Electrical Connections to Skystream
Caution: Turn power OFF prior to making electrical connections. Use a locking disconnect switch
to disconnect power and LOCK it when making connections!
The following section provides directions for completing the main power connections to the Skystream.
Warning: XZERES Wind strongly recommends and many local electrical authorities require a lockable
disconnect switch (Figure 3) installed between the Main Service Panel and Skystream.
Turn the switch to “Off” and lock the switch to prevent turning on the power
before it is safe to do so.

The connections are most easily accomplished with Skystream on the ground as would be the case
when utilizing a tilt-up tower. If the installation does not incorporate a tilt-up tower, the connections may
still be made on the ground by utilizing a sufficient length of cable to connect Skystream to the nearest
junction point.
Refer to the accompanying photographs and perform the following steps:
• Position Skystream on its side to access the yaw wire terminals.
• Remove approximately 0.3 inch (7 mm) of insulation from each of the Skystream yaw wires.
• Remove approximately 2 inches (5 cm) of cable jacket from the cable to be run down the tower and
strip approximately 0.3 inch (7 mm) of insulation from the individual wires See Figure 4.
•
Note: The AC field wiring terminals can be used for connection of a maximum of a single 8 AWG
(10 mm
2
) wire on each terminal.
• Pass the cable through strain relief clamp so approximately 0.5 in (1.5 cm) of cable jacket protrudes
past the clamp. Tighten the strain relief clamp screws to secure the tower cable.
• Connect each of the tower wires to the terminal block as shown in the accompanying photo.
Tighten the terminal block screws to 18-19 in lb (2.0 N · m). See Figure 5 or 6, as appropriate.
• Install the terminal block – cover assembly on Skystream using the socket head screws provided.
Tighten screws to 20-22 in lb (2.3-2.5 N · m).
After making the yaw wire connections, temporarily turn on power and immediately attempt to rotate the
blade shaft; the shaft should initially be difficult to rotate but become noticeably easier after 5 minutes.
Disconnect the power and verify that Skystream has returned to its “braked” mode. In the “braked”
mode the blade shaft should once again be difficult to turn.
