4.2 Lubricant cooling using an external cooling system (cooling unit)
Danger!
When commissioning the cooling system, the operating instructions of the oil /air
cooler or oil / water cooler must be observed.
Danger!
The drive unit may only be commissioned after the cooling system has been connected
and commissioned.
For operation in explosion hazard atmospheres, only approved and labelled cooling
systems may be used. The ATEX labelling must conform to the details of the system
and/or machine design.
Attention!
The filter of the cooling system must be checked regularly (see Section 5.1).
Attention!
With oil / air coolers an adequate air intake must be ensured. The air inlet grille and the
fan blades must be kept clean.
Note!
If there is a danger of frost the operator should add a suitable anti-freeze solution to the
cooling water.
Temperature regulation can optionally be provided by using a temperature switch or a resistance
thermometer, which is installed in the oil sump of the gear unit.
Danger!
The temperature of the cooling water and the cooling water flow rate must be
supervised and ensured by the operator.
The ATEX approval is void if these instructions are not observed!
