Risk of injury due to malfunction of valves with alternating
current (AC)!
Sticking core causes coil to overheat, resulting in a malfunction.
▶Monitor process to ensure function is in perfect working order!
Risk of short-circuit/escape of media through leaking screw joints!
▶Ensure seals are seated correctly.
▶Carefully screw valve and connection lines together.
General hazardous situations.
To prevent injury, ensure that:
▶Do not make any internal or external changes. Ensure that the
system cannot be activated unintentionally.
▶Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
▶After an interruption in the power supply or pneumatic supply,
ensure that the process is restarted in a dened or controlled
manner.
▶Do not put any loads on the body.
▶The general rules of technology apply to application planning
and operation of the device.
3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any contingencies
and events which may arise during installation, operation and
maintenance.
Danger – high pressure!
▶Before loosening the lines and valves, turn o the pressure and
vent the lines.
Risk of electric shock!
▶Before reaching into the system, switch o the power supply
and secure to prevent reactivation!
▶Observe applicable accident prevention and safety regulations
for electrical equipment!
Risk of burns/Risk of re if used continuously through hot device
surface!
▶Keep the device away from highly ammable substances and
media and do not touch with bare hands.
