7.6.4 Electrical installation
General
High electrical voltage!
Touching parts with voltages greater than
50 V can be dangerous to people and lead to
electric shock. During operation of the self-
contained servo-hydraulic linear axis and the
drive controller certain parts are inevitably un‐
der voltage.
WARNING
● Mounting, operation and maintenance and/or repairs of components of
the self-contained servo-hydraulic linear axis and the drive controller
may exclusively be carried out by Bosch Rexroth or by authorized and
qualified personnel of a specialized company that was authorized by
Bosch Rexroth, see chapter 2.4 "Qualification of personnel" on page
10 .
● Please observe the general installation and safety regulations when
working on high-voltage systems.
● Before switching on, the equipment grounding conductor must have
been permanently connected to all electric components in accordance
with the connection diagram.
● Never operate electrical equipment, even for short-time measurements
or tests, if the protective earthing conductor is not permanently connec‐
ted to the points of the components provided for this purpose.
● Disconnect the electrical components from the mains or from the volt‐
age source before accessing parts with voltages exceeding 50 V. Se‐
cure electrical components against restarting.
● After switching off, you should generally wait for 30 minutes before you
touch an electrical component in order to allow the live capacitors in the
drive controllers to discharge. Measure the electrical voltage of live parts
before beginning work in order to avoid hazards caused by contact.
● Before switching on, attach the covers and protective devices provided
for contact protection.
● Do not touch the electrical connection points of the components when
the system is activated.
● Do not disconnect or connect the connectors under voltage.
High housing voltage and high working cur‐
rent!
Due to the high housing voltage and the high
working current, touching can lead to electric
shocks and severe injuries.
WARNING
● Connect the equipment grounding conductor of the components of the
electric drive and control system permanently to the main power supply
at all times. The leakage current is greater than 3.5 mA.
● Observe the minimum cross-section of the protective earthing connec‐
tion.
