Electrical installation - Hazards
WARNING
Warning of hot surfaces!
The motor heats up during operation.
The surface temperature can exceed 130 °C.
Take protective measures to prevent inadvertent contact with the
motor, e.g. install guards.
Make sure that no temperature-sensitive parts, e.g. connection
cables, are attached or fastened to the motor.
Provide sufficient heat dissipation. For the following locations of
the motor, the respective maximum temperatures apply:
Connector:
≤ 130 °C
Cable: ≤ 90 °C
Flange: ≤ 65 °C
Higher temperatures require a derating. Derating tables for
operating the motors at higher temperatures can be found in the
User Manual for servomotors by Jetter AG.
Allow the motor to cool down for some time before you start
working on it, e.g. to carry out maintenance jobs.
If necessary, take additional measures for specific applications
and operating conditions.
DANGER
Hazard caused by high operating voltage!
Risk of electric shock due to wrong grounding of the frame
Wrong grounding can cause a high voltage to be present on the frame.
This may lead to muscle cramps, burns, unconsciousness, respiratory
standstill, or death.
Please mind proper earthing of servo amplifier and servo motor,
such as servo motor.
Please ensure correct, low-resistance grounding of the frame by
PE reference potential in the control cabinet.
The frame must have a conductive, low-resistance connection
with the machine into which the motor has been integrated.
