If it is possible that static electricity can cause hazards in the measurement environment,
equipotential bonding must be attended according to the regulations concerning potentially
explosive atmospheres. Equipotential bonding is done by connecting all conductive parts to
the same potential e.g. in a junction box. Equipotential bonding system must be grounded.
The instructions concerning the inspection and maintenance of Ex equipment contained in
the standards IEC/EN 60079-17 and IEC/EN 60079-19 should be observed when
executing service, inspection or repair procedures in potentially explosive atmospheres.
