5.1 Low-voltage Electrical Field Connections
Figure 5.1 on the facing page, shows an overview of the low-voltage wiring connections between the
Mini-Mate module and the condensing unit (on DX systems only), and the wiring and cabling between the
wall-mounted iCOM display for all system types. Detailed connection information is included in the
submittal drawings listed in Table 5.1 on the previous page.
Connect field-supplied, shielded, Class 1 wiring from the condensing unit to the indicated terminal-strip
locations.
For the wall-mounted iCOM-controller display:
• Connect a field-supplied, CAT5 Crossover Ethernet cable between P64 on the iCOM-control
board in the Mini-Mate module and ETH-1 on the wall-mount iCOM display.
• Locate the wire harness inside the wall-mount display, and connect field-supplied, Class 1
wiring between the harness and landing on the terminal-strip 13, 14, and 15 in the Mini-Mate
module to provide power for the display.
For the wall-mounted temperature/humidity sensor:
• Plug the factory-supplied, CANbus cable into P66 on the iCOM-control board in the Mini-Mate
module and into P66, Ethernet connection on the temperature/humidity sensor.
