Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants.

Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

WARNING
Proper Field Wiring and Grounding Required! Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.

Communication Link Wiring

The Symbio™ 500 controller communicates with the building automation system (BAS) and with other controller over a BACnet® MS/TP, BACnet/IP, or Air-Fi Wireless communication link.

Important : BACnet MS/TP link wiring must be field-supplied and installed incompliance with NEC and local codes. For instructions on BACnet MS/TP communication wiring, refer to the Unit Controller Wiring For the Tracer® SC+ System Controller Wiring Guide (BAS-SVN03*-EN).

A/C Power Wiring
Prior to connecting AC power to the controller:

• All wiring must comply with National Electrical Code™ (NEC) and local codes.
• The recommended wire for AC power is 16 AWG copper wire, minimum.
• Refer to “Transformer Recommendations

NOTICE Enclosure Damage!
Failure to follow instructions below could result in damage to the plastic enclosure. Do not use excessive force to install the controller on the DIN rail. If using another manufacturer’s DIN rail, follow their recommended installation.

WARNING Hazardous Voltage!
Failure to disconnect power before servicing could result in death or serious injury. Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Verify that no power is present with a voltmeter.

WARNING Proper Ground Connection Required!
Failure to follow instructions below could result in death or serious injury. After installation, ensure that the 24 Vac transformer is grounded through the controller. Measure the voltage between chassis ground and any ground terminal on the controller. Expected result: Vac <4.0 volt.

18 AWG copper wire is recommended for the circuit between the transformer and the Symbio 500.

Transformer Recommendations
The Symbio™ 500 can be powered with 24 Vac. Use of a 24 Vac power supply is recommended in order to use the spare 24 Vac outputs for powering relays and TRIACs.

• AC transformer requirements : UL listed, Class 2 power transformer, 24 Vac ±15%, device max load 24 VA, BCI application 6 VA. The transformer must be sized to provide adequate power to the Symbio 500 controller (12 VA) and outputs (maximum 12 VA per binary output).
• CE-compliant installations : The transformer must be CE marked and SELV compliant per IEC standards.

Equipment Damage!
Sharing 24 Vac power between controllers could result in equipment damage

A separate transformer is recommended for each Symbio 500. The line input to the transformer must be equipped with a circuit breaker sized to handle the maximum transformer line current. If a single transformer is shared by multiple Symbio 500s:

• The transformer must have sufficient capacity.
• Polarity must be maintained for every Symbio 500 powered by the transformer.

Important : If a technician inadvertently reverses polarity between controllers powered by the same transformer, a difference of 24 Vac will occur between the grounds of each controller. The following symptoms could result:

• Partial or full loss of communication on the entire BACnet® MS/TP link.
• Improper function of Symbio 500 outputs.
• Damage to the transformer or a blown transformer fuse.

Wiring AC Power

1. Connect both secondary wires from the 24 Vac transformer to the XFMR terminals on the device.
2. Ensure the device is properly grounded.

Important : This device must be grounded for proper operation! The factorysupplied ground wire must be connected from any chassis ground connection on the device to an appropriate earth ground The chassis ground connection used may be the 24 Vac transformer input at the device, or any other chassis ground connection on the device.

Note : The device is not grounded through the DIN rail connection

Start-up and Power Check

1. Verify that the 24 Vac connector and the chassis ground are properly wired.
2. Each device must have a unique and valid address. The address is set either by using the rotary address switches or, for Tracer® SC applications, by using the Software Set Device ID function in the Tracer® TU service tool. Valid addresses are 001 through 127 for Tracer® SC applications. Important: A duplicate address or a 000 address will cause communication problems in a BACnet® link: The Tracer® SC will not discover all devices on the link and the installation process will fail after discovery.
3. Remove the lockout/tagout from the line voltage power to the electrical cabinet.
4. Apply power to the Symbio 500 and observe the power check sequence that follows: The power LED lights red for 1 second. Then it changes to green, indicating that the unit is properly booted and ready for application code. Flashing red indicates that a fault conditions exists.

Input/Output Wiring

Equipment Damage!
Failure to follow instructions below could result in damage to the controller, power transformer, or input/output devices due to inadvertent connections to power circuits. Remove power to the Symbio™ 500 controller before making input/output connections. Pre-power checks of input/output devices should be performed according to the Symbio 500 IOM (BAS-SVX090*-EN). Maximum wire lengths are as follows:\
