SkyBox
Here is an example of how to wire the Tigo TS4-R-S with a SkyBox unit. The key is to give the SkyBox
a closed circuit signal during normal operation and an open circuit during a rapid shutdown event.
Two different options are:
 Wiring across a dry contact that opens during a rapid shutdown event, and connecting that to the
SkyBox RSD input on the C
ONTROL WIRING TERMINAL BLOCK (also called the AUX terminals).
 Connect the 24 Vdc output of the switch to a 24-volt-rated normally open device that will open
upon loss of 24 Vdc and close with the presence of 24 Vdc.
A 3
rd
party NEC compliant switch should be used. The device OFF position shall indicate that the
rapid shutdown function has been initiated for all PV systems connected to that device. An LED or
other indication may need to be used depending on the switch.
