2. Connect three-pin to three-pin socket, do not use the commutator of three-pin to
two-pin.
3. Keep the machine far away from the other electronical-device.
4. Use the cable supplied or appointed by GE and connect it according to the
installation process. For example, separate the power cord from signal cord.

1-4-3 General Notice

1. Only the appointed external devices can connect with this system and cannot affect
EMC capability.
2. Note when doing the modification:
a) Do not change the collocation of this system. As such modification will worsen
EMC capability.
b) Modification of collocation including:
• Modification of cable (length, material, connection and so on.)
• Modification of installation/composition of system
• Modification of configuration/components.
• Modification in the way to fix system/components (turn on or off the cover
board, close the bolt of cover board)
3. Close all the cover boards when operating, if one cover board is on, make it off
before continuing the operation in spite of any reason. It will affect EMC capability
when the cover board is on.

1-4-4 Countermeasures against EMC related-issues

It is usually difficult to resolve EMC problems, it takes a lot of time and cost, and
make the electromagnetism interfere to other device.
1. Keep the system far away from other device, that can decrease electromagnetism
interfere.
2.
Change the relative position between this system to other devices, that can decrease
electromagnetism interfere.
3.
Change the position of other device's power cord/signal cord, that can decrease
electromagnetism interfere.
4.
Change the power supply route of other device, that can decrease electromagnetism
interfere.
