surface resistance.
Ground connection
Fig. 7: Ground connection
Only devices for operation in potentially explosive areas with combustible, Zone
22 – Dry dusts have an earth connection on the left-hand side.
The housing is made of a non-conductive plastic. To reduce its surface resist-
ance, a metal layer has been applied in an evaporation process. To discharge
any static charging (e.g. caused by wiping), the housing must be earthed.
