power cable
1 Line wire
2 Grounding wire
3 Neutral wire
1. Strip 55 mm (2.17 in) of the cable to expose the wires.
2. Cut o 10 mm (0.39 in) of the line and neutral wires. Leave the grounding wire 55 mm
(2.17 in) long.
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.
CAUTION!
3. Strip the ends of the individual wires to expose the conductors for a length of 8 mm
(0.32 in).
Relay output terminals and lead-through
Before connecting wires or cables, make sure that the transmitter is powered o.

Relays are not available in transmitters that
are powered with Power over Ethernet.
Wire the relay connections as normally
open (NO) or normally closed (NC). Use
the touchscreen or web interface to
configure the relay activation parameters.
For the M20×1.5 cable gland ordered
together with the transmitter from Vaisala,
the cable diameter is 5.0 … 8.0 mm
(0.20 … 0.31 in). Tightening torque for the
cable gland is 8 Nm.
