Note 3. Installation
• All wiring shall comply with local installation
requirements. (Refer to the installation
diagram)
Note 4. Maintenance and Repair
• The instrument modification or parts
replacement by other than authorized
representative of Yokogawa Electric
Corporation is prohibited and will void
DEKRA Intrinsically safe Certification.
Note 5. Special Conditions for Safe Use
WARNING
• In the case where the enclosure of the
Pressure Transmitter is made of aluminium,
if it is mounted in an area where the use of
category 1 G apparatus is required, it must
be installed such, that even in the event of
rare incidents, ignition sources due to impact
and friction sparks are excluded.
• Electrostatic charge may cause an explosion
hazard. Avoid any actions that cause the
generation of electrostatic charge, such as
rubbing with a dry cloth on coating face of
the product.
• In the case where the enclosure of the
Pressure Transmitter is made of aluminum,
if it is mounted in an area where the use of
category 2D apparatus is required, it shall
be installed in such a way that the risk from
electrostatic discharges and propagating
brush discharges caused by rapid flow of
dust is avoided.
• To satisfy IP66 or IP67, apply waterproof
glands to the electrical connection port.
• When the lightning protector option is
specified, the apparatus is not capable
of withstanding the 500V insulation test
required by EN60079-11.
This must be taken into account when
installing the apparatus.
