Note:
1. The specs are applicable at ambient temperature of 25°C.
2. The battery cable should reach at least +90°C heat durability. It is recommended to use double-insulated copper-core
flame-retardant cable as battery cable
The CSA of the system earth cable should be the same as that of the largest power distribution cable and not less
2
than 1.5mm . The earth terminal is one M5 bolt.
2. Cable specifications of NetSure 211 C45-S2 power supply system
It is recommended to use the RVVZ cables as AC cables. The cable should reach at least +70°C temperature
durability. Select the AC cable Cross-Sectional Area (CSA) according to Table 2-4.
Connector
AC input MCB
The CSA of DC cable depends on the current flowing through the cable, the allowable voltage drop and load peak
current. The recommended load peak current is 1/2 to 2/3 of MCB or fuse capacity.
Select the battery cable CSA according to Table 2-5. Select the load cable CSA according to Table 2-6.
