7.7.4 Connecting the power supply
WARNING
Faulty electrical assembly!
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 and any installation work.
Secure the electrical equipment against restarting.
▶
The connection may only be established to an intrinsically safe electric circuit.
For the admissible maximum values and information on electric connection,
see
"Data sheet 29583-XL".
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 proper equipotential bonding.
▶
The 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.
CAUTION
Danger of damage to property and personal injury!
Faulty energy supply may lead to uncontrolled valve movements. These could result
in possible malfunctions or failure of the valve and cause injury.
▶
Always observe country-specific regulations.
Faulty electrical assembly!
Device might be destroyed.
▶
Disconnect the device from the mains or from the voltage source or de-energize
it prior to installation work.
▶
Check the correct assignment of the connection cable braided wires at the
external control electronics.
▶
Ensure that there are no bends in the connection line and braided wires to avoid
short-circuits and interruptions.
▶
For the electrical supply, the mating connector specified in
"Data sheet 29583-XL"
can be used. Mating connectors are available as accessories, see chapter 7.6
"Required accessories".
When selecting the mating connector, observe the safety instructions in this
chapter.
▶
The temperature rating of the lines used must be at least 20 K higher than the
ambient and fluid temperature.
