Question 1

In the FusionModule800 grounding solution, each cabinet is connected to the ground bar of the data center.

ATrue

BFalse

Answer : A

Question 2

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.

AWhen UPSs are connected in parallel, connect loads to the pL terminal.

BWhen a single UPS works and loads are of the same importance, connect all loads to the sL terminal.

CWhen 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.

DWhen 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.

Answer : D

Question 3

The power system of a UPS2000-G-15K at a site is three-phase input and single-phase output. After installation, it is found that the mains and bypass inputs are three-phase, the output is single-phase, and the mains and bypass inputs share a power source. Which of the following statements are true about the UPS wiring mode?

AThe wiring mode is incorrect, if the upstream mains input switch is turned on, the UPS will be short-circuited and damaged immediately.

BThe wiring mode is correct. The UPS can start properly.

CThe wiring mode is incorrect. The UPS cannot work in battery mode, but can still work in bypass mode or inverter mode.

DThe wiring mode is incorrect. The correct wiring mode should be single-phase bypass input, three-phase mains input, and one power source.

Answer : A

Question 4

Which of the following statements is true about UPS5000 power modules and bypass modules?

AThe 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.

BFor UPSs of the same model but in different power segments, their bypass module capacity is the same.

CThe power module capacity of both the UPS5000-S and UPS5000-E is 50 kVA. Therefore, the two types of UPS can be used together.

DThe power modules used in the UPSS000-S-1200K are the same as those used in the UPS5000-E-200K.

Answer : A

Question 5

In the FusionModule2000, the skylight actuator can control the rotating skylight in the aisle containment of the modular data center.

ATrue

BFalse

Answer : A

Question 6

Which of the following statements is false about the ECM of the UPS5000-E?

AAs 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.

BThe 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.

CThe ECM ensures equalized output currents between modules so that load power is equally shared.

DThe ECM provides three types of CAN communication: monitoring CAN communication, intra-rack parallel CAN communication, and inter-rack parallel CAN communication.

Answer : B

Question 7

To determine whether the R410A refrigerant meets requirements, compare the internal pressure of the refrigerant with the saturation pressure corresponding to the refrigerant temperature. If the difference between the internal pressure and the saturation pressure is within the range of which of the following, replace the refrigerant?

A0-0.05 MPa

B0.05-0.1 MPa

C0.1-0.2 MPa

D0.25-0.3 MPa

Answer : B
