z Designed to t all Sun FLeX Series on/o and proportional valves (see Page 7).

z Global certications include ATEX, IECEx, CSA (see “Hazardous Certications” table on Page 3).

z All hazardous location coils are certied for gas and dust environments (T4 compliant for gas

and T135° C for dust).

z The coil is CE compliant.

z These coils are fully RoHS compliant. Restricted materials comprise less than 0.1% total weight.

z IP66 rating (with suitable certied cable entry or conduit per IEC 60529).

z 1/2” NPT or M20 x 1.5 female thread for electrical connections are available.

z Includes vibration-resistant push-to-connect terminal block. Power cable with mating connector

is required and not included with this product.

z The external steel shell is zinc-nickel plated (1000-hour salt fog protection).

z Fin-free design prevents build up of grease, dust and debris.

z The coil is magnetically symmetrical and can be mounted in either direction on the solenoid

tube without aecting performance.

z A transient voltage suppression (TVS) diode is built into the DC coils and oers a 48-Vdc

breakdown voltage. The AC coils are internally rectied.

z For optimum performance when used on a proportional valve, an amplier with current

feedback and adjustable dither should be used. Dither should be adjustable between 80-250 Hz.

SPECIFIC CONDITIONS FOR SAFE USE

The temperature of the uid owing through the valve and the solenoid must not exceed the ambient

temperature specied on the nameplate.

The temperature at the entry point may be as high as 130° C (266° F) for T4. This should be taken into account

when selecting suitable cable and entry devices.

Do not open the cover while solenoid is energized.

The special fasteners that are used in these devices are type M4 x 0.7 with a yield stress of 700 MPa; any

replacement fasteners must conform to these requirements.

North American application: Internal electrical connections must be factory installed.

Warning: Failure or improper selection or improper use of the products described herein or related items can

cause death, personal injury and property damage. Users, through their own analysis and testing, are solely

responsible for making the nal selection of the system and components and assuring that all performance,

endurance, maintenance, safety and warning requirements of the application are met.

INSTALLATION INSTRUCTIONS

1. Mount coil onto spool (tube) body.

2. A cable entry hole is provided to accommodate any suitable certied ameproof cable entry device.

Cable entry temperature may exceed 70° C (158° F).

3. Remove terminal box cover and connect electrical supply and earth to terminal block. Conductors ac-

cording to Note 4. Note coil is polarity insensitive. The center terminal is the internal ground. Replace

cover and secure with the four screws. Torque to min 1.92 ft-lbs (2.6 N-m).

4. Connect external ground. North American applications: external earth (ground) connections. Use

where local codes or authorities permit or require external earth (ground) connections. Torque to 1.25

ft-lbs (1.7 N-m).

5. When installing with multiple coils, the coils must spaced a minimum of 0.875” (22.23 mm) apart to

ensure adequate heat dissipation.

NOTE

Please verify cartridge clearance requirements when choosing a Sun manifold. Dierent valve controls and

coils require dierent clearances. An additional 2.00” (50,8 mm) beyond the valve extension is needed for

coil installation and removal.

RECOMMENDATION

For installation in above-ground electrical systems in explosive atmospheres, procedures for all applicable

codes must be observed. All work must be carried out by an electrician with adequate qualications for

hazardous locations.

A common practice to protect the internal bridge rectier from unknown incoming voltage conditions is to

install a TVS diode. For the 115-Vac coil, diode part number 1.5KE250CA is recommended; for the 230-Vac

coil, diode part number 1.5KE400CA is recommended. Depending on the application, diodes higher than

1500 W are recommended.

VALVE COMPATIBILITY

MODEL 747 HAZARDOUS LOCATION COILS

12/24VDC, 115/230VAC

Our 747 Series hazardous location coils are compatible with

the FLeX family of solenoid-operated directional, proportional

and relief valves and newly released non-FLeX solenoid-

operated valves.

For a complete list of compatible valves for each coil, please

refer to the coil model on our website:

VALVE COMPATIBILITY

XMD Single- and Dual-Output Drivers

The XMD is a single- or dual-output driver used with solenoid-operated electro-proportional valves for the mobile and industrial

hydraulic industries. The XMD drivers are compatible with the 747 Series hazardous location coils, but the drivers themselves are

not tested or certied for hazardous locations.
