Question 2
Which of the following statements is true about UPS5000 power modules and bypass modules?
A.
The UPSS000-E-200K and UPS5000-E-400K use the same power module and provide the same capacity of 50 kVA but have different numbers of power modules.
B.
For UPSs of the same model but in different power segments, their bypass module capacity is the same.
C.
The power module capacity of both the UPS5000-S and UPS5000-E is 50 kVA. Therefore, the two types of UPS can be used together.
D.
The power modules used in the UPSS000-S-1200K are the same as those used in the UPS5000-E- 200K.

Question 3
In operant conditioning, the subject is free to make responses at any time, So conditioning is measured by the rate of responding. In most other Ways, however, their forms of learning are essentially the same.
A.
When UPSs are connected in parallel, connect loads to the pL terminal.
B.
When a single UPS works and loads are of the same importance, connect all loads to the sL terminal.
C.
When a single UPS works and loads are divided into two levels, connect the primary load to the sL terminal and the secondary load to the pl_ terminal.
D.
When the UPS is overloaded, the loads connected to the sL terminal will be powered off first to ensure continuous power supply to the loads connected to the pj_ terminal.

Question 6
Which of the following statements is false about the ECM of the UPS5000-E?
A.
As a control interface for the entire system, the ECM communicates with each module and provides a bus for communication between the dry contact card and the system control card.
B.
The ECM controls the bypass module to work properly, if one ECM is faulty, the UPS can still work in normal mode but cannot be manually switched to bypass mode.
C.
The ECM ensures equalized output currents between modules so that load power is equally shared.
D.
The ECM provides three types of CAN communication: monitoring CAN communication, intra-rack parallel CAN communication, and inter-rack parallel CAN communication.
