7.7.3 Connecting the power supply
High electrical voltage!
Danger to life, risk of injury caused by electric shock due to incorrect connection
and faulty pin assignment.
▶
The valve may only be connected by or under the supervision of a specialized
electrician.
▶
De-energize and depressurize the system before the assembly, pulling and
connecting plug-in connectors and all other installation works. Secure the
electrical equipment against restarting.
▶
Provide for proper, safe PE connection.
▶
Check before switch-on whether the protective grounding conductors at all
electric devices are firmly connected according to the connection diagram.
▶
After connection, re-attach the cover so that it cannot be lost.
Explosion hazard due to lack of equipotential bonding!
Electrostatic processes, an incorrect grounding concept or a lack of equipotential
bonding may lead to an explosion. Apart from this, malfunctions or uncontrolled
movements at the machine may be caused!
▶
Provide for correct grounding and provide for proper equipotential bonding.
▶
The base plate or subplate on which the valve is fitted must be electrically
conductive and included in the equipotential bonding according to EN 60079-14
and IEC 60364-4-41.
Explosion hazard due to improper installation!
No precautions are taken for safe connection of the shielding or sheathing in the
terminal box of the valve solenoid and on the cable and line entry. The use of
connection lines with shielding or sheathing can lead to potential backfeeding and
is thus an explosion hazard!
▶
Only use connection lines without shielding or sheathing.
Danger of damage to property and personal injuries!
Faulty energy supply may lead to uncontrolled valve movements. These could result
in possible malfunctions or failure of the valve and cause injuries.
▶
Only use a power supply unit with safe separation.
▶
Always observe country-specific regulations.
Danger of short circuit caused by missing seals and caps!
Fluids may enter the valve and cause a short-circuit.
▶
Before commissioning, ensure that all seals and caps of the plug-in connections
are leak-proof.
