Power Supply / Power Wiring Specifications
1. Space II unit and indoor units must obtain power from separate breakers:
• Space II unit: 1Ø, 208-230V, 60Hz
• Indoor units: 1Ø, 208-230V, 60Hz (Indoor units draw minimal power. Where permitted by National Electrical Code and local codes, it may
be prudent to connect multiple indoor units to a properly sized breaker.)
2. Power supply wire type and size should be selected based on National Electrical Code and local codes. Maximum allowable voltage
fluctuation ±10% or nameplate rated value.
3. Properly ground the Space II unit and indoor units per National Electrical Code and local codes.

:Copper Wire
Terminate multiple power wires of
the same gauge to both sides.
Do not terminate two wires on
one side.
Do not terminate different gauge
wires to a terminal block.

Connecting the Power Wiring
Best practice dictates using ring or spade terminals to terminate power wiring at the power
terminal block.
If ring terminals or spade clips are not available, then:
• Do not terminate different gauge wires to the power terminal block. (Slack in the wiring may
generate heat.)
• When terminating wires of the same thickness, follow the instructions demonstrated in the
figures below.
If power wires are not properly terminated and rmly attached, there is risk of re, electric shock, and physical injury or death.

Figure 51: Proper and Improper Power Wiring Connections.
• Firmly attach the wire; secure in a way to
prevent external forces from being impart-
ed on the terminal block.
• Use an appropriately sized screwdriver for
tightening the terminals.
• Do not overtighten the connections; over-
tightening may damage the terminals.
