5.2 fluid installation

Installation position: any, actuator preferably upwards.
Procedure:
→
Prior to installation check pipelines for dirt and clean if necessary.
→
Install a dirt trap to prevent malfunctions (0.2 ... 0.4 mm).
→
Only use new seals.
→
Hold the device with a open-end wrench on the body and screw
into the pipeline.
→
Observe flow direction:
When used in the feed flow: from 1 → 2 (from P → A) or in the
direction of the arrows.
When used in the return flow: from 2 → 1 (from A → P) or in the
opposite direction of the arrows.
note!
Caution risk of breakage!
• Do not use the coil as a lifting arm.
If installed in the wrong direction it can lead to a malfunction of
the firing equipment.
• Observe direction of installation.

▶ Before loosening the pipes and valves, turn off the pressure and
vent the lines.
Risk of injury due to electrical shock!
▶ Before reaching into the device or the equipment, switch off 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 authorized 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.
5.3 electrical connection of the cable plug
Warning!
Risk of injury due to electrical shock!
▶ Before reaching into the system, switch off the power supply and
secure to prevent reactivation.
▶ Observe applicable accident prevention and safety regulations for
electrical equipment.
