Commissioning the RPS1600-A
• Before powering on the RPS1600-A, check the AC input with a
multimeter set to Ohms to eliminate any short circuit.
• Upon powering on the RPS1600-A, if the run LED is on, and the
alarm LED and fault LED is off, the output is normal; if the alarm LED
or fault LED on the front panel is on, the RPS1600-A works
abnormally; if none of the run LED, alarm LED, and fault LED is on,
an AC mains problem has occurred.
For more information about the LED description, see “ LEDs description .”
Replacing a fuse
Follow these steps to replace a blown fuse:
1. Check that the RPS1600-A is powered off.
2. Turn the fuse cover anticlockwise to remove the fuse cover.
3. Remove the blown fuse and insert a spare fuse into the fuse cover.
Verify that the fuse is in good contact with the bottom of the fuse
cover.
4. Insert the new fuse together with the fuse cover into the fuse
receptacle on the chassis, and turn the fuse cover clockwise to lock
it in place.
