1.4 Precautions for Installation
Area
To use the converter stably for a long time,
determine an installation place, taking into account
the following.
(1) Ambient Temperature
Avoid installing the instrument in a place subject
to a large temperature gradient and variations.
If the instrument is subject to plant-generated
heat radiation, take measures such as provision
of heat protection and good ventilation.
(2) Atmospheric Conditions
Avoid installing the converter in corrosive
atmosphere.
Should it be used in corrosive atmosphere,
make provision for maintaining good ventilation.
(3) Magnetic Field
Please contact us in the case this instrument is
installed the strong Magnetic Field.

Isc ≤ 165mA
Pmax ≤ 0.9W
3. Installation
• Control equipment connected to barrier must
not use or generate more than 250 Vrms or
Vdc.
• The safety barrier must be CSA certified.
• Associated apparatus manufacturer’s
installation drawing must be followed when
installing this apparatus.
• The maximum power delivered from the barrier
must not exceed 0.9 W.
• Note a warning label worded “SUBSTITUTION
OF COMPONENTS MAY IMPAIR INTRINSIC
SAFETY” and “INSTALL IN ACCORDANCE
WITH DOC. NO. ICS006-A12 P.1 AND 2”.
1.5.2 TIIS Intrinsically Safe Type
The model PK200/JS3 current-to-pneumatic
converters, which have obtained certification
according to technical criteria for explosion-
protected construction of electric machinery and
equipment (Standards Notification No.556 from
the Japanese Ministry of Labor) conforming to IEC
standards, is designed for hazardous areas where
explosive gases and/or inflammable vapors may be
present. (This allows installation in Division 0, 1 and
2 areas)
