DANGER!
While the units are in operation there is a risk of death or serious injury
and material damage.
Do not open or touch the units during operation.

Keep all covers and cabinet doors closed during operation.

When the units are switched on, they should only be touched during

commissioning by qualified staff.
During operation the servo amplifiers may contain live, uninsulated

components, depending on their protection type.
Control and power connections may still carry voltage, even when the

motor is not rotating.
Surfaces on the servo amplifiers may become hot during operation.

Temperatures may reach more than 80° C.
DANGER!
In unfavourable conditions arcing may occur, causing potential injury to
persons and damage to electrical contacts.
For this reason, never unplug the electrical connections on the servo

amplifier while voltage is applied.
After disconnecting the servo amplifier from the mains voltages, wait

at least five minutes before touching any parts that carry voltage (e.g.
contacts) or loosening the connections.
After the mains voltages have been switched off, capacitors continue

to carry hazardous voltages for up to 5 min.
To be safe, measure the voltage in the intermediate circuit and wait

until the voltage has dropped below 40 VDC.
