INSTALLING THE MODULES
Orient the module vertically such that the white card ejector is on the bottom. Align the card with the card
guide corresponding to the slot number where you installed the rear panel plate. Carefully slide the
module into the frame and press it completely into the rear panel connectors. Make sure that the
connectors are fully seated in the rear panel.

REMOVING THE MODULES
Press the card ejector down to release the module. Grasp then the card using the card ejector and pull
the module out from the frame. As the card ejector goes past the front extrusion, you will have to pull it
with slightly more force. Carefully place the module in a safe place, free from static discharge.
4. SERVICING
INSTRUCTIONS
CAUTION – These servicing instructions are for use by qualified service personnel
only. To reduce risk of electric shock do not perform any servicing instructions in
this section of the manual unless you are qualified to do so.
4.1.
CHANGING THE FUSES
The fuse holder is located inside the power entry module. To change the fuses, pull out the fuse holder
from the power entry module using a small screwdriver. The fuse holder contains two fuses, one for the
line and one for the neutral side of the mains connection. Pull out the blown fuse and place a fuse of the
correct value in its place. Use time delay 5 x 20 mm fuses rated for 250 Volts with a current rating of
4 amp. (T4AL250V) For your convenience there are spare fuses located in the vinyl pouch in the front of
this manual. Carefully reinsert the fuse holder into the power entry module.
Check that the line fuse is rated for the correct value marked on the rear panel.
Never replace with a fuse of greater value.
4.2.
REPLACING THE POWER SUPPLY
Each power supply is a complete assembly and includes the power supply cooling fan and one frame
cooling fan. In the event that the power supply or one of the fans malfunctions, you will need to replace
the power supply assembly with a spare one while the failed assembly is being repaired.
Do not run the frame for extended periods of time with one of the power supplies
removed. Proper cooling of the frame requires both power supplies to be inserted
into the frame, or one power supply and a 500PS-FM power supply blank panel.
