3.3.8 Verifying tightness of cable glands
• Adjustable wrench
To maintain enclosure tightness and provide strain relief to the cables, all cable glands must be
tightened. Unused cable glands must remain plugged.
1. Check every cable gland that is in use:
a. Pull on the cable to verify that the cable is securely held by the cable gland.
b. Tighten the cable gland if the cable moves.
2. Check that every unused cable gland is plugged and tightened.

Connecting probes
The IP classification of probes is valid only when the probes are
connected to the probe connection cable.
CAUTION!
If you want to configure the probe settings, such as purge interval, you must do
that before connecting the probe to the transmitter. To configure the probe, you
can use the free Vaisala Insight PC software. For more information, see your
probe's user guide and visit www.vaisala.com/insight.
If your transmitter was delivered with preconfigured analog outputs, make sure
that you connect the probes accordingly. See the label inside the transmitter
enclosure for the correct order of the probes.
