Special Safety Instructions for the Device

 

Danger to life! Hazardous residual voltage!

After stopping the ignition, there is dangerous residual voltage for up to three minutes in the ignition system. Do not touch any components of the ignition kit during this time.

   

Explosion hazard!

Never open the device (e.g. by removing covers or the service screw). If the system is located in a hazardous area, there is a risk of explosion.

   

Explosion hazard!

The replacement of parts or assemblies can impair compliance with CSA Class I, Division 2 (Group C, D), T4.

   

Explosion hazard!

Do not disconnect any connectors while the system is live. If the system is located in a hazardous area, there is a risk of explosion.

   

Explosion hazard!

Never remove the equipment while the unit is connected to a power source. If the system is located in a hazardous area, there is a risk of explosion.

   

Explosion hazard!

Do not remove or replace the fuse while the equipment is live.

    

Risk of burning!

The surfaces of the system may heat up to high temperatures.

   

Operational safety!

All connector screws and screw joints must be adequately tightened. Refer to the section Mechanical Data.

After the service cover on the device (Light Duty and Heavy Duty Version) has been opened, e.g. to complete the wiring, it must be refitted so that it is in the same alignment as it was prior to opening. The USB connection is then again behind the service screw. If the mounting is rotated, maintaining the indicated protection classes, as well as compliance with CSA-Class I, Division 2 (Group C, D) is impaired.

   

Operational safety

The correct operation of the device is only guaranteed if the device is operated within the permissible supply voltage range. Therefore, use a power supply according to the specifications in the operating instructions.

   

Risk of destruction!

Magnetic fields and heat occur when welding, which may damage or destroy the MIC4. Therefore, pay attention to the following when welding:

  • Disconnect all electrical connections to the MIC4 prior to welding.
  • Protect the MIC4 against direct contact with the welding unit and magnetic fields, sparks and liquid metal.
