Load wiring
If the wiring that you use for the load has a high resistance, the voltage will drop significantly
when current flows, and the voltage at the load input terminals may fall below the minimum
operating voltage. Using the following table as a reference, select wiring whose nominal
cross-sectional area is as thick as possible.
A wire’s temperature is determined by the resistive loss based on the current, the ambient
temperature, and the wire’s external thermal resistance. The following table shows the
current capacity of heat-resistant vinyl wires that have a maximum allowable temperature of
60
°
C when one of the wires is separated and stretched out horizontally in air in an ambient
temperature of 30
°
C. The current must be reduced under certain conditions, such as when
vinyl wires that have a low heat resistance are used, when the ambient temperature is 30
°
C
or greater, or when wires are bundled together and little heat is radiated.
WARNING
• Improper use of load wires may lead to fire. Use load wires whose capacity is
adequate for the PLZ-4WH’s rated output current.
• Possible electric shock. Use load wires whose rated voltage meets or exceeds the
PLZ-4WH’s isolation voltage. For details on the PLZ-4WH’s isolation voltage, see
Chap.8 "General specifications".
CAUTION
• Use a load wire with sufficient diameter for the current as well as non-flammable or flame-
resistant cover.
