WARNING: AFTER DE-ENERGIZING,

DELAY 5 MINUTES BEFORE OPENING.

WHEN THE AMBIENT TEMP.≥65°C, USE

HEAT-RESISTING CABLE AND CABLE

GLAND≥90°C.

• Take care not to generate mechanical

sparking when accessing the instrument and

peripheral devices in hazardous location.

Note 5. Special Conditions for Safe Use

WARNING

• Electrostatic charge may cause an exlosion

hazard. Avoid any actions that cause the

gerenation of eletrostatic 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 aluminium,

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.

• The instrument modification or parts

replacement by other than an authorized

Representative of Yokogawa Electric

Corporation is prohibited and will void the
