7. Information on mounting ... / 8. Safety-related instructions
No capacitor may be fitted within the flameproof 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 off, a waiting time of
2 minutes must be observed before the housing is opened.
EN
Mounting within metallic enclosures:
■
The housing must be grounded against electromagnetic fields and electrostatic
discharge. It does not have to be connected separately to the equipotential bonding
system. It is sufficient 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 modifications are permitted, and any would void the
■
guarantee and the respective certification.
The manufacturer shall not be responsible for constructional modifications after delivery
■
of the instruments.
