Gear unit with heating

Never switch on the heating elements, unless complete immersion of the heating
element in the oil bath is ensured. Fire hazard!
• Wire the temperature monitor electrically.
• Wire the heating system electrically.
• Wire the level monitoring device electrically.
6.6.4 Gear unit with oil­temperature monitoring system
• Wire the resistance thermometer with the evaluating instrument (to be provided by the customer)
electrically.
6.6.5

Gear unit with vibration monitoring at the bearing points

• The bearing­monitoring device must be fitted by the customer.
6.7 General notes on add­on components
For operating and servicing the components described in section 6, the pertinent instructions
manuals and the specifications in section 5 must be observed.
For technical data, refer to the data sheet and/or the list of equipment.
All cable lead­ins at electrical devices should be insulated as required by the operating
environment.
All add­on parts must satisfy the requirements in Directive 94/9/EC.
Simple electrical means (such as monitoring devices, switches, Pt 100 resistance
thermometers) without identification in accordance with Directive 94/9/EC are to be
connected intrinsically safely by suitable isolation amplifiers.

Final work

• After installation of the gear unit check all screw connections for tight fit.
• Check the alignment after tightening the fastening elements (the alignment must not have been
changed).
• Check that all the devices which have been demounted for transport reasons have been refitted.
For this refer to the details in the data sheet, the list of equipment and the associated drawings.
Any oil­drain cocks must be secured against accidental opening.
If an oil­sight glass is used for monitoring the oil level, it must be protected against
damage.
• The gear unit must be protected against falling objects.
• Protective devices for rotating parts must be checked for correct seating. Contact with rotating parts
is not permitted.
A potential equalisation in accordance with the applying regulations and directives
must be carried out!
On the gear units threaded holes are available for establishing an earth connection.
This work must always be done by specialist electricians.
• Cable entries should be protected against moisture.
