2.6.4 Connecting Power Cables
The steps of connecting power cables are as follows:

maintenance bypass switch is opened. Attach necessary warning signs to these
switches to prevent unauthorized operation.
2. Open the back door of the cabinet, remove the plastic cover. The input and output
terminal, battery terminal and protective earth terminal are shown in Fig.2-12.
