The mains power connection may be connected to the power

y an authorized electrician. A readily accessible

disconnect device must be incorporated in the fixed wiring.

WARNING!

• Do not detach the power supply module from the
transmitter when the power is on.

Do not connect the mains power to power supply module when it is not

•
installed in the transmitter.

• Always connect the protective ground terminal.

Preparing mains power cable

• Insulated ring terminal (size M4)
Cable cutters, cable-stripping pliers, crimping tool

1. Strip approximately 110 mm (4 in) of the power cable's outer sheath to expose the wires.

2.

Cut the line and neutral wires to the length of approximately 80 mm (3 in). If you are
using a stranded wire, Vaisala recommends adding cable ferrules to the ends.

3. Leave the grounding wire 110 mm (4 in) long.

4. Crimp an insulated ring terminal (size M4) to the grounding wire.

Make sure that the grounding wire is longer than the line and
neutral wires. Under mechanical stress, the grounding wire must be the last to
disconnect from the protective ground terminal.

Installing POWER-1 module

1. Disconnect power from the transmitter and open the transmitter cover.

2. If necessary, install a cable gland or conduit fitting in the transmitter for the mains power
cable. Make sure the outer diameter of the cable is compatible with the cable gland or
conduit fitting used.
If the power supply module has already been installed at the factory and you are installing
just the mains power cable, continue from step 5.

3. Connect the wires from the power supply module's terminals marked with + and − to the
power terminals on the component board of the transmitter.

4. Fasten the power module to the bottom of the transmitter housing with 4 screws.
See the figure below for the orientation of the module.

5. Thread the mains power cable through the cable gland or conduit fitting.

6. Connect the mains power wires to the power supply module terminals marked with
N and L.

7. Attach the grounding wire to the grounding terminal using the grounding screw and the
ring terminal at the end of the wire.
In the power cable supplied by Vaisala, the grounding wire is yellow-green.

8. Route the cable along the side of the module and tighten the cable gland (if used).

9. Close the cover. Connect power and verify that the transmitter starts up properly.
