Discharging electrostatically charged
surfaces - Discharge systems (options)
Intended use of electrostatic discharge systems
Electrostatic discharge systems are used to discharge electrostatic charges that adhere to
surfaces of laboratory equipment, gloves and powders. These devices consist of discharge
electrodes and high-voltage power supply units.
To achieve an optimal discharge effect, the discharge electrode connected to a high-voltage
power supply unit must be brought as close as possible to the object to be discharged.
However, direct contact with the electrode tips should be avoided.
We restrict the use of the discharge systems to the following safety enclosures
 ST1 safety weighing enclosures
 IE instrument enclosure
 SB type SafetyBox/Glovebox
 LEV type safety enclosure
Occupational and operational safety when working with electrostatic discharge systems
There is an immediate danger to life in case of contact with live parts. In case
of damage to the insulation (visible damage to cables), switch off the power
supply immediately and have repair carried out by qualified personnel. Please
note the following points:
• As long as the mains plug is not disconnected, parts of the unit's electrical
equipment could be live. Disconnect the mains plug before carrying out
maintenance work on the equipment.
• Always pull the power cable out of the socket by the plug only.
• Check the electrical equipment of the unit regularly. Eliminate any damage
immediately. Replace defective cables and plugs immediately.
• Do not bridge any fuses or put them out of operation. When replacing
fuses, observe the correct trigger values.
• Keep moisture away from live parts. This can lead to a short circuit.
