5.5 Protective Conductor System
AFS devices must be grounded at the ground plate or ground bolt indicated in accordance with EN60204-1.
Before the AFS device is turned on, the protective conductor system of the entire system must be inspected
and safe operation ensured.
A ground bolt is mounted ex factory. Depending on the device type, multiple locations have been
provided for ground bolts at the base of the device or the carrier.
If necessary, the ground bolts can be mounted elsewhere. The ground bolt is to be connected to the
metal housing structure by a professional.
5.6 Startup Operations
Before the device is turned on, all electrical wires, pipes, ducts, and the AFS device must be examined for
proper installation and mechanical damage and leaks.
Before the device is turned on, all electrical wires, pipes, ducts, and the AFS device must be examined for
proper installation and for mechanical damage and leaks.
The following must be ensured:
§ All filter elements must be arranged properly; see Figure 10
§ All filter elements must be as delivered
§ The motor must be turning in the correct direction
§ The AFS device must be securely placed and bolted down at its location
§ There must be no debris (shavings, screws, installation materials, etc.) inside the device, the
pipes, or the ducts.
The suction output for AFS devices with frequency converters can be adjusted and readjusted
manually.
The operating principles of all AFS air purification devices are the same; they differ only in scale,
ventilation system performance, and number of filters used regardless of device type.
