Operating Voltage Setting and Fuse Replacement (Continued)
Processor Power Supply Redundancy
This comprises an additional 4U-high box mounted on top of the processor rack. The
standard processor rack power connectors are unused; power input is via two IEC
mains connectors, as shown below. These should be fed from two independant
sources, of which one is recommended to be a UPS.
Adjacent to each connector is a fuse holder. Fuse ratings are as follows:
Voltage Rating SSL Part No.
100/120V 5A(T) 35FET350
220/240V 2A(T) 35FEG320
The PSURedundancy package is
supplied configured for use at the
specified operating voltage - for
reconfiguration instructions,
contact SSL Product Department.
Power Supervisor Unit
The Power Supervisor Unit Power Input Module is shown below. To the right of the
module are four small holes, beside each of which is engraved one of the available
operating voltages. The hole corresponding to the current setting is filled by a light
coloured spigot; the three remaining
holes are clear. The unit is shown here
set for 240V operation. Adjust the setting
if necessary, and check the fuse rating
(1A Time Delay, SSL Part No. 35JFT310)
before applying power.
To change the voltage setting or check the fuse, remove the IEC lead and use a
narrow bladed flat screwdriver to prise open and remove the panel to the right of the
mains input connector. The panel assembly holds the fuseholder, and, to the right, the
voltage selection assembly. If the voltage setting is incorrect, use a pair of thin-nosed
pliers to grasp and remove the voltage selector assembly from the right of the Power
Input Module fuseholder
receptacle. The assembly
comprises a small PCB
and a nylon locating
spigot, as shown on the
right.
Set the nylon spigot so that, when the assembly is held with the spigot vertical (as
shown), the desired operating voltage appears along the bottom of the PCB. Replace
the assembly in the Power Input Module, ensuring that the arrow on the top of the
spigot is pointing towards one of the four arrows in the module.
Replace the panel and ensure that the nylon spigot projects through the hole
corresponding to the desired voltage setting, as shown above.
