(3) Maintenance and repair
WARNING
The instrument modification or parts replacement
by other than an authorized representative of
Yokogawa Electric Corporation is prohibited and
will void the certification.
• A modification of the equipment would
no longer comply with the construction
described in the certificate documentation.
• Only personnel authorized by Yokogawa
Electric Corporation can repair the
equipment
• USE ONLY YOKOGAWA BATTERY PACK
F9090FC or F9090GC
• THE BATTERY PACK CAN BE REPLACED
IN A HAZARDOUS LOCATION. THE
BATTERY PACK HAS SURFACE
RESISTIVITY GREATER THAN 1G OHM
AND MUST BE PROPERLY INSTALLED IN
THE ENCLOSURE OF THE EQUIPMENT.
CARE MUST BE TAKEN DURING
TRANSPORTATION TO AND FROM THE
POINT OF INSTALLATION TO PREVENT
ELECTROSTATIC CHARGE BUILD-UP
• CELLS MUST BE CHANGED IN A NON-
HAZARDOUS AREA ONLY
• SUBSTITUTION OF COMPONENTS MAY
IMPAIR INTRINSIC SAFETY
2.7 EMC Conformity Standards
EN61326-1 Class A Table 2, EN55011 Class A
CAUTION
This instrument is a Class A product, and it is
designed for use in the industrial environment.
Please use this instrument in the industrial
environment only.
2.8 Safety Requirement
Standards
Applicable standard:
EN61010-1, CAN/CSA-C22.2 No.61010-1
(1) Pollution Degree 2
“Pollution degree” describes the degree to which
a solid, liquid, or gas which deteriorates dielectric
strength or surface resistivity is adhering. “2”
applies to normal indoor atmosphere. Normally,
only non-conductive pollution occurs. Occasionally,
however, temporary conductivity caused by
condensation must be expected.
(2) Installation Category I
“Overvoltage category (Installation category)”
describes a number which defines a transient
overvoltage condition. It implies the regulation for
impulse withstand voltage. “I” applies to electrical
equipment which is supplied from the circuit when
appropriate transient overvoltage control means
(interface) are provided.
(3) Indoor/Outdoor use
It can be used in indoors and outdoors.
(4) Altitude of installation site
Max. 3,000 m above sea level
