The non-intelligent MCB distribution module and non-intelligent hot-pluggable MCB distribution module are
used with the basic unit for common distribution to achieve common power distribution function, with no
distribution circuit monitoring or intelligent management.
The installation and service procedures of the four output distribution modules are the same. Refer to 2.4.6
Installing Power Module And Output Distribution Module and 10.4.4 Service Procedures Of Output Distribution
Module.
Intelligent MCB distribution module
The intelligent MCB distribution module uses hot-pluggable terminals to connect the UPS output busbar to
facilitate installation. The intelligent MCB distribution module in standard configuration provides eighteen
25A/1P MCBs and provides 18 branches of built-in current detection components and switch state monitoring
circuit to acquire and report the current, voltage and state of each MCB.
Intelligent hot-pluggable MCB distribution module
Except that the built-in MCBs are hot-pluggable, the intelligent hot-pluggable MCB distribution module is
completely the same as the intelligent MCB distribution module.
The intelligent hot-pluggable MCB distribution module uses built-in hot-pluggable MCBs. Therefore, with no
need to turn off the whole distribution module, you can regulate the phases of each MCB or replace each MCB
to adjust the branch capacity. Hence, load distribution can be adjusted in equipment operation.
Non-intelligent MCB distribution module
Except that the non-intelligent MCB distribution module does not provide branch monitoring function, it is
completely the same as the intelligent MCB distribution module.
Non-intelligent hot-pluggable MCB distribution module
Except that the non-intelligent hot-pluggable MCB distribution module does not provide branch monitoring
function, it is completely the same as the intelligent hot-pluggable MCB distribution module.
Configuration of MCBs
The preceding four types of output distribution modules all provide eighteen 25A/1P MCBs in standard
configuration. In addition, the MCB configurations provided in Table 8-7 are also available for users' selection.
