Protection against electrostatic discharges

DANGER
Risk of explosion!
The painted surface of the device can store electrostatic
charges. As a result, the housing can form an ignition source
due to electrostatic discharges in the following conditions:
— The device is operated in environments with a relative
humidity of ≤ 30 %.
— This painted surface of the device is therefore relatively
free from impurities such as dirt, dust or oil.
The instructions on avoiding the ignition of hazardous areas
due to electrostatic discharges in accordance with the
EN TR50404 and IEC 60079-32-1 standards must be
observed!
