Immunity: EN 61000-6-2
Applying power.
Emissions: EN 61000-6-4
• As soon as power is applied, the orange colour “SUPPLY” ➊ neon will illuminate.
Troubleshooting.
• If the orange neon fails to illuminate, check the voltage is present to terminals L and N and within the
working limits of the device
• Also check the external protection fuse has not blown.
