WIRE AND CABLE SAFETY
Proper wire type and size is required for all installations. Use only UL-listed Class B or Class C wire
rated for 300 volts and 75ºC or higher. Use stranded wire for the battery circuit and solid or stranded
wire for the AC and Ground circuits.
Copper wire is recommended instead of aluminum due to its ease of use, superior conductivity,
strength and thermal expansion properties.
WARNING: SHOCK HAZARD
•
Installations must be performed by a qualifi ed person trained in electrical safety
procedures (minimum qualifi cation).
• All wiring must comply with local electric code requirements.
• Ensure all sources of
input
are disconnected before connecting
ANY
cabling.
WARNING: RISK OF FIRE
All over-current protection devices and wiring must be sized properly, in accordance with
US National Electric Code (NEC) or the local regulations of the country of installation.
WARNING: FIRE HAZARD
A risk of fi re may exist if a 120 Vac power source is wired incorrectly to 120/240 Vac
panel containing multi-wire branch circuits.
MOUNTING, CLEARANCE, AND LOCATION SAFETY
WARNING: EXPLOSION/FIRE HAZARD
Do not install in a confi ned area where battery gases can accumulate. Battery gases can
create an explosion or fi re hazard if ignited by a spark. Ensure the enclosure is ventilated
well enough to disperse any accumulated gases.
Do not install over an easily combustible surface, since the heat sink may get hot under
certain operating conditions.
CAUTION: EQUIPMENT DAMAGE
• Do not mount in zero-clearance compartment. Overheating may result. Ensure
adequate space around the components to ensure suffi cient ventilation around the
equipment.
• Locate the SureSine on a surface that is protected from direct sun, high temperatures,
corrosive fumes, and water.
• Ensure the mounting surface is strong enough to support the weight of the inverter as
well as any other devices that may be attached to it. It may be necessary to reinforce
the surface with plywood to provide additional support for the equipment.
