10.2 Real Time Clock (RTC) Battery Replacement
A CR2032 Lithium-Manganese battery to power the inverter’s built-in RTC (real time clock) is
installed on the main PCB. When the battery charge is low, a low battery voltage level warning is
given on the keypad display.
The RTC feature and any other features related to the RTC feature, such as the time event control,
do not work properly when the battery runs out. Refer to the following battery specifications
when a battery replacement is required.
RTC Battery Specifications

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 main 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.
