3. OPERATING GUIDE - CHARGING
E.
MODIFY CONSTANT POTENTIAL
If charging in constant-potential mode (CP),
the constant charging voltage can be
modified. This has to be done before
connecting the battery.
1. Turn on the AC on-off/reset power switch.
2. Turn the Constant Potential Adjust
Trimpot until the desired voltage is
obtained. The voltmeter will display the
voltage as it is being adjusted.
3. Turn off the AC on-off/reset power switch
when
voltage
has been adjusted.
CAUTION: Ensure the unit is turned off
before connecting the battery.
F.
CONNECT BATTERY
Connect the battery DC cable to the battery.
Ensure the connectors are plugged in
completely.
NOTE: The factory-presets are 24.5 and 28.6
volts in constant-potential mode can, if desired,
be modified in step E above.
G.
SWITCH ON MAINS POWER
Turn on the AC on-off/reset power switch. The
voltmeter reads the battery terminal voltage,
the ammeter reads zero. The timer reads 0’s
and its red LED is off.
