body.
4.1 Electrical gas connections
a) Power requirements: 380V, 50HZ, laser electrical connections can be found in
the laser specification.
b) Carefully reading the attached machine tool electrical schematic diagram;
According to the laser cutting machine power wiring diagram wiring.
c) Check the total power and various power open action is sensitive.
d) Check the equipment power wiring is correct or not, as shown in the electrical
wiring diagram.
e) Check the total power open or not and other power open or not (e.g., host, laser
machine) must meet the capacity of drawing marked.
f) The wire diameter of power cord, ground wire and the zero line shall not be less
than the power wire diameter on the wiring diagram.
g) Check ground wire of power cord is connected or not.
h) Check the entire high voltage wire terminal (especially the input and output point
of power transformer) are reliable, strong, all of the plug and whether the board
connection is reliable.
Caution:
The power cord’s ground wire must be reliable
grounding. Otherwise machine tool electrical signals within
the tank will be disturbed and will be dangerous if leakage
4.2 The connection of the water cooling machine

-Cooling water: Do not contain mineral water, distilled water or deionized water
(Don
’
t use mineral water);
-The valve and pipe: All are stainless steel or high pressure rubber hose, cannot use
galvanized material, pipe joint use stainless steel clip.
