Adjustable Disconnect Settings
The adjustable disconnect setting values vary depending on whether the inv erte r is
a 208 Vac/60 Hz, 240 Vac/60 Hz, or 230 Vac/50 Hz model. Utility permission is
required prior to changing the settings on the inverter.
The default values of these settings differ from the utility specifications on
page A–2. These differences take into account the accuracy ranges listed in the
table below, and are intended to ensure that utility specif ic ations are always met.

Output Power Versus Ambient Temperature

Once the heat sink on the inverter reaches a maxim u m temp e rat ure lim it, the GT
Inverter reduces its energy output to ensure maximum component ratings are not
exceeded.
