Unpacking and Installation
2.7 Load Wiring
To ensure that the functions of the PCZ1000A work accurately and reliably, all
wires must be connected correctly to their loads.
2.7.1 Precautions Concerning Wiring
Electric wire used
• Risk of fire. Ensure that the cables used to connect the PCZ1000A to
the equipment under test have sufficient current-carrying capacity
compared to the rated input current of the PCZ1000A.
• Risk of electric shock. To ensure sufficient insulation compared to
the isolation voltage ±500 Vdc, use a reinforced insulation cable
(UL1032 cable or equivalent) for the cables used to connect the
PCZ1000A to the equipment under test.
See Table 2-1 for details of the cables to use to connect to the load input terminals,
and ensure that the cross-section area of the cables is adequate to carry the allowable
current recommended by Kikusui over and above the actual current level to be used.
Also, please use cables with insulation able to withstand temperatures of 75
°
C
or
higher.
