MAINTENANCE
CAUTION These servicing instructions are for use by qualified personnel only. To reduce risk of
electric shock, do not perform any servicing other than that contained in the Operating Instructions
unless you are qualified to do so. Refer all servicing to qualified service personnel.
Replacing the Cooling Fans.
It is possible to replace the two cooling fans (which are fitted on a common plate ) at the rear of the
frame without disconnecting any cables from the frame. Although it is possible to perform this
operation with the frame still powered, DO NOT DO THIS,
as the frame is likely to overheat with no
cooling airflow.
The sequence is as follows.
1.
Disconnect the power cord connected to the frame
2.
Use a cross-head screwdriver to slacken the two captive screws that hold the fan mounting plate
onto the rear side of the frame.
3.
Slide the fan mounting plate backwards to free the retaining tabs.
4.
Lift the fan mounting plate clear.
5.
While supporting the weight of the fan and mounting plate, reach in through the mounting plate
hole and disconnect the fan power connector.
6.
Replace the fans with a Crystal Vision supplied replacement part to ensure adequate cooling and
continued fire protection. Be sure to fit the finger guards on both sides of the fan/mounting plate
assembly.
7.
Reconnect the fan power connector
8.
Fit the fan mounting plate tabs into the slots in the frame rear side. Be careful to position the fan
wiring so that it will not touch the fan blades when the fan is in its final position.
9.
Engage the two captive screws that hold the fan mounting plate onto the rear side of the frame.
Fully tighten the screws with a cross-head screwdriver. Check that the screws are too tight to be
undone without a screwdriver.
10.
Reconnect the power supply cords.
Replacing the mains input fuses
The mains input fuses are fitted inside the IEC 320 connectors at the rear of the frame. A spare fuse is
also stored inside the connector. The fuse can only be accessed when the power cord is disconnected.
The sequence is as follows: -
1.
Disconnect the power cord from the rear of the frame.
2.
Using a flat bladed screwdriver or similar tool gently lever out the fuse drawer from the relevant
IEC connector using the tab visible at the bottom of the connector depression.
3.
Remove the defective fuse and replace with either the spare fuse or with a 5A, 250V time delay
fuse.
4.
Replace the fuse drawer and reconnect the power cords.
If a fuse blows repeatedly this indicates a fault either in the associated power supply module or
elsewhere. Return the frame and/or power supply to the manufacturer or dealer for repair.
