Low Voltage Directive

TIIS Certification

A) TIIS Flameproof Type
The model FVP110 Valve Positioner with optional code /JF3, which has 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
inflammable gases or vapors may be present. (This allows installation in Division 1 and
2 areas)
To preserve the safety of flameproof equipment requires great care during mounting,
wiring, and piping. Safety requirements also place restrictions on maintenance and
repair activities. Users absolutely must read "Installation and Operating Precautions for
JIS Flameproof Equipment" at the end of this manual.
When selecting cables for TIIS flameproof type positioners, use cables having a
maximum allowable heat resistance of at least 70 °C.
Low Voltage Directive
Applicable standard: EN61010-1

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.

Installation Category I

Overvoltage category (Installation category) 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
(interfaces) are provided.
