5.5.2 Order of connection
When connecting or disconnecting the servo motor, the following safety guidelines and orders must be observed.
Danger!
Risk of injury due to electric shock!
If live parts are touched, there is immediate danger of fatal electric shock.
If connections are connected or disconnected in the wrong order or when the power is switched on,
electric arcs can occur and persons and contacts can be damaged.
Even if the motor is not rotating or is running as a generator driven externally, the control and power
connections can still carry voltage!
•
Never touch connections when the power is switched on.
•
Never disconnect or connect electrical connections to the motor and servo drive when the
power is switched on!
•
Do not stay in the danger zone during operation and secure it against access by unauthorized
persons.
•
Always operate the motor with all safety equipment. Do this even during short testing and trial
operations!
•
Keep all covers and control cabinet doors closed during operation and as long as the machine
is not disconnected from the power system.
•
Before working on motors, gearboxes or servo drives or in the danger zone of your machine,
disconnect them completely from the power system and secure them against being switched
on again by other persons or automatic systems.
•
Note the discharge time of any existing DC bus.
•
Only connect measuring instruments when the power is switched off!
Danger!
After switching off the servo drive, wait for the DC bus to discharge for at least five minutes. To avoid
a hazard, the current voltage on the DC bus must be measured between -DC1 and +DC1 and less than
42 VDC before starting work with a suitable measuring instrument. An unlit operating LED does not
indicate that the device is de-energized!
Caution!
The temperature sensor on the motor is sensitive to electrostatic discharge (ESD). For this reason,
the attachment cables on the drive system side (ACOPOS) must first be completely assembled and
connected. Only then are the connectors permitted to be connected to the motor in the order described.
