9.0 SYSTEM SERVICE
This section of the manual contains the information for Fuse replacement, System Maintenance,
System Repairs, and Technical Support.
9.1 FUSE REPLACEMENT
The AC Power input module contains two (2) fuses that protect the unit from excessive power
loads and power line fluctuations. The module is located on the back of the back panel of the unit.
(Refer to Section 4.1 System Overview and FIGURE 4-1, item #8 for fuse location)
If a power surge occurs, these fuses may need to be replaced. Always replace these fuses with
the exact same fuse rating (5 x 20 mm 250V T 5.0A) fuses. These fuses are also available from
Medical Technical Products, LP (MTP) part # 430-2215-002.
