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.
