■

No capacitor may be tted within the ameproof enclosure that has a residual energy of

≥ 0.02 mJ at the end of the time required to open the housing. The housing must not be

opened during operation. After the power supply has been switched o, a waiting time of

2 minutes must be observed before the housing is opened.

■

Mounting within metallic enclosures:

The housing must be grounded against electromagnetic elds and electrostatic

discharge. It does not have to be connected separately to the equipotential bonding

system. It is sucient if the metallic thermowell has a solid and secured contact with the

metallic vessel or its structural components or pipelines, so long as these components are

connected to the equipotential bonding system.

■

Mounting within non-metallic enclosures:

All electrically-conductive thermometer components within the hazardous area must be

provided with equipotential bonding.

■

Neither repairs nor structural modications are permitted, and any would void the

guarantee and the respective certication.

■

The manufacturer shall not be responsible for constructional modications after delivery

of the instruments.
