Note: Only relevant for devices and drive components with voltages
exceeding 50 volts.
Coming into contact with components carrying voltages greater than 50
volts can be dangerous. Certain parts are under dangerous voltage when
operating electrical devices.
High Voltage!
Danger to life or risk of bodily injury!
⇒ Follow general construction and safety regulations
when working on electrical installations.
DANGER
⇒ Before switching on power, be sure that the ground
wire is permanently connected to all electrical units
according to the connection diagram.
⇒ At no time may electrical equipment be operated if the
ground wire is not permanently connected to the
proper terminals, even for brief measurements or
tests.
⇒ Disconnect the equipment from the power supply line
or the voltage source before beginning work. Secure
equipment from reclosure.
⇒ Wait 5 minutes after switching off power to allow ca-
pacitors to discharge before using the equipment.
Measure the voltage of the capacitors before begin-
ning work in order to eliminate dangers arising from
touching components.
⇒ Never touch the electrical connection points of a com-
ponent while the power is turned on.
⇒ Cover live parts properly before switching the equip-
ment on so they cannot be touched. Covers provided
with the equipment must be installed before operating
the equipment to prevent contact with live parts. The
equipment may only be operated with the covers de-
signed for shock-hazard protection.
⇒ A GFCI protective device (ground fault circuit inter-
rupter) cannot be used for AC drives! Protection
against indirect contact must be ensured by other
means, for example, by using an overcurrent protec-
tion device in accordance with relevant standards.
European countries: in accordance with EN 50178/
1994, section 5.3.2.3
⇒ For installation equipment protection against indirect
contact must be ensured using an external housing,
such as a control cabinet. European countries: in ac-
cordance with EN 50178/1994, section 5.3.2.3
