WirelessHART Adapter SWA70 5 Electrical installation
Hauser 31
5.2.2 Wiring for power supply via electronically controlled power
supply unit
You can mount the WirelessHART Adapter either directly on the field device or at a distance from
the field device on a wall or post using a bracket. See the "Wall mounting" section on Page
22 and
see the "Pipe mounting" section on Page 23.
As the secondary cable entry is always used for the power supply on WirelessHART Adapters with
a wide range power unit, solar module connection or intrinsically safe power unit, the primary cable
entry must always be used for wiring between the WirelessHART Adapter and the field device.
Note!
• For the primary cable entry make sure that the water does not flow along the cable and enter the
housing.
Proceed as follows to mount directly on the field device:
1. Open the housing of the WirelessHART Adapter.
2. Guide the cable through the cable entry.
3. Wire the cable with the appropriate terminals of the WirelessHART Adapter.
– See the "Wiring diagrams for wide range power unit" section on Page 34.
– See the "Wiring diagrams for solar module connection" section on Page 38.
– See the "Wiring diagrams for intrinsically safe power unit" section on Page 41.
4. Wire the field device as described in the Operating Instructions for the field device in question.
5. If the field device is not put into operation immediately after wiring, close the housing of the
WirelessHART Adapter and the connection compartment of the field device. Tighten the
housing screws of the WirelessHART Adapter with a torque of 0.6 Nm.
