Dear Customer, The ES51 high voltage power supplies are power supply units for the series R5x AC discharging bars. The discharging bars and the ES51 power supply are used mainly in cases where disruptive static charges on fast-moving material webs impair production processes and need to be eliminated.

• Any work involving the units must be carried out by qualified electri- cians (see chapter 5 "Maintenance”, page chapter 6 "Trouble- shooting”, page 17). • Before starting the unit make sure that the appliance is permanently grounded via the grounding terminal (6, Fig. 1). The ground cable should have a minimum cross section of 1.5 mm (see chapter 3.2...
The manufacturer reserves the right to make changes to the technical specifications without prior notice in order to adapt the units to state-of- the-art engineering. Eltex will provide the latest information on any changes or modifications in the operating instructions on request.
3. Installation and assembly 3.1 Assembly the power supply The power supply is designed for wall mounting. Attach using the brackets provided (installation dimensions, see Fig. 2). The operating elements of the power supply and the terminals must be freely accessible at all times and the display LEDs must be visible.
3.3 Selecting the discharging bar Eltex discharging bars and ion blowers for AC operation can be connected to the ES51 power supplies. 3.4 Connecting the high voltage cable Warning! Connect or disconnect the high voltage cables only with the power supply...
3.5 Maximum active bar length and length of the high voltage cable Both the lengths of the high voltage cable and of the active bars are lim- ited. The shielded high voltage cables cause a capacitive load on the transformer inside the power supply. The maximum loading capacity is a result of the function of the total active bars length and the total length of all high voltage cables.
3.7 Connecting socket for function and fault signals The 5-pin connecting plug (Fig. 5) is only provided in units equipped with function and pollution monitoring. Depending on requirements, the follow- ing signals can be picked up at this plug: • Output voltage active: contact 1, 2, 5 (contact 1 and 5 closed) •...
4. Operation 4.1 Startup Before starting up the power supply the user must make sure that the power supply and the bars have been installed and assembled correctly. The supply voltage can then be switched on. Use the toggle switch (4, Fig. 1) to switch on the power supply. In the ON position the switch lights up green.
5. Maintenance Warning! Electric shock hazard! • Switch the power supply off and disconnect the supply voltage before carrying out any maintenance or repair work. • The machine in which the discharging bars are installed must not be in operation. •...
