*1. The listed capacities of fuses and breakers (or leakage protectors) are only for reference.
*2. When the machine is working at the places where are moist or on the iron plate or stand, please be
sure to install leakage protector.
*3. Because the voltage of the outputs of the cutting power source is higher than 300V, please be sure to
use connecting cables of which withstand voltage is same as that of input side ones.
*4. To connect the cables with the outputs of the cutting power source, one piece of round cable plug
KDP16d-K is provided as the accessory of power source. The range of cross-section for connecting
cable is 16~25 mm
2
. When less than 16 mm
2
, please add the cross-section area of joint cable to be
connected with the plug up to the minimum cross-section area.
Note: please follow the regulations listed below to avoid any damage of parts, unstable arc and overheat
or damage of the machine.
●
The fluctuation range of input: the allowable rated input voltage is
－
20 %
～＋
20 %.
●
When the generator is used, the rated input capacity should be two times of cutting power source or
higher. The generator should be equipped with compensating coils.
●
The wiring of input side: please equip each cutting power source with one fuse switch or non-fuse
breaker (or leakage breaker) of which capacity complies with the rated one of the cutting power
source.
●
Please select the proper breaker (or leakage breaker) which is applicable to electric distribution, such
as cutting, electric motor or transformer.
