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!
