3.3.7 Verifying tightness of cable glands
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.
3.4 Attaching probes
Attach only Vaisala Indigo compatible probes to the transmitter. CAUTION!
The IP classification of probes is valid only when the probes are
attached to the probe connection cable.
CAUTION!
If you want to configure the probe settings, such as purge interval, you must do
that before attaching 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 .
When the probe connection cables have been wired to the transmitter, you can attach and
detach probes both when the transmitter power is on and when it is off. If the power is on
while you attach or detach a probe, the transmitter shows a notification about the probe. If
you have configured the transmitter to use outputs, the transmitter also notifies you of the
state of the outputs.
