2.4.1 Temperatures

The permissible temperature range is determined by the following:

ƒ The lubricant specifications in connection with the expected oil temperatures in

operation (see chapter 8.1 and nameplate).

ƒ The thermal class of the motor considering the motor temperature expected during

operation (see nameplate and/or Operating Instructions of the motor).

The operating temperature is determined by the power loss, the ambient temperature and

the cooling system!

( Stop!

With mineral oil, the upper temperature limit for continuous operation is 80°C,

with synthetic oil and shaft sealing rings made of FP (Viton) 100°C. If these

temperatures are exceeded, measures are necessary to reduce the

temperature, see chapter 9.

} Danger!

Depending on the operating conditions, surfaces may be hot, provide

protection against accidental contact.

2.4.2 Ambient conditions

ƒ Gearboxes are protected against dust and spray water.

ƒ Motors according to their enclosure (see nameplate and/or Operating Instructions

for the motor).

ƒ Ambient media − especially chemically aggressive − can destroy shaft seals and

coatings (plastic). Abrasive media endanger shaft seals.

ƒ The installation site of the drive must be free of shocks and vibration.

ƒ Dirt of dust deposits impede the heat dissipation (cooling).
