Mounting the device
The WirelessHart adapter can be mounted in one of three ways:
•
direct connection to the field device,
•
separate from the field device, but connected by a cable,
•
when used as a repeater, as an autark unit.
Direct connection
The direct connection to a field device is made by means of an adapter piece which is
screwed into the cable entry at the side of the adapter (see chapter 3.2.1).
Separate mounting
The adapter can be mounted on a wall (see chapter 3.2.2), post (see chapter 3.2.3) or
other object, using the adapter wall/pipe mounting kit, which is available as an accessory.
The connection to the field device is made with standard installation cable and two cable
glands. It is recommended that the blind plug be left in place until the electrical connection
is made.
It is recommended that the WirelessHART adapter be installed separate from a field device
when:
•
there is insufficient space at the measuring point to mount the adapter on the field
device,
•
the signal reception at the measuring point is too weak for correct operation,
•
the measuring point is subject to vibration above the permissible limits (see
>>>>>>>>>> Technical Data).

Depending on the order, the following parts may be supplied:
•
adapter piece for connection to a field device with a M20 cable entry,
•
adapter piece for connection to a field device with a G 1/2 cable entry,
•

•
