resistance with respect to the outside of the cable. The allow-
able current in Table 3.1 "Load Considerations" show the cur-
rent capacities that can be flowed through a heat-resistant PVC
wire (single wire) with a maximum allowable temperature of
60
°
C when the wire is stretched horizontally under an ambient
temperature of 30
°
C. The current capacity should be lower
when the heat resistant temperature of the PVC wire is lower,
the ambient temperature is higher than 30
°
C or the heat radia-
tion is degraded due to the use of bundled wires.
Taking measures against noise
It is better to make heat radiation as great as possible to allow a
larger current to flow, when wires having the same heat-resis-
tant temperature are installed. For measures against noise in the
load cables, however, installing the + (pos.) and – (neg.) output
lines side by side or bundling them together is more effective
against unwanted noise. The Kikusui-recommended currents
shown in Table 3-1 "Nominal cross-sectional area of cables and
allowable currents" are allowable current that have been
reduced in consideration of the potential bundling of load
cables. Use these values as a guideline when installing load
wires.
Voltage rating of the load cable
Use a load cable with a higher voltage rating than the isolation
voltage of the PMC-A. For the isolation voltage of each model,
see Chapter 7 "Specifications".
