34 PMC-A
3.2.1 Load Cable
• To prevent the possibility of fire, use a load
cable with sufficient current capacity with
respect to the rated output current of the PMC-
A.
• To prevent the possibility of electric shock, use
a load cable with a higher voltage rating than the
isolation voltage of the PMC-A.
For the isolation voltage, see chapter 7, “Specifi-
cations”.
Current capacity of the load cable
Load cables must be rated to carry the maximum rated output
current of the
PMC-A. If their current rating exceeds the maxi-
mum rated output current, the cable will remain intact even if
the load is short-circuited.
Table 3-1 Nominal cross-sectional area of cables
and allowable currents
When there is a long distance to the load, use as thick a line as
possible, more than recommended.
Dependence of allowable cable current on the maxi-
mum allowable insulator temperature
The temperature of a cable is determined by the resistance loss
due to the flowing current, ambient temperature and the thermal
