Be sure to read before handling.
Maintenance
Warning
1. After installation, repair or disassembly, connect compressed air and conduct tests
to confirm appropriate function and leakage.
Do not use the positioner when noise from the bleeder sounds louder compared with the initial
state, or when it does not operate normally. If these occur, check immediately if assembled and
mounted correctly.
Never modify electrical construction to maintain explosion-proof construction.
Warning-Potential electrostatic charging hazard
1. The non-metallic parts incorporated in the enclosure of this equipment may
generate an ignition capable level of electrostatic charge. Therefore particularly
when it used for applications that specifically require Group IIC, EPL Ga
equipment, the equipment shall not be installed in a location where the external
conditions are conductive to the build-up of electrostatic charge on such surfaces.
Additionally, the equipment shall only be cleaned with a damp cloth.
2. The enclosure contains aluminium and is considered to present a potential risk of
ignition by impact or friction. Care must be taken during installation and use to
prevent impact or friction. Particularly, it must not be used for applications that
specifically require EPL Ga equipment.
Caution
1. The insulation between an intrinsically safe circuit and a frame of the equipment is
not capable of withstanding a 500V dielectric strength test as defined in CI.6.3.12 of
EN 60079-11:2007. This shall be taken into account during installation.
2. the earthing of enclosure is necessary to maintain Intrinsic Safety because the
insulation between an intrinsically safe circuit and a frame of the equipment is not
capable of withstanding a 500V dielectric strength test. There are two earthing
points on the equipment. One is provided as an internal earthing point inside rear
cover of the equipment for attaching of a cable screen. The other is provided as an
external earthing point on the left side of the enclosure. Their cross-sectional areas
should be capable of carrying the maximum possible current of the
equipment.(Generally, an insulated wire having a cross-sectional area of at least
4mm
2
is recommended) The cable should be fitted with a spilt ring lock washer to
minimize the risk of self-loosening and is of suitable construction for securing of
conductors of cross sections up to 4mm
