5 safety rules
1. Disconnect the system.
Also disconnect the auxiliary circuits, for example, anti-condensation heating.
2. Secure against reconnection.
3. Verify absence of operating voltage.
4. Ground and short-circuit.
5. Provide protection against adjacent live parts.
To energize the system, apply the measures in reverse order.
2.4
Safe handling
Electric shock from external supplies
Even if the circuit breaker is open, parts of the drive can be under voltage (live) as a result of
the auxiliary voltage at the premagnetization, precharging or demagnetization transformers.
This danger is not limited to the drive, but can also occur with components that are electrically
connected to the drive (e.g. circuit breakers or isolators). Touching live parts can result in death,
serious injury and material damage
● Isolate all components that can feed voltage to the drive before commencing work.
Electric shock due to high voltages in operation
When operating this equipment very high voltages develop. Even after switching off the mains
voltage, or while the connected machine is still turning, high voltages can remain for a
prolonged length of time. Touching live parts can result in death or serious injury.
● Carefully comply with the 5 safety rules (Page 13).
● Operate the device properly.
● Service and maintain the device regularly and correctly.
Electric shock caused by induced voltage
Rotating machinery can induce dangerous high voltages and synchronous motors that are not
de-excited immediately can also pose a hazard. If the connection to the motor is not isolated or
grounded, these voltages can also remain. Touching live parts can result in death or serious
injury.
● Before opening the doors, wait until the connected machine has come to a standstill.
