The Pacemaker™ static welding inverter has a RAM battery for data retention and clock-buffering at power interruption/disconnection. The battery has a limited life span (about 5 years) that decreases especially without power supply (controller off). To prevent loss of data, the battery must be replaced early enough.
The parts can be ordered in our webshop or with prepared form.
