Note 4. Battery Pack
• Use only YOKOGAWA battery pack
F9090FC or F9090GC.
WARNING
• Be sure to use the specified battery pack
and batteries. For details, refer to section 8.5
“Handling Batteries.”
• With an intrinsically safe Products, the
battery pack is replaceable in a hazardous
area. During the replacement work, make
sure that dust and water droplets do not
enter inside the Products. For details on how
to replace the battery pack, refer to section
8.3 “Replacing the Battery Pack.”
Note 5. Specific conditions of use
• Precaution shall be taken to minimize the risk
from electrostatic discharges on the non-
metallic parts of the equipment.
• The connector (FN110 terminal) on the
enclosure contains aluminum and is
considered a potential risk of ignition caused
by impact or friction. When the equipment
is mounted in a potentially explosive
atmosphere requiring Equipment Category
1 G, it shall be installed in such a way that,
even in the event of rare incidents, an ignition
source due to impact and/or friction sparks is
excluded.
(2) Operation
WARNING
Take care not to generate mechanical sparking
when access to the instrument and peripheral
devices in a hazardous location.
POTENTIAL ELECTROSTATIC CHARGING
HAZARD
In hazardous areas, avoid any actions which
generate electrostatic charges, such as rubbing
the equipment with a dry cloth.
To prevent electrostatic discharge caused by
static charge built up on the operator, ground the
operator through conductive shoes and floors
and by wearing antistatic work clothes to prevent
charge build-up.
Avoid any actions that cause the generation of
electrostatic charge, such as rubbing surface of
Battery Pack and product with a dry cloth.
If static electricity cannot be suppressed, check
that the surrounding atmosphere does not
contain explosive gas or steam before replacing
the Battery Pack.
