Voltage at the terminals and in the motor !
Danger to life due to electric shock!
►
Never work on the open device or 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 perhaps 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 with additional safety or protective measures in accordance with their re-
quirements have to be checked, when using drive converters, to be in accordance with
the given application notes or recommendation when using these!
