RE 29681-B/11.2019; VT-SVTSY-1-1,
Bosch Rexroth AG
WARNING
High electrical voltage by incorrect connection!
Danger to life, risk of injury by electric shock!
▶
The test device may only be connected by or under the supervision of a
specialized electrician.
▶
Switch off the power supply before any work, during which the test device is
installed in the system, and secure it against restarting.
▶
Provide for proper, safe PE connection.
▶
Provide the supply voltage according to VDE0100 part 410.
▶
For the external voltage supply, it must be ensured that, even in the event of
a fault, the voltage limits defined for the test device are not exceeded. PELV
power supply units according to EN 60204, section 6.4.2 comply with these
requirements.
▶
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, for example.
▶
Use exclusively the cables and leads contained in the test case for
interconnecting the test device in the valve control cable.
Missing equipotential bonding!
Electrostatic processes, an incorrect earthing concept or missing equipotential
bonding may lead to malfunctions or uncontrolled movements at the machine and
thus cause injuries.
▶
Provide for correct earthing and provide for proper equipotential bonding
when you connect the device in the machine.
Penetrating water and humidity!
In case of use in humid or wet environments, water or humidity may penetrate
at electrical plug-in connectors or the valve electronics. This case may lead to
malfunctions at the test device and to unexpected movements in the hydraulic
system which may result in personal injury and damage to property.
▶
Only use the test device within the intended IP protection class or lower.
▶
Ensure before the installation that all seals and caps of the plug-in
connections are present and intact.
CAUTION
Exceedance of the maximum temperatures!
Use of the test device outside the intended temperatures may lead to functional
failures. In the worst case, this may result in unexpected system movements and
thus constitute a risk of injury.
▶
Only use the test device within the ambient temperatures provided for it.
