Introduction The Meech Model 976EX has been designed to provide highly effective long range ionisation using Pulsed DC Technology. The 976EX Bar provides ionisation through alternating positive and negative emitter pins mounted in a profiled extrusion. The emitter pins are resistively coupled to the high voltage pulsed DC source, rendering the emitters shockless to touch.
II 2 GD EEx m Your Model 976EX Bar was carefully packed at the factory in a container designed to 1180 Gas group IIB, temp Class T6 (T85 1180 Gas group protect it from accidental damage. Nevertheless, we recommend careful examination T amb -20 to +35 C.
Installation The Model 976EX Bar should be located in the most convenient position so that the pins of the Bar are directed towards the target area. The bar should be positioned to give an unrestricted path for the ions to travel to the target area. It should typically be between 300mm and 600mm away from the target area.

UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NON-HAZARDOUS. Connect the mains supply to the Pulsed DC Controller and switch ON. The 976EX Bar will now produce Pulsed DC ionisation from the emitters of the Bar.

If the bar is positioned a long distance from the target area ( 600mm-750mm) the Rate should be set to the lowest setting. If the bar is positioned close to the target area (150mm -300mm) the rate should be set towards its maximum. If the polarity of the static charge to be removed is known the Balance can be adjusted to give a faster decay speed.
Special Conditions for Safe Use The 976EX eliminator bar shall be used in conjunction with either Meech Type 977v3 or Type 977HL power supplies. The power supply must be protected by a fuse capable of withstanding a prospective short circuit current of 4000A The bar shall be installed according to the manufacturer’s installation instructions...
Maintenance Cleaning your Meech Ioniser Ionisers require periodic cleaning. During normal operation, dirt will build-up on the emitter pins and upon the body of the ioniser. This will cause a reduction in performance. Typically, weekly cleaning is sufficient. However, equipment used in some heavy contamination areas, such as gravure printing or where plastic fumes are present, may require daily cleaning.

Emitter pins can be cleaned very effectively with a brush. A dry toothbrush is ideal. Ionisers will need periodic wiping to clean grey deposits from the surface of the bar. A cloth moistened with a small amount of IPA or methylated spirits is recommended.
Must only be carried out when the product is in a safe ( non-hazardous) area. Tests must be completed by a qualified electrical engineer. If in doubt contact Meech head office or your local distributor. CAUTION: Whilst no danger to personnel exists, it is essential that any high voltage ionising equipment, (exception Meech Model 910 Water Resistant Ionising Bars), makes no contact with water or water based fluids.

950 ) measure the voltage on each of the output sockets. The reading should be at minimum power 4kV and at maximum power 8 kV 13. Having checked the power supply, reconnect one Model 976EX Bar. 14. Using a high voltage probe (RS 610 281) and meter (RS 610 590) measure the voltage on the pins of the bar.
Repairs And Warranty The Meech 976EX Bar is warranted by Meech Static Eliminators Ltd. to the original purchaser against defects in material and workmanship for one year after purchase. Should any malfunction occur, please return the bar directly to Meech Static Eliminators or your local Meech Distributor.
