5.2.3 Wiring for power supply via battery 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.
Mounted directly on the
field device 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 battery unit" section on Page 44.
4. Wire the field device as described in the operating manual 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.
Remote mounting For WirelessHART Adapters with a battery unit, we recommend you perform the wiring between
the WirelessHART Adapter and the field device via the secondary cable entry. The secondary cable
entry is located on the bottom of the WirelessHART Adapter.
Note!
• If the primary cable entry must be used, make sure that the water does not flow along the cable
and enter the housing.
