5.1 Operating Conditions
5.1.1 General Information
Maximum ambient temperature,
maximum setup elevation
The power conductors as stated in the selection data will be reached at the
following conditions:
Ambient temperature: 0...+86.00°F
Installation altitude: 0...1,000 m above sea level
The power data is reduced according to the diagram below at deviating con‐
ditions. Do occur deviating ambient temperatures and higher installation alti‐
tude at the same time, the power data has to be multiplied with both factors.
1 Utilization at a higher ambient temperature of more than 86.00°F.
2 Utilization at a higher installation altitude than 1,000 m.

Protection class According to DIN EN 60529-1:2000-09, the motor with mounted GTE plane‐
tary gearbox is protected by the housing against
●
contact of parts under load or moving parts
● Penetration of firm foreign bodies and water
At motors and the mounted servo gearboxes GTE the following protection
class IP 54 is valid
●
for the housing of motor and gearbox
● for the output shaft of the gearbox
● for the power and encoder connection on the motor at professional
mounting.
The first reference number defines the degree of protection against contact
and penetration of foreign bodies. The reference number 5 means
●
Protection against penetration of dust (dust-proof)
● Complete protection against contact
The second characteristic numeral defines the degree of protection against
water. The reference number 4 means
●
Protection against splashed water.
Surface protection
The gearboxes are surface-protected by the Citrox-method. The Citrox-meth‐
od is an environmentally-sound, thermo-chemically diffusion-method, where‐
by wear behavior, corrosion-resistance and fatigue resistance of the gearbox
housing are improved.
