1Introduction
1.1 Disclaimer
Munters reserves the right to make alterations to specifications, quantities, dimensions etc. for production
or other reasons, subsequent to publication. The information contained herein has been prepared by
qualified experts within Munters. While we believe the information is accurate and complete, we make no
warranty or representation for any particular purposes. The information is offered in good faith and with
the understanding that any use of the units or accessories in breach of the directions and warnings in this
document is at the sole discretion and risk of the user.
1.2 Introduction
Congratulations on your excellent choice of purchasing a Trio Swine Controller!
In order to realize the full benefit from this product it is important that it is installed, commissioned and
operated correctly. Before installation or using the controller, this manual should be studied carefully. It is
also recommended that it is kept safely for future reference. The manual is intended as a reference for
installation, commissioning and day-to-day operation of the Munters Controllers.
1.3 Notes
Date of release: Jan 2020
Munters cannot guarantee to inform users about the changes or to distribute new manuals to them.
All rights reserved. No part of this manual may be reproduced in any manner whatsoever without the
expressed written permission of Munters. The contents of this manual are subject to change without notice.

2Precautions
CAUTION
Protection provided by the equipment can be impaired if the equipment is used in a
manner not specified by the manufacturer!
CAUTION
There is a risk of explosion if the lithium battery is replaced with an incorrect type. Replace
the battery using the same type and manufacturer only.
•Grounding
•Filtering
•Checking the Battery Level
•Frequency Inverters
2.1 Grounding
•Always connect temperature and sensor shields to earth ground. Avoid mixing high voltage
wiring with sensor and low voltage wiring.
•Keep the controller as far as possible from heavy contactor boxes and other sources of
electrical interference.
•Do not connect communication wire shields, which go from one house to another at both ends.
Connect them at one end only. Connection at both ends can cause ground loop currents to
flow, which reduce reliability.
•The COM connection for communications is not the shield wire. The COM, RX and TX wires
must connect to each other at all controllers.
2.2 Filtering
If this installation includes a power inverter to drive variable speed fans, install an EMI filter in front of the
inverter, according to the specifications provided by the inverter manufacturer. Refer to the inverter
documentation.
2.3 Checking the Battery Level
Check the battery once a year. The output must be 2.7 volts (minimum). Authorized personnel only must
replace the battery if the output is below the minimum required level or every five years.
2.4 Frequency Inverters
Frequency inverters can cause severe electrical and electromagnetic interference. Therefore, when
employing a frequency inverter, it is critical that you carefully follow the manufacturer's installation
instructions.
In particular verify:
•That the cable shielding between the inverter and any motor meets industry standards
•Proper grounding of the inverter's chassis and motor power cable

© Munters AB, 2020 12
•Proper grounding of low voltage cable shield wire
•That the controller and inverter cables are kept in separate conduits or wire bundles
1. Controller
2. Inverter
3. Place the controller at least five meters from the inverter

3Unit Installation
The following sections detail how to mount and wire the Trio.
NOTE Munters recommends that a trained technician perform the following operations.

•Product Symbols
3.1 Preliminary Information
•Safety Precautions
•What Comes in the Package
3.1.1 SAFETY PRECAUTIONS
CAUTION
An authorized electrician must install these units. Disconnect the power to avoid electrical
shock and damage.
NOTE Installation Category (Over voltage Category) II
•The power supply to the controller should be protected by 1 amps circuit breaker.
•All electrical connections should comply with National Electrical code (NEC).
3.1.1.1 Grounding and Shielded Wiring
•
From the ground terminal, run a heavy wire directly to the ground rod. If necessary, run
a heavy ground wire to the electrical service grounding system rather than directly to the
ground rod.
•Do not use light wires for these ground connections. They must carry heavy lightning currents,
sometimes exceeding thousands of amperes. Certainly, do not use the shielding of sensor and
low voltage wiring for this purpose.
•When splicing sensors to longer wires, ensure that the splice is waterproof. Use adhesive lined
heat shrink (marine grade) to make waterproof connections.
•Every low power device (digital, analog, or communication) must have a shield cable
connected to the unit ground strip.
3.1.1.2 Installation and Electrical Connections
•Install computerized electronic controls at least three feet (one meter) away from interference
sources such as high voltage wiring to motors, variable speed, light dimmers, relays.

© Munters AB, 2020 14
•Install electronic controls in a separate ventilated control room that is protected from extreme
temperatures and dirty environments. Place the controls so that the operators can conveniently
use the control and read indicators and displays.
•Keep low voltage wires separate from high voltage wires.
•Use shielded wiring for low level signals. For buried wiring (building to building runs) use high
grade jell filled cables that are impervious to moisture.
•Seal cable entry points and control boxes to prevent contamination and corrosion. If you use
silicon sealant with acetic acid cure, keep the control open and ventilated until cured.
Otherwise, the acetic acid will attack the metal parts, including circuitry.
3.1.2 WHAT COMES IN THE PACKAGE
•One Trio unit
•One hanging bracket
•Two screws
3.2 Mounting the Unit
•Knockouts
•Hanging the Unit
3.2.1 KNOCKOUTS
1. Using the supplied clips and screws, mount the Trio.
2. On the bottom the Trio are knockouts used to route the low and high voltage cables.
Figure 1: Trio Knockouts and PG Size
oUsing a screwdriver and a hammer, gently apply pressure to the knockouts.
oOnly open the holes that you require.
oMunters recommends removing the knockouts before mounting the unit.
o16*: Use this knockout for the Ethernet cable.
3. Place the required cables through the cable holders at the bottom of the unit.
CAUTION Run low voltage cables through one knockout and high voltage relay cables through a
separate knockout. Do not place them in the same knockout!

© Munters AB, 2020 15
4. Close the Trio enclosure lid carefully and tightly. Use RTV silicon or equivalent sealant to seal the
cable holders.
CAUTION Munters strongly recommends that you seal all entry spots with RTV silicon. Failure to do so
can lead to damage to the unit.
5. After installation is completed, operate the Trio for a few hours and re- check for proper
operation.
3.2.2 HANGING THE UNIT
1. Attach the bracket to the wall (customer supplies the screws).
2. Hang the Trio on the bracket.
3. Secure the unit to the wall using the two screws provided (optional).
