7 ASSEMBLY AND DISASSEMBLY
7.1 Safety instructions
DANGER!
Risk of explosion!
Following installation, solenoid coil and valve body form a closed
system. If used in the explosion-risk area, there is a danger of
explosion if the system is opened during operation!
▶ The system must not be disassembled during operation.
Risk of short-circuit!
Damaged connection lines may cause a short-circuit.
▶ The connection lines for the coil must be laid permanently and
protected against damage.
Risk of burns/risk of fire during long-term operation!
The solenoid coil may become very hot during long-term operation.
▶ Take hold of a device which has been running for a prolonged
period with protective gloves only.
DANGER!
Risk of electric shock!
There is a serious risk of injury when reaching into the equipment.
▶ Live terminals in the terminal box may cause an electric shock,
short-circuit or explosion. Switch off the power supply. Only then
open the terminal box.
▶ The connection lines of the electromagnets must be permanently
installed in such a way that they are adequately protected from
mechanical damage.
▶ Only trained electrical engineers may work on the electrical system.
▶ Before starting work, always switch off the power supply and
safeguard to prevent re-activation!
▶ Observe applicable accident prevention and safety regulations
for electrical equipment!
WARNING!
Danger – high pressure!
When reaching into the system, there is an acute risk of injury.
▶ Only skilled and instructed personnel may work on the system
with suitable tools.
▶ Before disconnecting lines and valves, switch off the pressure
and bleed the lines.
▶ Observe applicable accident prevention and safety regulations
for pressurized devices.
▶ After an interruption in the power supply or fluid supply, ensure
that the process is restarted in a defined or controlled manner.
▶ During installation note the flow direction.
DANGER!
▶ The operator must ensure an adequate strain relief.
▶ Lines with an outer diameter of 6 mm ... 13 mm can be used.
Observe the maximum thermal load of the installed cables and
lines.
▶ The inserted break-out seal must be adjusted to the diameter of
the cable/line.
▶ The rated cross-section of the cables/line cores must be at least
0.75 mm² and must not exceed 2.5 mm².
▶ Screws for attaching the cover of the terminal box must be tight-
ened to a torque of 100 Ncm (±5%).
