2.1 General safety instructions
WARNING
Electric shock and danger to life due to other energy sources
Touching live components can result in death or serious injury.
•Only work on electrical devices when you are qualified for this job.
•Always observe the country-specific safety rules.
Generally, the following steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be affected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specified on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any of
the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other hazardous energy sources, e.g. compressed air, hydraulic systems, water.
Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness in the inverse
sequence.
WARNING
Electric shock if there is no ground connection
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when
touched, can result in death or severe injury.
•Ground the device in compliance with the applicable regulations.

Fundamental safety instructions
2.1 General safety instructions
Air-Cooled Chassis Power Units - supplement to Motor Module 6SL3320-1TG41-5AA3
14 Equipment Manual, 10/2020, A5E50422764A
WARNING
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may
carry a hazardous voltage that might result in serious injury or death.
•Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV-
(Protective Extra Low Voltage) output voltages for all connections and terminals of the
electronics modules.
WARNING
Electric shock due to equipment damage
Improper handling may cause damage to equipment. For damaged devices, hazardous
voltages can be present at the enclosure or at exposed components; if touched, this can
result in death or severe injury.
•Ensure compliance with the limit values specified in the technical data during transport,
storage and operation.
•Do not use any damaged devices.
WARNING
Electric shock due to unconnected cable shield
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
•As a minimum, connect cable shields and the cores of power cables that are not used
(e.g. brake cores) at one end at the grounded housing potential.
WARNING
Arcing when a plug connection is opened during operation
Opening a plug connection when a system is in operation can result in arcing that may
cause serious injury or death.
•Only open plug connections when the equipment is in a voltage-free state, unless it has
been explicitly stated that they can be opened in operation.
WARNING
Electric shock due to residual charges in power components
Because of the capacitors, a hazardous voltage is present for up to 5 minutes after the
power supply has been switched off. Contact with live parts can result in death or serious
injury.
•Wait for 5 minutes before you check that the unit really is in a no-voltage condition and
start work.
