SECTION 6 PREVENTIVE MAINTENANCE, CARE AND CLEANING

Checking Leakage Current
Leakage current is a primary indicator of electrical shock hazard to personnel making
contact with any exposed outer surface of the equipment. Each A-2000 BIS Monitor is
carefully checked at the factory to verify that leakage current meets the UL2601 and
IEC601-1 safety standards.
The A-2000 should be checked routinely for leakage current at least once a year.
Always have the leakage current checked after a saline or blood spill, or immediately
after a major surge in the house electrical system and after every time the monitor case
has been opened.
Keep in mind that liquids such as saline and Ringer’s as well as blood are all excellent
conductors of electricity. Avoid touching any part of the system with wet hands. Always
work with clean, dry hands.
WARNING!
ELECTRICAL SHOCK HAZARD: THE MANUFACTURER’S
INSPECTION OF THIS APPARATUS VERIFIED THAT THE GROUND
LEAKAGE CURRENT AND THE PATIENT SAFETY CURRENT WERE
LESS THAN THE SPECIFIED LIMITS ESTABLISHED BY THE
APPLICABLE SAFETY STANDARDS. AS A MATTER OF SAFE
PRACTICE, THE INSTITUTION SHOULD CONDUCT PERIODIC TESTS
TO VERIFY THESE CURRENTS. WHENEVER AN EVENT SUCH AS
SPILLAGE OF BLOOD OR SOLUTIONS OCCURS,
RE-TEST BEFORE FURTHER USE.
6.3 FUSE REPLACEMENT
The A-2000 contains two inline fuses (1.25A, 250V, 5x20mm Aspect P/N 430-0006)
within the AC power input module located at the rear of the monitor. In the unlikely
event that a fuse needs to be replaced, one can access these fuses as follows:
1. The fuse holder is part of the AC power input module on the rear of the monitor and
is located just above the power cord input connector.
2. Disconnect the AC power cord from the wall socket and from the rear of the monitor.
3. Locate the plastic locking tabs securing the fuse holder in place.
4. Insert the tip of a ball point pen or similar tool, into the slots provided to release the
plastic locking tabs allowing the fuse holder to spring out of its locked position.
5. Remove and replace both fuses.
6. To re-install the fuse holder, simply insert the fuse holder and press in with finger
until the plastic locking tabs engage, securing the fuse holder in place.
WARNING!
REPLACE FUSES ONLY WITH ONE OF THE FOLLOWING PARTS:
Aspect P/N 430-0006, 1.25 Amps, 250V, 5x20mm
Littelfuse 217 Series, 1.25 Amps, 250V, 5x20mm
Wickmann 193 Series, 1.25 Amps, 250V, 5x20mm
ALWAYS REPLACE BOTH FUSES TOGETHER, EVEN IF ONLY ONE
HAS FAILED.
