applicable).
●
That the electrical power supply is suitable and operational as prescribed in EN 60204-1 and is correct
grounded.
●
That the rating of the power supply to the motor and any installed electrical devices corresponds to that
prescribed and is within ±10% of the rated value.
●
That the oil level in the gearbox/gearmotor and any lubricated accessories is as required and that there
are no leaks from any plugs, seals or pipes.
●
That any parts and/or accessories disconnected for transport purposes have been reconnected.
●
That any of original guards removed for transport purposes have been refitted.
On startup of the gearbox/gearmotor:
●
Check that there are no unusual noises and/or vibrations.
●
After the first 100 hours of operation, check the tightening torque of all bolt couplings:
- machine side flanges
- motor flanges
- supports
