EMI
The EMI might be coupled from the source to the L1000-A through the following coupling mechanisms:
Capacitive coupling
•
•
Inductive coupling
Radiative coupling
•
Common impedance coupling
•
Conductive coupling
•
To prevent EMI, take the following actions:
Take measures against interference from the power grid.
•
Do not use the L1000-A together with the grounding equipment or lightning-prevention equipment
•
of power equipment, and keep the L1000-A far away from them.
•
Keep the L1000-A far away from high-power radio launchers, radars, and equipment with high
frequency or high current to make sure the EMI levels do not exceed the compliant range.
Use electromagnetic shielding when necessary.
•
Lightning protection
To protect the L1000-A from lightning better, do as follows:
Make sure the chassis is correctly grounded. For how to ground the L1000-A, see
•
L1000-A."
Make sure the grounding terminal of the AC power receptacle is correctly grounded.
•
•
Install a lightning protector at the input end of the power supply to enhance lightning protection
capability. For more information, see
