Improper maintenance of the SSPB Up-Converter unit may void the warranty.
9.1 PREVENTIVE MAINTENANCE
This product requires minimum maintenance, which consists of visual inspection and cleaning.
WARNING:
The person performing maintenance of this equipment must have training
and knowledge of both the product and safety requirements and safety issues related to the
equipment. Read and practice the safety guidelines at the beginning of this manual (
Section 1

at page 6).
9.2 MECHANICAL PREVENTIVE MAINTENANCE
Mechanical preventive maintenance consists of verifying the condition of all mechanical parts,
with the AC power switched off. Perform the following inspection:
1. Check all connectors and plugs for evidence of damage and improper seating. Replace
defective connector plugs and reset any that are dislodged.
2. Inspect the electrical wiring for signs of discolored, broken or poor insulation. Repair or
replace if necessary.
3. Inspect all waveguides for discoloration, cracks, loose connectors and improper sealing.
Tighten or replace waveguides as required.
4. Check for other defects such as, wear, breakage, deterioration, fungus, excess moisture and
mounting integrity.
9.3 COOLING FAN CHECK
The SSPB Block Up-Converter unit is forced-air cooled, using a single fan. The cooling fan is
located at the bottom shroud of the SSPA. Verify that the fan is operating smoothly. Any suspect
noise may indicate wear and fan will have to be replaced. Check for debris or dust in the fan
intake and in all openings on the unit. This may reduce the efficiency of the cooling system. The
fan should be replaced every two years, in order to ensure the proper cooling of the unit.
WARNING:
Do not come in contact with any electrical assembly while power is
applied.
