General hazardous situations.

To prevent injury, ensure that:

▶Do not make any internal or external changes. Ensure that the sys-

tem cannot be activated unintentionally.

▶Installation and repair work may be carried out by authorized tech-

nicians 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.

▶For models with ATEX or UL approval follow the safety instructions

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.

DANGER!

Risk of injury from high pressure in the equipment.

▶Before loosening the pipes and valves, turn o the pressure and

vent the lines.

Risk of injury due to electrical shock.

▶Before reaching into the device or the equipment, switch o the

power supply and secure to prevent reactivation.

▶Observe applicable accident prevention and safety regulations for

electrical equipment.

WARNING!

Risk of injury from improper installation.

▶Installation may be carried out by authorised technicians only and

with the appropriate tools.

Risk of injury from unintentional activation of the system and an

uncontrolled restart.

▶Secure system from unintentional activation.

▶Following assembly, ensure a controlled restart.

5.2 Before installation

shock.

▶Always connect protective conductor and check electrical

continuity.

Seal

50 – 60 Ncm

Approved cable plug,

e.g. Type 2518 or other suitable cable plug in

accordance with DIN EN 175301-803 Form A

english

→Tighten cable plug (for permitted types see data sheet), observing

max. torque 50-60 Ncm.

→Check that seal is tted correctly.

→Connect protective conductor and check electrical continuity.

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.
