Step 2 — Main Power Connection 115VAC 1P
60Hz
1.
Locate the field supplied 14 AWG 3 conductor (L, N, G) power
cable.
2.
Set the main breaker to the OFF position, and ensure there is
no power being supplied through the power cable.
3.
Feed the power cable through the pre-drilled hole for high
voltage wiring shown in Fig. 2 and secure the line, neutral,
and ground leads to their respective terminals.
4.
Secure the power cable to the cabinet per local code.
NOTE: The three terminals labeled "LINE" are
jumped together. The three terminals labeled "NEU"

Step 3 — Toshiba Carrier VRF System
Configuration
1.
Use the field supplied communication cables to connect the U1,
U2 terminals on the TCC interface board to the U3, U4
communication terminals on the header condensing unit of the
Toshiba Carrier VRF system.
2.
Feed the communication cables through the pre-drilled hole
for low voltage wiring.
3. Secure the U1U2 communication cable to the cabinet per the
local code.
Fig. 3 —i-Vu Enclosure
1.
Use the following wiring materials to connect the field
supplied communication cable.
Line specification:
A. Type 2-core shielded wires
B. Wire size 16 gage, 330 ft. max.
C.
14 gage, 6500 ft max. Length (total length including air
conditioner systems area line length).
2.
Central Control address must be set in all indoor units to
establish communication with the Toshiba Carrier VRF system.
Step 4 — Connecting the i-Vu Open Link to
the i-Vu Server
1.
Locate the field supplied Ethernet cable for the i-Vu server.
2. Feed the Ethernet cable through the pre-drilled hole for low
voltage wiring along with the U1, U2 communication cables.
3. Secure the U1, U2 cable and Ethernet cable to the cabinet per
local code.
4. Ensure all dip switches on the open Link Router are set to
default.
