Conditions for safe operation
General informa-
tion
Servomo-
tor/inverter com-
bination
• The listed servomotor/inverter combinations are recommended for category II3GD
servomotors. Servo inverters that have similar values with respect to output current
and output voltage (EN 60079-15) can also be used.
• The listed servomotor/inverter combinations are recommended for category II3D ser-
vomotors. If you want to operate category II3D servomotors on other servo inverters,
the maximum speeds/frequencies, the thermal motor protection as well as the ther-
mal torque limiting characteristic curves must also be observed. In addition, we
strongly recommend you use a frequency inverter matching the respective power rat-
ing.
Temperature
class and sur-
face temperature
• The maximum surface temperature of II3D servomotors is 150 °C.
• II3GD servomotors are in temperature class T3 and have a maximum surface tem-
perature of 150 °C.
Protection
against excessive
temperature
See chapter 'Protection against impermissibly high surface temperatures' on page 23.
NOTE ON EXPLOSION PROTECTION
The following applies:
• Use as category II3D unit in zone 22
• Use as category II3GD unit in both zone 2 and zone 22
NOTE ON EXPLOSION PROTECTION
Install the servo inverter outside the potentially explosive atmosphere.
