Commissioning, installation

The ABB positioner has to be mounted in a major system.
Depending on the degrees of IP-protection, an interval for
cleaning the equipment (dust settlement) has to be defined.
Strict care has to be taken that only such equipment is installed
that complies with the types of protection relevant to the
applicable zones and categories. When installing the equipment,
the locally applicable rules on erection, e.g. EN 60079-14, have to
be observed.
Other important facts to be observed:
• In all zones, the circuits of the positioner have to be put
into service by a person qualified according to TRBS 1203.
The details on the type label are mandatory for doing this.
• The equipment is constructed for IP 66 and has to be
protected accordingly in adverse ambient conditions.
• The EC-Type Examination Certificates have to be taken
into account including any special conditions defined
therein.
• The equipment shall only be used as intended.
• The equipment is only to be connected when de-
energized.
• The potential equalization of the system has to be
established according to the regulations of erection
applicable in the respective country of use (VDE 0100,
part 540; IEC 364-5-54). For installation according to the
North American Zone concept the external grounding is
supplementary.
• Circulating currents shall not be led via the enclosures!
• It has to be ensured that the enclosure is properly
installed and that its IP protection is not impaired.
• Inside the potentially explosive atmospheres' assembly
shall only be performed taking the locally applicable rules
of erection into account.
The following conditions have to be observed (incomplete):
• Assembly and maintenance to be done only if atmosphere
is Ex-free and a permit for hot works is in place.
• The TZIDC is only to be operated in a fully mounted and
intact enclosure.
