4.1.6 Notes
The following points are for general guidance only. If there are relevant local regulations, the local regulations shall prevail.
1. The cable size of the protective earth cable shall be selected according to the AC power failure level, cable
length and protection type. The grounding wire connection must use the shortest connection route.
2. For the cables with large current, parallel connection of small cables can be adopted to facilitate the installation.
3. When selecting the battery cable size, the current value in Table 4.1 on the previous page shall be referred to,
and a maximum voltage drop of 4Vdc is allowed.
4. Do not form coils, so as to minimize the formation of EMI.
4.1.7 Power Cable Connecting Terminal
The rectifier input, bypass input, output and battery power cables are connected to the corresponding terminals shown in
Figure 4.2 on page40.
