2.6 Product- and technology-dependent safety instructions for
Rexroth tightening system 350
2.6.1 Protection against accidental contact with electrical parts
Contacting parts with voltages greater than 50 V can be dangerous to persons and lead to electric shock.
When electrical devices are operated, specific parts of these devices are under a dangerous voltage.
This section only applies to devices and components with voltages above 50 V.
DANGER
High voltage!
Danger to life, risk of injury due to electric shock, or risk of serious injury!

This device may only be operated, maintained and/or repaired by personnel trained and qualified
to work on or with electrical devices.

Observe the general construction and safety regulations for working with high-voltage systems.

Firmly connect the protective conductor to all electrical devices according to the connection
diagram before switching the system on.

Operation, even briefly for measuring or testing purposes, is only permitted if the protective
conductor is firmly connected to the components at the intended points.

Disconnect the device from the mains or voltage source before accessing electrical parts with
voltages greater than 50 V. Protect it against being switched on again.

After switching off the power supply, wait 10 seconds for the system to discharge before opening
the housing or starting repair/maintenance work.

For electrical drive and filter components:
After switching off, take the specified discharging time for the respective components into
account before accessing the devices. To eliminate the risk of contact, measure the voltage of
the condensers before starting work.

Do not touch the electrical connection points of the components when the device is switched on.

Before switching on, attach the provided covers and protective devices (protection against
accidental contact) to the devices. Also, before switching on, securely cover and protect live
parts to prevent accidental contact.

Do not touch the electrical connection points of the components when the device is switched on.

A residual-current-operated protective device (RCD) cannot be used for multi-channel tightening
systems! Protection against accidental contact must be ensured by other means, for example via
an overload protection device corresponding to the relevant standards.

Prevent accidental contact with electrical parts in installed devices by means of an external
housing such as a switch cabinet.

Before using the system or starting service/maintenance work, make sure you read and
understand these operating instructions.
European countries: Corresponding to EN 50178/1998, paragraph 5.3.2.3.
USA: See National Electrical Code (NEC), National Electrical Manufacturers Association (NEMA), as
well as regional building codes.
The operator must comply with all of the above points at all times.
