Page 6: Safety
These power supplies guarantee the optimum adaptation to the required operational data for the different active bar lengths. Safe operation of the bars is ensured only by using the Eltex power supplies. Modifications or changes to the discharging bars are not permitted. -
Page 7: Work And Operational Safety
2.3 Work and operational safety Warning! Carefully observe the following notes and the complete chapter 2 "Safety”, page • Before carrying out repairs, cleaning or maintenance work and before resetting the unit after malfunctions, switch off the power supply and dis- connect the supply voltage (see chapter 5 "Maintenance”, page chapter 6 "Trouble-shooting”, page... - Page 8 • In bilateral discharging, the bars must not be mounted in opposition to each other. The distance between both bars should be greater than twice the bar distance from the web (see chapter 3.1 "Assembling the discharging bar”, page 10). •...

Page 9: Contact Protection
Shortening the shielded high voltage cable on the connecting side of the power supply is permitted. Extending the cable is permitted only when using the Eltex distributor as well as original high voltage cables and glands. • The operation of the bars can generate ozone. The ozone concentration levels developing near the bars depend on many different factors such as site of installation, bar current and voltage, air circulation, etc., and... -
Page 10: Installation And Assembly
3.1 Assembling the discharging bar Attach the Series EXR5C discharging bars to the machine wall, using flame-retardant GRP assembly material. For easier installation we recom- mend using the assembly material offered by Eltex. Fig. 2 shows the installation principle. Fig. 2:... - Page 11 Plastic holder below 1 meter total length: 3 per bar below 2 meters total length: 5 per bar below 3 meters total length: 7 per bar below 4 meters total length: 9 per bar below 5 meters total length: 11 per bar below 6 meters total length: 13 per bar Fig.
- Page 12 Warning ! For safety in operation, please note the following: • The bar must be mounted such that mechanical damage to the bar tips is ruled out. • To attach the bars, use only sliding nuts and bolts made of plastic. •...
- Page 13 Locating the discharging bar The best possible discharge results are achieved if the bar is located in areas with minimum web capacities. In practical terms this means placing the bar with maximum distances from the machine environment, i.e. no installation of the discharging bar at idler rollers. A rough guideline: A space with the radius R of the bar distance from the web ought to be kept free of any conductive material (Fig.

Page 14: Length Of The High Voltage Cable
3.2 Length of the high voltage cable Both the lengths of the high voltage cable and the active bars are limited. The shielded high voltage cables cause a capacitive load on the trans- former inside the power supply. The maximum loading capacity is a result of the function of the total active bar length and the total length of all high voltage cables. - Page 15 3.4 Connecting the high voltage cable to the power supplies and the distributor boxes The connection of the high voltage cable of the discharging bars to the power supplies is described in the operating instructions of the respective power supplies. Warning! Electric shock hazard! Work may be carried out only if:...

4.2 Function control Use the Eltex Volt Stick or a glow-lamp voltage tester to check the proper function of the emission tips. Quote Article No. 109136 when ordering the Volt Stick from Eltex. -
Page 17: Maintenance
5. Maintenance Warning! Electric shock hazard! • Do not carry out any maintenance or repair work without first switching off the power supply and disconnecting the supply voltage. • The bars passively absorb energy from the moving substrate web. The high voltage cable must be plugged in or grounded to the power supply. -
Page 18: Trouble-Shooting
6. Trouble-shooting Warning! Electric shock hazard! • Do not carry out any maintenance or repair work without first switching off the power supply and disconnecting the supply voltage. No voltage must apply at the discharging bars. • Repairs and maintenance work must be carried out by qualified electri- cians only. -
Page 19: Warranty
The warranty applies only if the operating and assembly instructions spe- cified by Eltex have been observed. The warranty period begins on the date of delivery. In the event of defects occurring during the warranty period, the units or defective components will be repaired at Eltex. -
