4 Basic Safety Instructions
Order number 2317574 | Edition 10/2022 13
4For sufficient health and environmental protection, only operate the device with
technical ventilation (extraction) switched on.
4.2.2 Safe Handling of WAGNER Powder Spray Devices
Danger due to dust formation!
4Do not point spray guns at people.
4Do not spray device parts using electrostatic equipment.
4Before any work on the device, in the event of work interruptions and malfunctions:
4Switch off the energy/compressed air supply.
4Relieve pressure on spray gun and device.
4Secure the spray gun against actuation.
4Disconnect the control unit from the mains.
4In the event of functional faults, remedy the fault as described in the chapter on
troubleshooting.
4Carry out the work steps in accordance with the chapter on pressure relief in the
operating manual of the corresponding device:
4If a prompt for pressure relief is given.
4If coating work is interrupted or stopped.
4Before the device is externally cleaned, checked or serviced.
4Before the spray nozzle is installed or cleaned.
4.2.3 Grounding the Device
Danger due to electrostatic charge!
Explosion hazard and damage to the device.
The electrostatic charge may, in certain cases, give rise to electrostatic charges on the device.
Flames or sparks can form during discharge.
Correct grounding of the entire coating system prevents electrostatic charges:
4Ensure that all devices and tanks are grounded before each coating process.
4All conductive components of the system, such as floors, walls, ceilings, barriers,
transport equipment, work pieces, powder tanks, moving devices or structural parts in
the spray area, with the exception of parts under high voltage during operation, must
be connected to the grounding system.
Parts of the spray booth must be grounded.
4Ensure that all persons inside the working area are grounded, e.g., that they are
wearing static dissipative shoes.
4Grounding cables must be checked regularly to ensure that they are serviceable (see EN
60204).
4.2.4 Product Hoses
Danger due to damaged product hoses!
The product hose may cause dangerous injuries.
4Use only an original WAGNER powder hose.

4Preference should be given to non-ignitable cleaning fluids.
4Ignitable cleaning liquids may only be used if all high-voltage parts are discharged to a
discharge energy of less than 0.24mJ after shutting off the high voltage before these
parts can be reached. Most ignitable solvents have an ignition power in the range of
0.24mJ, corresponding to 60nC.
4The flash point of the cleaning agents must be at least 15K over the ambient
temperature.
4Note the details provided by the powder lacquer manufacturer.
4To correct for dust deposits, only mobile industrial vacuums of type1 may be used (see
EN60335-2).
4Take measures for workplace safety (see Chapter "A Safe Work Environment").
4.2.7 Maintenance and Repair

5.1 APPLICATIONS
The EPG S2 control unit is used to supply air and voltage to two WAGNER manual or
automatic powder spray guns, in Corona or Tribo versions. The control unit has no operating
elements; various operating statuses are simply displayed.
The module is operated with a superordinate controller (e.g. PLC) from which it receives the
necessary information.
The interface between the EPG S2 and master controller takes place by means of the
CANopen.
