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

• Preliminary Information
• Mounting the Unit
• Layout
• Wiring Diagrams
• Key
• Product Symbols

2.1 Preliminary Information

• Precautions
• Safety Precautions
• What Comes in the Package

2.1.1 PRECAUTIONS

• Protection provided by the equipment can be impaired if the equipment is used in a manner not specified by the manufacturer!
• 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.
• Keep the Expansion Unit as far as possible from heavy contactor boxes and other sources of electrical interference.

2.1.2 SAFETY PRECAUTIONS
CAUTION These units must be installed by an authorized electrician. 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).

2.1.2.1 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.
• Every low power device (digital, analog, or communication) must have a shield cable connected to the unit ground strip.

2.1.2.2 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.
• 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.

2.1.3 WHAT COMES IN THE PACKAGE

• One expansion unit
• One hanging bracket
• Two screws

2.2 Mounting the Unit

• Knockouts
• Hanging the Unit

2.2.1 KNOCKOUTS

1. Using the supplied clips and screws, mount the TRIO Expansion.

2. On the bottom the unit are knockouts used to route the low and high voltage cables.
   o Using a screwdriver and a hammer, gently apply pressure to the knockouts.
   o Only open up the holes that you require.
   o Munters recommends removing the knockouts before mounting the unit.

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!

4. Close the Expansion Unit 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 Expansion Unit for a few hours and re- check for proper operation.

2.2.2 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).

2.3 Layout

2.4 Wiring Diagrams

• TRIO to TRIO Expansion Wiring
• High Voltage Relays
• Power

2.4.1 TRIO TO TRIO EXPANSION WIRING

• The cable between the controller and the expansion unit should be a 4 wire twisted shielded cable (22 or 24 AWG).
• 1: Red wire
• 2: Black wire

2.4.2 HIGH VOLTAGE RELAYS

NOTE The relays control motors and heating devices via contactors, not directly.

2.5 TRIO / TRIO Expansion Termination
When TRIO is wired to a TRIO Expansion unit, the termination dipswitch in both units must be set to ON.

When the TRIO is not wired to an Expansion device, the termination dipswitch must be set to OFF.
2.6 Key
Ensure that the unit remains locked to prevent unauthorized access to internal components.

2.7 Product Symbols
The following labels appear on your controller:
Caution! Hazardous voltage
Caution: Refer to the manual
Main Protective Earthing Terminal
CAUTION IF THE UNIT IS USED IN A MANNER NOT SPECIFIED BY THE MANUFACTURER, THE PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED.

Mapping Devices

Install and wire the Expansion unit to the TRIO and to the external devices before beginning.

After wiring devices to the TRIO Expansion Unit, each device must be mapped and then defined.
Mapping and defining devices enables the system software to control each device’s functionality.
CAUTION Mapping MUST match the physical wiring! An error message appears if the physical device is not wired to the relay or port as defined on the mapping screen..
To map the devices:

1. Go to System > Device and Sensors.
   

2. Click Expansion.
   

3. Map the devices as detailed in the TRIO manual. Refer to the manual for more information.
