7.7.3 Establishing the electrical connection
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 the system before the assembly, pulling and connecting plug-in
connectors and all other installation works. Secure the electrical equipment
against restarting.
▶
The valve solenoid may only be connected to an intrinsically safe electric circuit
with the safety-related maximum values specified in "Data sheet 23177-XH".
▶
Do not operate the valve solenoid with AC voltage.
Explosion hazard due to missing equipotential bonding!
Electrostatic processes or a missing equipotential bonding may lead to an explosion.
Apart from this, malfunctions or uncontrolled movements at the machine may be
caused!
▶
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 caused by improper assembly (at version Z2 only)!
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.
