Entity Requirement 8.8
Cable capacitance and inductance plus the I.S. apparatus unprotected
capacitance (Ci) and inductance (Li) must not exceed the allowed capacitance
(Ca) and inductance (La) indicated on the associated apparatus. If the optional
Hand Held Communicator is used on the Hazardous Area side of the barrier, then
the capacity and inductance of the communicator must be added and the
communicator must be agency approved for use in the hazardous area. Also,
the current output of the Hand Held Communicator must be included in the
current output of the associated equipment.
For North American installations, the barriers may be active or passive and from
any FM Approved manufacturer as long as the barriers comply with the listed
entity parameters.
For European installations, the barriers may be active or passive and from any
certified manufacturer as long as the barriers comply with the listed entity
parameters and are installed per the guidelines of EN60079-14.
For other international installations, the barriers may be active or passive and
from any certified manufacturer as long as the barriers comply with the listed
entity parameters and are installed per the guidelines of IEC60079-14.
If the electrical parameters of the cable used are unknown, the following values
may be used: Capacitance – 197pF/m (60 pF/ft), Inductance – 0.66 μH/m (0.20
μH/ft).
Use in dust atmosphere 8.9
Dust-tight conduit seal must be used when installed in dust hazard
environments.

REPAIR
WARNING: EXPLOSION HAZARD – SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY
FOR USE IN A HAZARDOUS LOCATION.
Only qualified service personnel are permitted to make repairs on the SVI FF positioner.
Replace ONLY with genuine GE parts.
Use only cover bolts of Autenitic Grade A2 Class 70 or Grade A4 Class 70, supplied by the
manufacturer.
Consult the manufacturer for dimensional information on the flameproof joints for repair.
Only parts supplied by GE are permitted. This includes not only the major assemblies but
also mounting screws and “O” rings. No substitutions with non-GE parts are permitted.
