Safety instructions
Bosch Rexroth AG
, Valve amplifier VT-MSPA, RE 30232-B/08.2020
WARNING
High electrical voltage by incorrect connection!
Danger to life, risk of injury due to electric shock.
▶
When carrying out any work, disconnect the relevant machine section from the
power supply and protect it against being switched on again.
▶
Only connect devices, electrical components and cables which feature
protective extra low voltage (PELV) to connections or terminals having voltages
from 0 to 50 Volt.
▶
Only connect voltages and power circuits that feature safe isolation from
dangerous voltages. Safe isolation can be achieved with isolation transformers,
safe optocouplers or mains-free battery operation.
▶
Always connect all cables to the provided connections. Avoid open cables or
contacts.
Lightning!
Risk of uncontrolled machine movements.
▶
An inadequate grounding concept or missing equipotential bonding can lead to
damage to the electronics. Provide for equipotential bonding of the device.
CAUTION
Fault currents and short-circuits!
Impairment of safety and malfunction.
▶
Keep the surroundings free from electrically conductive contamination (acids,
bases, corrosive agents, salts, metal vapors, etc.) and do not expose the device
to these substances. Generally rule out any deposits according to protection
class IP.
2.7 Personal protective equipment
Check determined personal protective equipment for completeness and protective
effect and wear it (observe customer regulations and list of personal protective
equipment).
2.8 Operator‘s obligations
The operation of installations, systems and machines basically requires the
implementation of a holistic IT security concept which is state-of-the-art in terms
of technology. Accordingly, Bosch Rexroth products and their properties must be
considered as components of installations, systems and machines for their holistic
IT security concept.
Unless otherwise documented, Bosch Rexroth products are designed for operation
in local, physically and logically secured networks with access restrictions for
authorized persons, and they are not classified according to IEC 62443-4-2.
