Note [1]: The value is valid only if the conductors of the PE cable and AC power cable use the
same material. If the materials are different, ensure that the conductor cross
-
sectional area of the
PE cable produces a conductance equivalent to that of the area S/2. The specifications of the PE
cable are subject to this table or calculated according to IEC 60364
-5-54.
Note [2]: You are advised to use a soft cable to prevent poor terminal contact due to the bending
stress of the cable.
Note
[3]: For some models, the outer diameter of a single-core cable ranges from 14 mm to 36
mm based on the label in the maintenance compartment.
Note [4]: For some models, when the OT/DT terminal is crimped as shown in the following figure
and the rubber baffle plate of the AC wiring terminal is 112 mm, the maximum conductor cross
-
sectional area of the single
-core cable can be 400 mm
