Electromagnetic compatibility (EMC):
The AirBox is rated for operation in industrial environments. The test
of the electrostatic discharge was carried out in accordance with
EN 61000-4-2 with the following test levels:
• Contact discharge ±4kV
• air discharge ±8kV
Special applications such as the conveying and distribution of bulk
material can generate higher electrostatic charges.
To avoid electrostatic discharge the following remedial actions are pos-
sible, among others:
• Equalisation of potential according to the installation instructions
• Separate laying of
- signal and bus cables
- equipotential bonding conductors
- power cables
• physical separation of the AirBox and all cables from all parts carry-
ing or discharging electrostatic charges
If these discharges are not avoided there is the danger of:
• injury to/incapacitation of operators and maintenance staff
• spark formation
• damage to the AirBox
• damage to the electrical equipment
The electrical triggering has priority over the mechanical
triggering.
