Power Equipment Access
Gain access to the power equipment through tool latchable doors on the front
and rear of the PrintCart. Inside the power compartment, the power system is
divided into two separate replaceable subpallets. The battery subpallet (BSP)
contains the two batteries, the main fuse battery and the quick disconnect
battery. The power equipment subpallet (PESP) contains the inverter/charger,
a GFCI duplex outlet (120V version), and a power quick disconnect cable to
the BSP. These subpallets can be removed independently and are held in
place by a set of restraining bolts located on the outside of the PrintCart near
the bottom edge.
NOTE: It is not necessary to move the equipment subpallet inside the frame
to access the power equipment for inspecting or resetting safety
devices (breakers or GFCI). Simply open the door and all devices are
visible and readily accessible.
If greater access is required, such as for servicing equipment or replacing
batteries, the subpallets can be completely removed (see “Power Equipment
Subpallet (PESP) Removal” below).
Make sure that the screws joining the two subpallets are removed. Some
factory configurations are shipped with the PESP bolted to the BSP; they
must be removed as a single unit and the mating bolts removed before the
subpallets can be handled separately. To remove the pallet as a single unit,
disconnect the PESP side as indicated below but do not remove it. Prepare
the BSP and remove the entire unit as indicated in the BSP removal process
(see “Battery Subpallet (BSP) Removal” on page 39).
NOTE: It is not necessary for the subpallets to be joined for proper operation
and they may be replaced in the PrintCart as separate units.
Power Equipment Subpallet (PESP) Removal
1. Make sure the mating screws joining the two subpallets are removed.
2. If PrintCart is plugged into an AC outlet, disconnect the plug from the
outlet.
3. Open the rear access door on the inverter side.
4. Shut off the inverter/charger main switch located on the front of the
inverter.
5. Disconnect the PrintCart equipment power cords either in the
CFCI (120V) or in the face of the inverter (230V).
6. Disconnect the blue inverter display data cable from the inverter.
