Note: The specs are applicable at ambient temperature of 25° C. If the temperature is higher than this, the CSA of the cable should
be increased
To prevent the air switching capacity is too large, the load overload does not work. Recommended the capacity of the
air switching is up to 1.5 ~ 2 times of the load peak.
The CSA of the system grounding cables should be consistent with the largest power distribution cables. The CSA
value is no less than 25mm
AC and DC power distribution interface definition see Table 2-4.

2.3 Mechanical Installation
Note
1. The cabinet or rack the subrack power supply system installed in must provide fireproof and electric protection casing, or
install in cement or other difficult to burn, at the same time and other combustible materials to keep enough distance.
2. For the convenience of maintenance, users should maintain a clearance of 800mm at the front of the power supply system.
3. Subrack cannot be installed against the wall, it must leave enough space for heat dissipation.
Installed on battery bracket
1. Fix the subrack power system to the battery bracket through the connectors with M6 bolts, as shown in Figure 2-1.
