Basic Safety Instructions
Danger!
Danger of explosion caused by electrostatic charge!
If there is a sudden discharge from electrostatically charged devices or persons, there is a
danger of explosion in the EX area.
• Take appropriate measures to prevent electrostatic charges in the EX area.
• Clean the device surface by gently wiping it with a damp or antistatic cloth.
Risk of explosion due to adiabatic compression!
Explosive medium and high closing speed create a risk of explosion in the EX area.
• Reduce closing speed.
Media in the EX area:
If explosive media are used, this may create an additional risk of explosions!
Contol unit in the EX area:
The control unit may restrict use in an explosive atmosphere. Follow operating
instructions for controller.
Cleaning in the EX area:
Test cleaning agent for approval in explosive atmosphere.
