The power conductors as stated in the selection data will be reached at the
following conditions:
Ambient temperature: 0...+86.00°F
Setup elevation: 0...1,000 m above sea level
The power data is reduced according to the diagram below at deviating condi‐
tions. Do occur deviating ambient temperatures and higher setup elevations 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 setup elevation than 1,000 m.

Utilization at higher ambient temperature and higher setup elevation
According to DIN EN 60529-1:2000-09, the motor with mounted GTE planetary
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 mount‐
ing.
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 contact protection.
The second characteristic numeral defines the degree of protection against
water. The reference number 4 means
●
Protection against splashed water.
The gearboxes are surface-protected by the Citrox-method. The Citrox-method
is an environmentally-sound, thermo-chemically diffusion-method, whereby
wear behavior, corrosion-resistance and fatigue resistance of the gearbox
housing are improved.
