Introduction to Indigo300 transmitter
This document is a quick guide for taking Vaisala Indigo300 Transmitter into use.
For the complete user instructions, see Indigo300 User Guide (M212849EN).

Figure 1 Indigo300 connections overview
Vaisala Indigo300 Transmitter is a host device for displaying measurement values from Vaisala
Indigo-compatible probes and/or transmitting them to automation systems through analog
signals.
Probes can be connected to the transmitter tool-free using the locking wheel. You can connect
a probe to the locking wheel directly or by using a cable. Instead of the locking wheel, it is also
possible to use a cable gland with a fixed cable.
The service port on the front can be opened with a 4-mm Allen key for enabling access to the
free Vaisala Insight PC software or Indigo80 handheld indicator.
With Insight and Indigo80, you can configure both the transmitter and the probe connected to
it, as well as calibrate and adjust the probe without having to detach it from the transmitter.

If you are using a 24 V AC power supply for the transmitter, make sure to use
separate cables for the AC power and the analog outputs to ensure that the EMC
requirements are fulfilled.
Wiring from the back
1. Before connecting wires or cables, make sure that the transmitter is powered o.
2. Open the transmitter cover, if not already open.
3. Remove the center of the rubber lead-through to fit your cable through the opening. Use,
for example, a small screwdriver to thrust the small round center piece o.
4. Lead the cable through the opening.
To preserve the IP rating of the transmitter, the back of the
transmitter must rest flat on the installation surface. Make sure that you
route the cable so that it does not push the back of the transmitter o the
installation surface.
CAUTION!
5. Connect the wiring to the applicable screw terminals.
6. Fit the cable under the strain relief clip next to the rubber lead-through, as applicable. You
can also use the clip with a cable tie.
7. Reattach the transmitter cover.
Tighten the screws hand-tight using the 4-mm Allen key (recommended tightening
torque 3.6 Nm).
8. If you wire only through the back, plug or seal the unused lead-throughs on the bottom.
Wiring through bottom lead-throughs
1. Before connecting wires or cables, make sure that the transmitter is powered o.
2. Open the transmitter cover, if not already open.
3. Open the cable gland and insert a suitable length of the cable inside the transmitter
through the gland.
4. Connect the wiring to the applicable screw terminals.
5. Tighten the cable gland. Avoid overtightening.
• Tightening torque for M20 gland: 8 Nm
• Tightening torque for M16 gland: 6 Nm
6. Reattach the transmitter cover.
Tighten the screws hand-tight using the 4-mm Allen key (recommended tightening
torque 3.6 Nm).
7. Plug or seal the unused lead-throughs.

ENGLISH

Finalizing installation
After mounting and wiring the transmitter, do these final steps to have your transmitter ready
for use.
1. Verify the tightness of the cable glands. Pull on the cable to verify that the cable is
securely held by the cable gland.
2. To ensure that the transmitter operates as intended, Vaisala recommends grounding the
transmitter. Connect the grounding terminal on the bottom of the transmitter to the
grounding element of the installation site with a grounding wire.
3. Switch on the power supply input.
4. Connect the probe to the transmitter.
5. If you want your transmitter to get error log time stamps and calibration reminders for the
connected probe, connect the transmitter to the Insight PC software or the Indigo80
handheld indicator for automatic date and time setup.
Date and time setup is needed for calibration reminders and error log time
stamping to work.
