INSTALLATION AND MAINTENANCE INSTRUCTIONS
Intrinsically safe/low power solenoid operator (ISSC – MXX)
GENERAL
This installation and maintenance instruction
sheet of the solenoid is a general supplement
to the particular I&M sheet for the valve. The
identication is made by prex IS to the cata-
logue number. Always use both I&M sheets for
installing and maintaining the solenoid valve.
DESCRIPTION
The solenoid valves are designed in ac-
cordance with Annex II of the European
Directive 2014/34/EU and IECEx Scheme:
IECEx 02. EC type examination certificate
KEMA 98ATEX2544X and IECEx certicate
IECEx KEM08.0017X are in compliance with
International and European standards:
ATEX
EN ISO 80079-36
EN ISO 80079-37
EN 60079-0 : 2012+A11 : 2013
EN 60079-11 : 2012
IECEx
IEC 60079-0 : 2011
IEC 60079-11 : 2011
IEC 60529 : 2001
Classication:
II 2G Ex ia IIC Gb / II 2D Ex ib IIIC Db IP65
INSTALLATION
ASCO™ components are intended to be used
only within the technical characteristics as
specied on the nameplate. Changes to the
equipment are only allowed after consulting
the manufacturer or its representative. These
solenoid valves are intended for installation in
potentially explosive atmospheres, Groups II A,
II B or II C gases, vapors, mists or dusts (Group
G/D, category 2). The surface temperature
classication is T6/85°C.
ELECTRICAL INSTALLATION
Wiring must comply with local and national
regulations of explosion proof equipment. Ap-
plication of the IS solenoid in the hazardous
area is not permitted without the addition of
an approved and classied device (such as
barriers), located between the safe and the
hazardous area. The purpose of the safety
device is to protect the equipment located within
the hazardous area from current and voltage
surges, which might enter the system from
the energy sources located in the safe area.
In addition the wiring to the equipment installed
within the hazardous location should satisfy par-
ticular requirements with respect to resistance
(R), inductance (L), capacitance (C), inductance
to resistance ratio (L/R) and screening. Due to
redundant blocking diodes the eective internal
inductance and capacitance of the solenoid are
neglibly small. To make the electrical connec-
tion to the spade plug connector, strip the outer
insulation of the cable back over approximately
30 mm and the insulation from the leads over 5
mm. Select the proper sealing ring Ø 6-8 mm
or Ø 8-10 mm depending on cable diameter.
Insert cable through the compression screw,
washer, sealing ring and connector housing
and connect wires to the terminal block. Place
terminal block into connector housing and as-
semble connector cover. Note that the cover
must be pressed properly to the connector
until a ‘click’ is heard. The terminal block can
be mounted in four dierent positions to select
the most favourable position for the cable entry.
Assemble the sealing ring, washer and tighten
the compression screw into the connector hous-
ing in such a manner that the seal ts tightly
around the cable. Position connector gasket,
place connector over coil spades and tighten
the central screw to specied torque to ensure
proper gaskets compression. The coil itself can
be rotated 360° to select the most favourable
position for the cable entry.

=
This current must always be greater than or
equal to 28mA for proper operation fo the
solenoid valve.
CAUTION
Electrical load must be within the range stated
on the nameplate. Failure to stay within the
electrical range of the coil rating results in
damage to or premature failure of the coil. It
will also invalidate the approval. If the solenoid
is used in a gas and/or dust environment, the
risk of electrostatic discharge shall be avoided.
SERVICE
To prevent the possibility of personal or prop-
erty damage, do not touch the solenoid. It can
become hot under normal operation conditions.
If the solenoid valve is easily accessible, the
installer must provide protection preventing
accidental contact. To prevent electrostatic
hazard, clean coil surface only with a damp
cloth. Do not use solvents.
MAINTENANCE
Maintenance depends on service conditions.
Periodic cleaning is recommended, the timing
of which will depend on the media and service
conditions. During servicing, components
should be examined for excessive wear. A com-
plete set of internal parts is available as a spare
parts kit. If a problem occurs during installation/
maintenance or in case of doubt please contact
Emerson or authorize representatives.
CAUTION: Before servicing the solenoid valve,
turn o electrical power, depressurize valve and
vent uid to a safe area.
Solenoid must be fully reassembled as the
housing and internal parts complete the mag-
netic circuit. In case of any replacement of parts
by the user, the traceability of the nal product
can not be guaranteed by Emerson. Wrong
assembly will invalidate the approval.
