DANGEr
Voltage at the terminals and in the motor !
Danger to life due to electric shock!
► Never work on the open motor or never touch exposed parts.During
the operation (even at zero speed) the motors posses dangerous
live parts.
► For any work on the motor switch off the supply voltage and secure
it against switching on.
► Wait until the drive has stopped in order that no regenerative energy
can be generated.
► Never bridge upstream protective devices (also not for test pur-
poses).
► Connect the protective earth conductor to drive converter and motor.
► Install all required covers and protective devices for operation.
For a trouble-free and safe operation, please pay attention to the following instructions:
• The electrical installation shall be carried out in accordance with the relevant re-
quirements.
• The motors are not designed for direct connection to the three-phase system but are
to be operated via an electronic power inverter.
• Connect the temperature sensor to protect the motor against slow thermal chang-
es. Temperature sensors do not represent an all-around protection of the winding.
Measures must be taken in the parameterisation of the inverter for the protection
against fast thermal changes (e.g. I2´t-monitoring) !
• Check the proper functioning of the brake (optional).
• An optional holding brake is only designed for a limited number of emergency brak-
ings. Never use it as a working brake.On motors with plug connector and built-in
brake, it is the user's responsibility to install the varistor provided to control the
brake.
Installations which include drive converter shall be equipped with additional control and
protective devices in accordance with the relevant applicable safety requirements, e.g.
act respecting technical equipment, accident prevention rules etc. They must always be
complied with, also for drive converter bearing a CE marking.
