in the ATEX manual or on the respective supplementary sheet.
▶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.
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.

5.6 Installation of coil
WARNING!
Risk of escape of media.
When a sticking nut is loosened, medium may escape.
▶Do not tighten sticking nut any further.
Risk of injury due to electrical shock.
If the protective conductor contact between the coil and body is
missing, there is danger of electrical shock.
▶During installation insert the twist lock (plastic ring) into the body
journal. The plastic ring must not project over the octagonal nipple.
▶Check protective conductor contact after installing the coil.
Overheating, risk of re.
If the coil is connected without a pre-installed valve, the coil will
overheat and be destroyed.
▶Connect the coil with a pre-installed valve only.
