3.3 Wiring of 1+1 parallel MBP(standard version)
1+1 parallel MBP (standard version) terminal block (TB) layout is as below:
Notes:
1. AC input TB: N/N/N/mL1/ bL1/ mL2/bL2/ mL3/bL3/PE (‘m’ is main input,’b’ is bypass
input)
2. AC segment 1 (Not programmable): PE/N/N/N/L1/L2/L3
3. AC segment 2 (Programmable): N/N/N/L1/L2/L3/PE
4. UPS1 TB ports
5. UPS2 TB ports
This section outlines the 8 different possible modes of input/output wiring applications. Below is
a list of copper busbars and a label plate available for the different connection modes.
To gain access to the terminal blocks, it is only necessary to remove the terminal block’s top
cover, without removing the whole box.
