Chapter 4 PrintCart Safety Features
• Der Kontakt zwischen positiven und negativen Anschlüsse ist
unbedingt zu vermeiden (Kurzschluss). Kurzschlüsse können Akkus
dauerhaft schädigen und einen Brand oder Verletzungen
verursachen.
• Den Akku keinesfalls an den Ausgangsleitungen fassen, um ihn zu
entfernen oder anzuheben. Fassen Sie den Akku stets am Gehäuse
oder an den integrierten Griffen.
• Akkus den lokalen Vorschriften entsprechend entsorgen. Bleiakkus
keinesfalls im Hausmüll oder in Behältern für Industrieabfälle,
sondern zur Vermeidung von Umweltbelastungen als Sondermüll
entsorgen. Für unsachgemäße und illegale Entsorgung können
empfindliche Strafen verhängt werden.
California Proposition 65

PrintCart Safety Features
The PrintCart is equipped with numerous electrical safety devices to interrupt
electrical power should electrical malfunctions or overloads occur. These
devices are designed to protect both the power equipment and the operator.
They are located in the power compartment and can be accessed through the
front and rear access doors using a screw driver or coin.
NOTE: Access to the power compartment should be limited to specifically
trained and authorized personnel.
The 12VDC battery input to the inverter is protected with a 100-amp flat lug
type input fuse. It is bolted to the battery subpallet on top of the batteries and
is covered by a snap-on plastic cover which must remain in place when the
service disconnect is connected. The fuse has no visible indicator of its
condition, and operability must be confirmed with an electronic meter.
The 12VDC power to the upper display/control is provided through a two wire,
16 gauge cable bolted directly to the front battery. This cable includes an
automotive type ATC blade fuse adjacent to the positive battery terminal to
protect the circuit.
CAUTION Prior to accessing the display panel, unplug the quick disconnect to
prevent any electrical shorts during access.
The AC input is protected by two circuit breakers, both mounted on the
inverter. There is a breaker for the charger portion of the inverter/charger
subsystem located immediately to the right of the inverter fan shroud (same
for 120V and 230V models). It is 8 Amperes for 120V charger and 3/5
Amperes for the 230V charger. The second breaker differs in capacity,
location, and purpose between the 120V and 230V units, as follows:
