7.15 Battery Operation Verification
1.
Insure that the Power Supply Module is connected to an appropriate power source and
that the D.C. plug is connected to the D.C Power Input of the Passport.

6.
Remove one of the batteries and verify unit continues to operate.
7. Install the battery that was removed in the previous step and remove the other battery.
Unit should continue to operate without interruption.
7.16 Leakage Current Test
NOTE: The Passport Monitor is not considered double insulated
because it has provisions for grounding via the three
conductor line cord to U-blade ground through the external
supply. The external supply is considered a recognized/
certified component by the UL/CSA and is part of the
monitor. However, the monitor does not have any accessible
exposed conductive metal. The U-blade connection is not
carried through the external supply into the monitor itself,
the DC voltage is only provided. NFPA 99 section 7-5.1.3.2
does not apply because no metal on the monitor can
become line energized. The Passport was evaluated with
the external supply by UL and CSA with no grounding
impedance verification. If you check U-blade resistance, the
safety analyzer will read “open”.
