7.5.4 Electrical installation
General
WARNING
High electrical voltage! Touching parts with voltages
greater than 50 V can be dangerous to people and lead
to electric shock. When the servo-hydraulic actuator and
the drive controller are operated, certain parts are inevi-
tably under voltage.
−
Mounting, operation and maintenance and/or repairs
of components of the servo-hydraulic actuator and
the drive controller may exclusively be carried out by
Bosch Rexroth or by authorized and qualified per-
sonnel of a specialized company that was authorized
by Bosch Rexroth, see
⮫
Chapter 2.4 “Qualification of
personnel” on page 12.
−
Please observe the general installation and safety reg-
ulations when working on high-voltage systems.
−
Before switching on, the equipment grounding con-
ductor must have been permanently connected to all
electric components in accordance with the connec-
tion diagram.
−
Never operate electrical equipment, even for short-
time measurements or tests, if the protective earthing
conductor is not permanently connected to the points
of the components provided for this purpose.
−
Disconnect the electrical components from the mains
or from the voltage source before accessing parts
with voltages exceeding 50 V. Secure electrical com-
ponents 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 control-
lers to discharge. Measure the electrical voltage of
live parts before beginning work in order to avoid haz-
ards 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.
WARNING
High housing voltage and high working current! Due to
the high housing voltage and the high working current,
touching can lead to electric shocks and severe injuries.
−
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 connection.
