2. Integral 13.2 Volt Battery Pack
The 13.2 VDC Nickel Metal Hydride
Battery Pack has been specially manufactured for the WC-9UW Yoke, and no
attempt should be made to replace or operate this unit with one manufactured
by others, as it will void it’s Class 1, Division II status, and could cause it to
fail at pressure. When operating the WC-9UW in a Hazardous Environment,
the unit must be removed to a
Safe Area
, for battery Testing or Charging. A
Safe Area is defined as an environment where no risk of explosion exists
(e.g. Facility Offices).
Battery Pack Assembly
When installing the Battery Pack, after charging, cleaning, or maintenance, fit
the Switching Module into the connector in the bottom of the Junction Tube.
Ensure the Urethane Spring is positioned in the bottom of the Junction Tube,
and line up the Connectors in the bottom of the Junction Tube and on the
Switching Module. Carefully slide the Battery Pack into the Junction Tube,
feeling
the mating connectors together. Install the retaining fasteners,
followed by the Plunger Assembly.
Battery Testing
The Battery is tested with the WC-9UW Battery Voltage Meter. The meter is
equipped with a load resistor, so a true measure of the Battery Voltage can
be attained. To test the Battery Voltage, insert the Battery Voltage Meter into
the connector cast into the Battery Pack. The Battery Meter provides a
general reading of the Voltage, but also provides the operator with a general
indication of the Battery Capacity or an indication of how much longer the unit
