Ultralife CH0004 - Manual (Page 9)

3 OPERATION
This section provides a basic operational description of the CH0004 battery charger and its
assemblies/major components.
3.1 Grounding Connections
The CH0004 should be grounded to reduce risk of electric shock. The CH0004 is equipped with an
electric cord having an equipment-grounding conductor and a grounding plug. The plug must be
plugged into an outlet that is properly installed and grounded in accordance with all local codes and
ordinances.
3.2 AC Power Cord Connections
If the plug will not fit into the outlet, have a proper outlet installed by a qualified electrician. A
temporary adapter can be used to connect plug to a two-pole receptacle if a properly grounded
outlet is not available. (See Specifications chapter for input power capabilities of the CH0004).
WARNING: Never alter AC cord or plug provided. Improper connection can
result in a risk of an electrical shock. The temporary adapter should only be
used until a properly grounded outlet can be installed by a qualified
electrician.
WARNING: Before using adapter, ensure the center screw of outlet plate
is grounded. The green colored rigid ear or lug extending from adapter
must be connected to a properly grounded outlet. If necessary, replace
original outlet cover plate with a longer screw that will secure adapter ear
or lug to outlet cover plate and make ground connection to outlet.
3.3 Battery Selection, Charging and Charge Cycle
The CH0004 will charge two batteries at one time (including different battery chemistries or two of
the same). Each battery’s type will automatically be detected when placed on the charger. The
CH0004 charge module allows the unattended recharge of batteries. The module also assures a
safe and effective recharge of the battery. The charger has a built-in timer to shut off the CH0004 to
prevent the battery from being overcharged. The recommended batteries are listed in the table that
follows.
The typical charge cycle for the three types of batteries listed below assumes a fully discharged
battery for the charge cycle. Note these are average (approximate) times and are listed to show a
reasonable time frame for the charge cycle.
