Installation
Direct wiring (adapter mounted on field device)
When the adapter is mounted directly on the field device, the wiring is done through the
connection adapter as follows.
1. Open the housing of the adapter by unscrewing the four captive screws. Also open the con-
nection compartment of the field device.
2. Thread the two wires supplied through the connection adapter (primary cable entry).
3. Connect the WirelessHART adapter according to the appropriate wiring diagram.
4. If an external power line is to be connected, use the secondary cable entry.
5. Connect the field device according to the instructions in its operating manual.
6. If the devices are not to be commissioned immediately after connection, close the housing
and field device connection compartment.
7. In order to obtain optimal sealing of the adapter housing, tightened the screws to a torque of
0.5 Nm.
Wiring (adapter mounted separately)
1. Open the housing of the adapter by unscrewing the four captive screws. Also open the con-
nection compartment of the field device.
2. Using a M20x1.5 cable gland, thread the connecting or power cable through the secondary
cable entry into the adapter.
3. Connect the WirelessHART adapter according to the appropriate wiring diagram.
4. Pull the cable taut. The adapter cover is a tight fit an a trapped cable may prevent proper
closure.
5. Tighten the cable gland.
6. Connect the field device according to the instructions in its operating manual.
7. If the devices are not to be commissioned immediately after connection, close the housing
and field device connection compartment.
8. In order to obtain optimal sealing of the adapter housing, tightened the screws to a torque of
0.5 Nm.
9. Tighten the cable gland and, if required, the blind plug to a torque of 3.5 Nm.
