ABB TZIDC-210 Operating Instructions Manual page 25

TZIDC-210, TZIDC-220 DIGITAL POSITIONER | OI/TZIDC-210/TZIDC-220-EN REV. G
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-210, TZIDC-220 is only to be operated in a fully
mounted and intact enclosure.
• Outside of the housing is a connector for the
equipotential bonding.
The following opportunities are available:
– Direct connection of single-strand wires of up to
2
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
be connected. A combination is not permitted.
• When the Positioner is operated with non intrinsically safe
circuits, the subsequent use for type of protection Intrinsic
Safety is not permitted.
Special conditions for the safe use of intrinsically safe
positioners
Special conditions
• The 'Local communication interface (LCI)' may only be used
outside of the explosion hazardous area with U
• Measures of lightning protection have to be provided by the
user.
Special conditions for safe use of Positioners non I.S.
• Only devices which are suitable for the operation in explosion
hazardous areas declared as zone 2 and the conditions
available at the place of operation are allowed to be
2
or
connected to circuits in the zone 2.

• The connecting and disconnecting as well as the switching of
circuits under voltage are only permitted during installation,
for maintenance or repair purposes.
Note
The temporal coincidence of explosion hazardous atmosphere
and installation, maintenance resp. repair purposes is assessed
as improbably.
• For the circuit 'Position feedback with proximity switches or
microswitches' measures have to be taken outside the device
that the rated voltage is exceeded not more than 40 % by
transient disturbances.
• Only non combustible gases are allowed to be used as
pneumatic auxiliary energy.
• Only suitable cable entries which meet the requirements of
IEC 60079-15 are allowed to be used.
Use, operation
The TZIDC-210, TZIDC-220 is only approved for intended and
appropriate use. In case of non-compliance, the warranty and
manufacturer's liability do no longer apply!
• In explosive atmospheres only such auxiliary components
shall be used that meet all requirements of the European and
the national standards.
• The ambient conditions specified in the instruction manual
have to be adhered to strictly.
• The TZIDC-210, TZIDC-220 has only been approved for its
appropriate and intended use in standard industrial
atmospheres. Where aggressive substances are present in
the air, the manufacturer has to be consulted.
