Wiring

and : Connect ground wires for battery, AC, PV, and additional PV equipment.

: Connect to SkyBox negative (–) , then connect to battery negative (–).

and : Connect PV array negative (–) and positive (+) wires.

Use terminals and

for a second array, if present.

: Connect all AC neutral wires.

: Connect SkyBox ground wire to in BOS.

: Ensu

re the rapid shutdown jumper or device is installed into A

UX terminals. Remove the

factory jumper before installing an external device. Route the wires through channel .

: Connect AFCI cable assembly to SkyBox socket .

and : Connect to the matching sockets in the wiring compartment.

: Connect SkyBox PV negative (–) wire to . Do not remove the jumper cap.

NOTE: is placed on the opposite side of the switch from and .

: Connect SkyBox PV positive (+) wire to . Ensure that all four screws at this location are tight.

: Connect to battery positive (+).

: Connect to SkyBox positive (+) .

and : Connect to load subpanel L1 and L2 respectively.

and : Connect to utility grid L1 and L2 respectively.

and : Connect to generator L1 and L2 respectively.

: If current transducers (CTs) are in use, they are installed at the main AC panel.

Route the L1 and L2 wires through channel and install into A

UX terminals.

(White wires use terminals 10 and 11; black wires use terminals 2 and 3.)

NOTE: A CT is labeled as oriented toward the “source”. “Source” is defined as

the SkyBox, NOT the utility grid. (A separate labeled arrow shows the location

of the utility grid.) Orient each CT accordingly for correct current readings.

: Connect internet or router cable to W

ALL port . Route through channel .

NOTE: Do not connect this cable to the other ports on the display.

: For batteries with a separate battery management system (BMS):

The BMS (CAN bus) adapter cable converts the RJ45 cable end to RJ11.

It connects to the BAT MON port . Do not insert the RTS or any other

RJ11 cable into the BAT MON port.

: If a BMS is not present: Connect the remote temperature sensor

(RTS). Attach it on a battery sidewall near the center of the bank.

: Connect generator start wires into A

UX terminals . (See the

key to the right.) Route through channel .

: To connect multiple SkyBoxes in parallel, connect the master to

the W

ALL on the next (slave) unit. The last SkyBox in

sequence has nothing in port . This marks it as the end unit.

(See the Commissioning section of this sheet and the NETWORK

tab in the SkyBox Programming Guide for additional steps.)

NOTES

 Make connections in the order indicated. If steps or connections are not applicable, they can be skipped.

 Tighten the applicable connections to the torque values specified in Table 1. (See opposite sheet.)

 Do not connect the PV positive (+) or negative (–) conductors to ground.

 Perform all wiring in accordance with Article 690 of the National Electric Code.

Current transducer connections on L1 and L2 AC inputs.

NOTE: Only L1 is shown in the wiring image, but both

must be connected. 10 and 11 are for hot wires; 2 and

3 are ground. See the SkyBox Programming Guide.

Rapid shutdown inputs (4 and 12).

These terminals connect to normally-

closed dry contact terminals on the

RSI (Rapid Shutdown Initiator). Use

OutBack’s ICS Plus or an equivalent

RSI system. See the RSI literature

and the SkyBox Overview Guide

(Troubleshooting section) for

instructions if rapid shutdown occurs.

Rapid shutdown outputs

(5 and 13). These are used to

duplicate the RSD connection

and function for an additional

SkyBox. They should be wired

to terminals 4 and 12 on the

next SkyBox.

Auxiliary (AUX) dry contacts (7 and 15) or 12-volt

contacts (8 and 16, up to 0.6 Adc) can serve as a

switch for Advanced Generator Start. (See the

SkyBox Programming Guide.)

NOTES:

 To install a wire, simply push it firmly

into the appropriate hole.

 To remove a wire, push on the release

next to it (the orange area) with a tool.

 Wire may be installed more easily by

pushing on the release with a tool while

inserting the wire.

 The entire terminal block can be unplugged

from the SkyBox to make this task easier.

Hole Release

IMPORTANT

 The SkyBox will not function unless the jumper or device is installed on the Aux terminals . It will show

a Rapid Shutdown fault.

 The SkyBox will not function unless the AFCI cable is connected. This must be done even if the surrounding PV

connections are not used. The screen will indicate an arc fault if not installed.

NOTE: Ensure the neutral and ground

conductors are mechanically bonded

at one point in the installation. DO NOT

establish more than one bond.
