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, have to be observed, see
Page 4 of 5 on page 38 to
Page 5 of 5 on page 39.
Other important facts to be observed:
• The equipment is constructed for IP 66 and has to be
protected accordingly in adverse ambient conditions.
• The 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, see
Page 4
of 5 on page 38 to Page 4 of 5 on page 38 . 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.
