GTIB-30 Installation Manual-UL

4411-0011, Rev 2.0
WARNING:
If the system is not equipped with an optional integrated GFDI, then
this inverter must be used with an external GFDI device as required by the Article
690 of the National Electrical Code for the installation location.
The GTIB-30 has an integrated isolation transformer installed allowing for external
grounding of the PV negative.
It is the responsibility of the installer to ensure that all grounding arrangements
are NEC compliant before proceeding with the installation. PPS takes no
responsibility for damage or injuries resulting from non NEC compliant
grounding arrangements.
4.12 PV Ground Wiring
The terminal blocks used to ground PV negative are inside the GTIB-30 inverter (see
below). Removing this jumper will effectively disable the optional internal GFDI
protection circuit. If a floating PV array is installed an external GFDI needs to be
installed and this jumper should not be in place.
