Precautions for Connection
1、Requirement of the machine cabinet:
The cabinet installation of the system and driver should apply the full-close
dust-proof design. The temperature difference between the inside and outside of the
cabinet should be below 10℃. Heat exchange system is needed if the above condition is
not met. The ambient temperature around the system should be below 45℃. And the liquids
such as lubricant, coolant should be prevented from entering the inside of the system
components.
2、System fixation position:
Since the main cabinet is the control core of the CNC machine, it should be fixed
in priority at a location that has a little temperature rising, little electromagnetic
disturbance. Due to that the large power spindle driver and feed axis driver produce a
huge heating during their running, so the main cabinet and the I/O unit should be fixed
below them with over 100mm clearance as much as possible. Please refer to the appendix
of this manual for their installation drawing dimensions of the system.
3、Power should be supplied to system by isolation transformer.
It is DC24V power supply that
is from power supply box only for CNC control, connecting this DC24V with another device(for
example brake、valve etc. ) is strictly prohibit, otherwise it is very danger!
4、Ground：

！ The machine cabinet must install protective grounding, the demand of grounding must
measure up GB5226.1-2002.It is well grounding that is necessarily for system in working order,
it cannot be in series system of each unit of grounding, it must install ground plate of
cabinet(can use a thick copperplate that thickness is 3mm or more)，The ground resistance
in protective grounding must be 4Ω or less. The cable used for protective grounding must
be of a sufficient cross section for each unit to connect ground plate, Generally the cable
is short-thick, and the color of cable is yellow-green.

5、Wiring：
The signal cables and control cables of weak current should be distributed far away
from the place where heavy current and heavy electromagnetic disturbance exist. They
should be distributed straightly against interference signal that may occur by twisted
cables.
6、Interference inhibition：
Connect shunt RC loop circuit to the AC coil (Fig.1). And the RC loop circuit should
be fixed as near as possible to the inductive load; connect reversely shunt freewheeling
diode to the DC coil (Fig.2); connect shunt surge absorber to the AC motor coil (Fig.3).
