Safety Precautions
• All electrical work must be performed in accordance with local and national electrical codes.
• This product is designed for indoor/compartment installation. It must not be exposed to rain,
snow, moisture, or liquids of any type.
• Use insulated tools to reduce the chance of electrical shock or accidental short circuits.
• There are no user-serviceable parts contained in this product.
• This unit is provided with integral protection against overloads.
• Live power may be present at more than one point since an inverter utilizes both DC (batteries,
PV, etc.,) and AC (utility or generator) power. To reduce risk of electric shock, ensure all DC
and AC wiring is disconnected prior to installing or performing maintenance on the inverter.
Turning off the inverter will not reduce this risk, the inverter must be totally disconnected
from all sources.

• Listed or labeled equipment shall be installed and used in accordance with any instructions
included in the listing or labeling.
• Always verify proper wiring prior to starting the inverter.
• Use only copper wires with a minimum temperature rating of 90°C (194°F).
• AC wiring must be no less than 10 AWG (5.3 mm²) gauge copper wire.
• Battery cables should be no less than #4/0 AWG (107.2 mm²) for 12 and 24-volt systems.
Crimped and sealed copper ring terminal lugs with a 5/16 hole should be used to connect to
the DC terminals on the inverter.
• Torque all AC wiring connections and DC cable connections to the required torque values.
• The inverter must be properly mounted, see Section 2.2 “Mounting the Inverter” in this
manual.
