To measure ground connection:
NOTE!
The duct system (inlet and outlet) is NOT to be connected during
measuring.
1. Disconnect mains ground from GND1.
2. Measure between all components according to the list above and GND1.
The value is to be ≤100 ohm.
3. Measure and check whether there is contact between the incoming duct
system and the disconnected incoming mains ground. The value is to be
≤10
4. Connect the incoming duct system. Ensure that there is a second ground
connection between the duct system and the unit and that it is properly
grounded to the unit.
1)
5. Reconnect mains ground to GND1.
6. Connect the outgoing duct system. Ensure that there is ground connection
between the duct system and the unit.
8.4 Compressed air installation
WARNING!
Use ear protection and safety goggles!
Requirements
For air consumption, quality and max. and min. pressure, see
Section '5.3 Technical and electrical data'.
NOTE!
The specified air consumption of the unit is limited to the short
operation of the cleaning valve.
As new ducts may contain dirt, particles or debris, the compressed air pipe
is to be blown clean before connecting E-PAK 150 DX/300 DX/500 DX. A
compressed air filter, see Figure 9, item 9, is to be installed to ensure the
reliable and safe operation of the unit. A compressed air valve, that vents the
remaining pressure of the unit, is to be installed, see Figure 9, item 10.
NOTE!
Take measures necessary to avoid water or humidity in the
compressed air when the unit is installed in cold environments.
NOTE!
If antifreeze additives are used, use them continuously. Once added,
the removal of the antifreeze additive may cause the pneumatic components to
malfunction.
WARNING!
The compressed air valve is to be locked in the closed position during
maintenance.
Installation
Connect a compressed air supply to the inlet under the start and control unit,
see Figure 9.
NOTE!
Secure the compressed air line properly.
