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 33 to page 34.
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 33 to
page 33. 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.

2.5 mm or
– Direct connection of fine wires of up to 1.5 mm
– Connection of cross-sections of up to 6 mm
ring or spade terminal with 4 mm drill hole.
• For proper selection of cables see electrical installation
instructions in the original manufacturer's manual. Use
cables rated at least 20 K greater than the ambient
temperature.
• High / recurring charging processes in gas areas must be
excluded by the operator.
Notes for operation
• The positioner shall be included in the local equipotential
bonding system
• Either only intrinsically or non intrinsically safe circuits shall
