5. Close and latch the rear door.
Inverter and battery status are indicated on the LED display panel located on
the front of the PrintCart adjacent to the hand grips. The batteries in a new
PrintCart arrives nearly fully charged. Battery state of charge “gas gauge”
shows all LED’s lit, (2 red, 2 yellow, and 2 green). If all of the battery status
LED’s are not lilt, charge the PrintCart prior to use.
Power is available when the inverter is in the auto position; the equipment
may now be switched on. If the connected equipment does not receive power,
perform the following:
• 120V units
Examine the GFCI duplex outlet to the left of the inverter. If the trip
indicator lamp located on the right side of the GFCI is illuminated, the
GFCI has faulted. Reset the GFCI by depressing the RESET button
between the two plugs.
• 230V units
Examine the “Load C/B” (load circuit breaker) located above the inverter
output receptacles. If it extends beyond the mounting more that a couple
of millimeters, it has faulted. Reset the load circuit breaker by pressing it
in.
Close and latch the power compartment door.
Operating Limitations
When the cart is not in service, leave it plugged in to maintain battery charge.
Otherwise, charge the cart battery every 90 days.
CAUTION Recharge the batteries as soon as possible after use. Failure to quickly
recharge batteries can result in permanent battery damage. Batteries
left in a discharged state for extended periods may be so damaged that
they will not accept a charge and recharging them could be dangerous.
Any attempt to recharge partially discharged batteries left for an
extended time requires frequent supervision to ensure that venting or
excessive heating does not occur.
Do not charge a fully discharged battery at a rate greater than 1/10 of the
amp-hour capacity. This cart is equipped with fail safe controls to
prevent full discharge. If the batteries become fully discharged, possibly
due to long term inactivity, switch the inverter/charger to slow charging
mode to revive them. Slow charging prevents further damage to the
battery and reduces the risk of battery out-gassing or destructive
heating if the battery is damaged beyond recovery.
