Installing
the Inverter
2.2 Enabling the RTC (Real-Time Clock) Battery
The H100 series inverter comes from the factory with a CR2032 lithium-manganese battery pre-
installed on the I/O PCB. The battery powers the inverter’s built-in RTC. The battery is installed
with a protective insulation strip to prevent battery discharge; remove this protective film before
installing and using the inverter.
ESD (Electrostatic discharge) from the human body may damage sensitive electronic components on
the PCB. Therefore, be extremely careful not to touch the PCB or the components on the PCB with bare
hands while you work on the I/O PCB.
To prevent damage to the PCB from ESD, touch a metal object with your hands to discharge any
electricity before working on the PCB, or wear an anti-static wrist strap and ground it on a metal object.
Follow the instructions below to remove the protective insulation strip and enable the RTC feature
on the H100 series inverters.
1
Turn off the inverter and make sure that DC link voltage has dropped to a safe level.
2
Loosen the screw on the power cover then remove the power cover.
