Note 2. Wiring
• In hazardous locations, the cable entry
devices shall be of a certified flameproof
type, suitable for the conditions of use and
correctly installed.
• Unused apertures shall be closed with
suitable flameproof certified blanking
elements.
Note 3. Operation
• WARNING:
AFTER DE-ENERGIZING, DELAY 5
MINUTES BEFORE OPENING.
• WARNING:
WHEN AMBIENT TEMPERATURE ≥65ºC,
USE THE HEAT-RESISTING CABLES AND
CABLE GLAND ≥ 90ºC.
• Take care not to generate mechanical
sparking when accessing to the instrument
and peripheral devices in a hazardous
location.
• 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.
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 IECEx
Certification.
• Electrical Connection
A mark indicating the electrical connection
type is stamped near the electrical
connection port. These marks are as follows.
