General presentation
The PIC is the gateway to allow communication between a TRANE
equipment and a BMS (Building Management Systems) vendor through the
Modbus protocol over a RS232 or a RS-485 link.
The PIC handles Modbus RTU according to Reference Guide: Modicon
PI-MBUS-300 Rev. D
Modicon®is a trademark of Modicon, Inc.
Jbus®is a trademark of April.
Modbus/Jbus Considerations:
Jbus is an extension of Modbus. Jbus supports more functions than
Modbus.
• Functions supported by both Modbus and Jbus:
1, 2, 3, 4, 5, 6, 15 and 16
• Functions supported by Jbus but not supported by Modbus:
7, 8, 11, 12 and 13

Mounting and wiring
PIC mounting recommendations
To mount the PIC device:
• Select a location near the controlled equipment to reduce wiring costs
and EMC disturbance risks.
• Verify that the location conforms to the specifications below.
• Secure the controller to a 35 mm DIN rail (Use only 10/10 mm thickness
sheet) or directly mount the PIC using four M3 screws (not supplied).
1 = Screw holes
2 = DIN rail

PIC Power Supply recommendations
The PIC device is powered by 24 VAC/VDC +6V/-12V power supply. A 3-wire
quickconnect terminal (TB3) is provided for power supply connection to the
board.
To ensure the controller will operate properly, verify that the power supply
circuit is in compliance with the following circuit requirements:
To keep the PIC in accordance with the Separated Extra Low Voltage (SELV)
circuit, the transformer 'T' shall be in accordance with EN / IEC 61558-2-6.
Table 3 - Power supply recommendations
CAUTION! PIC power supply circuit MUST NOT be connected to the ground
as shown in the above illustration.The non-respect of this requirement will
damage the PIC.
CAUTION! If local electrical regulations do not allow the recommended
power supply wiring, contact your local Trane Sales Office for an adequate
solution to comply with local electrical regulations.
Note:This wiring is in accordance with IEC 60364-4-41 and national
standards which incorporate the same requirements.

Protection
The PIC device must receive power from a dedicated circuit which is
connected to a dedicated isolation screened transformer. The circuit
must be protected by a 0.5 A / 250V / Medium time lag circuit
breaker/fuse located next to it.
Recommended
wire
The AC/DC-power wiring requires three-wire cable.
The recommended wire is 1.5mm² (16 AWG) copper wire.
Standards
The AC/DC-power wiring complies with IEC or EN 60364-4-41 and
2006/95/EEC for electrical safety.
For compliance with 2006/108/EEC and 89/336/EEC European directive
for electromagnetic compatibility:
- EN 55022 level B
- EN 61000-3-2
- EN 61000-4-2
- EN 61000-4-4
Ground
Connection
The ground connection of the PIC (GND connector) MUST BE
connected to the building earth to prevent electromagnetic
compatibility risks.
