System Configuration
2–6 976-0043-01-01
Clearance for fire
safety Please keep all readily flammable materials (cloth, paper, straw, plastic
etc.) at a minimum clearance of 24" (60 cm.) from the top surface (when
wall mounted) and 12" (27 cm.) from either side surface and the front of
the
Sine Wave Plus . Readily flammable materials refers to instantly
combustible substances such as cloth, paper, straw, and plastic sheeting.
Ventilation Requirements
Location Install the inverter in a well-ventilated area/enclosure for proper
operation. The inverter’s thermal shutdown point will be reached sooner
than normal in a poorly ventilated environment resulting in reduced peak-
power output and surge capability as well as shorter inverter life.
Requirements Provide a minimum clearance of 3 inches (12 inches is preferred) around
the top and 6 inches at the AC- and DC-side of the inverter for ventilation.
A fan-forced, fresh-air vent (on the inverter’s AC side) allows cool air to
enter the unit and exit from the DC-end of the inverter. Ensure that this
vent is not obstructed with foreign objects, such as dirt and dust and that
the minimum clearances are met.
Airflow clearance All air ventilation openings should have 6 inches of clearance and there
should be no nearby cover over the top of the unit. This is to prevent
warm, exhausted air from the unit being drawn back into the unit, which
could cause premature shutdown due to overheating.
Screening The unit is equipped with screening to prevent insects and rodents from
entering. This screening needs to be checked and cleaned regularly from
the outside to prevent dust buildup.
Grounding Considerations
The following points should be taken into consideration when planning
how to properly ground the system, whether or not you’re installing a new
system or integrating new parts into an older system.
DC System Grounding
The Sine Wave Plus can be used in either a positive or negative grounded
system. However, unless you are installing the inverter into an existing
positive grounded system (i.e., a telecommunications system), it is highly
recommended to use negative grounding.
Important: The grounding requirements vary by country and by
application. All installations must comply with national and local codes
and ordinances. Consult local and/or national codes and the NEC for
specific grounding and bonding requirements for the desired installation.
