● Attention, check point before operation and in operation
This control device is careful treatment because it is containing a backup battery internally to maintain
program data and monitor data at a power OFF.
1. Please avoid the place which to need the store of the long term is as follows.
1-1. the place which the high temperature and direct light
1-2. the place which the relative humidity is high
1-3. the place with an inflammable and attack gas
1-4. the place which a humidity change is extreme and the dew is formed
1-5. the place which the impact comes to add with the vibration
2. If disjoint and carry the P.C.B, it is careful about the subject following
2-1. To avoid the break of a backup battery, Do lest it should touch directly to aluimum sheet
2-2. To make lest the IC should be destroyed power-failure, do lest possible hand should touch to the
component of PCB.
2-3. To transport, use a vinyl packing paper to become a static electricity protect processing.
3. Check point before operation
3-1. The each connected part must be connected so that it is strong.
Exmple) a connection list of gift of an each part and a linking part of a cooling and high voltage
system
3-2. Cooling water and compressing air observe at this manual and must maintain so that is regular.
3-3. Remove the impurities of the AIR FILTER inside.
3-4. The change of an input power source is the toe in extreme place so that a welding condition unstable,
the rate of voltage change must link ±10％ within.
3-5. The welding transformer installs in near to a power source (the fitness 30m within).
If it is far and goes the size from the transformer because of voltage change is strong and can not get
the setting current, it must do sufficient attention.
3-6. the place to give the equipment the vibration and which a surrounding temperature is over 40℃,a
corrosiveness and exploiveness gas must forbid an absolute install in dangerous place to happen.
