WARNING
Terminals and connections have voltage even in a unit that is
shut off
Electric shock
➜ Wait five minutes after disconnecting the voltage at all poles
CAUTION
If control voltage is applied or a speed setpoint is stored,
the motor automatically restarts, e.g. after a power failure.
Danger of injury
Keep out of the danger zone of the device.
➜ When working on the device, switch off the mains supply voltage
➜ Wait until the device stops.
If the device remains out of use for some time, e.g. when in storage,
we recommend switching the device on for at least 2 hours to allow
any condensate to evaporate and to move the bearings.
If you have any other problems, contact ebm-papst.
