Installation
Hardware Options
The seven versions of the GSLC come with different components already installed.
 GSLC, the “basic” or “empty” version, requires almost all components to be installed if they are needed.
Instructions for this product begin on page 19.
 GSLC175-120/240 and GSLC175-230 are the “inverter only” versions for Radian models GS8048, GS8048A,
and GS7048E. They have hardware for Radian inverter AC and DC connections. Battery monitoring or PV
capability must be installed as needed. Installation for these items begins with the DC shunts on page 23.
 GSLC175-PV-120/240 and GSLC175-PV-230 are the “fully-loaded” versions for Radian models GS8048,
GS8048A, and GS7048E. They have all options already present and need only to have external wiring and
devices added. Users with either of these versions can skip to the wiring section on page 29.
 GSLC175PV1-120/240 and GSLC175PV1-230 are the “fully-loaded” versions for Radian models GS4048A
and GS3548E. They have all options already present and need only to have external wiring and devices
added. Users with either of these versions can skip to the wiring section on page 29.
Additional AC and DC circuit breakers are available for installation on all models.
The following pages describe the installation of individual items, including the removal of the GSLC
covers. Page 19 lists the hardware requirements for these items.
 Instructions for Radian inverter mounting (along with other devices) begin on page 25.
 Instructions for installing the FLEXnet DC battery monitor begin on page 33.
 Instructions for installing the AC input-output bypass (IOB) assembly begin on page 42.
