(flange version) or central fixing G 1/8 (plugged-on version).
They may be disassembled only by the manufacturer!
The valves always represent a closed system.

DANGER!
Risk of explosion!
• Only permanently laid cables and wiring may be inserted.
• The operator must provide suitable stress relief.
• Wires with an outside diameter of 6 to 13 mm may be used. Observe
the maximum thermal loading of the cables or wires to be inserted.
• The inserted break-off seal must be matched to the diameter of the
cable or wire.
• The rated cross-section of the cable or wire strands must be at least
0.75 mm² and may not exceed 2.5 mm².
• The screws for fixing the cover of the terminal box must be tightened
with a torque of 100 Ncm (±5%).
The solenoid coils may also be executed with a terminal box, with or without fuse/
contactor (to separate Design Inspection Certificate) as desired.
For protection against inadvertent opening of the cover, the latter bears the marking:
Open only when the voltage is switched off!
