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 %.
• The painted surface of the device is thereby relatively free
from impurities such as dirt, dust or oil.
• Instructions on avoiding ignition in potentially explosive
environments due to electrostatic discharges in
accordance with PD CLC/TR 60079-32-1 and IEC TS 60079-
32-1 must be complied with!
Instructions on cleaning
The painted surface of the device must be cleaned only using a
moist cloth.
Devices which are approved for use in potentially explosive
atmospheres have an additional warning plate.
1 WARNING! – Danger due to electrostatic discharge.

Repair

Devices of type of protection 'd' are equipped with flameproof
joints in the housing. Contact ABB before commencing repair
work.
