The device is a closed system. It must not be removed.
The following safety instructions must be observed:
• The surface of the device may become electrostatically charged.
In potentially explosive areas the surface of the devices may be
cleaned with a damp or an anti-static cloth only.
• Only specified cables and lines may be used.
• 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 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
tightened to a torque of 100 Ncm (± 5 %).
Danger!
risk of electric shock!
Acute risk of injury from hazardous body voltage! Risk of damaging
the device by short-circuit!
• Before reaching into the device or the equipment, switch off the
power supply and secure to prevent reactivation!
• 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.
• 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.
