Using Proper DC Cable Termination
The battery end and the inverter end of the wires should have proper
terminal lugs that will ensure a firm and tight connection. Choose lugs to
fit the wire size and the stud sizes on the inverter and battery ends.
The following terminal lugs have been provided for the inverter end:
• 2copperterminallugsforbatterywires
- To accommodate up to MCM/kcmil 250/300 for
G4-2012A and G4-3524A and stud size M8
- To accommodate up to AWG#3/0 for G4-2524A & stud size M8
• 2copperterminallugsforexternalchargerwiresto
accommodate up to AWG#4 & stud size M8
Reducing RF Interference
To reduce the effect of radiated interference, shield the wires with
sheathing / copper foil / braiding.
Taping battery Wires Together
To Reduce Inductance
Do not keep the battery wires far apart. Keep them taped together to
reduce their inductance. Reduced inductance of the battery wires helps
to reduce induced voltages. This reduces ripple in the battery wires and
improves performance and efficiency.
AC Side Connections
WARnInG!
•
In default condition, the neutral of the AC output of the unit
in the “Inverter Mode” gets bonded to the metal chassis of the
unit through the internal “neutral to Chassis Switching Relay”.
In the “Utility / Generator Mode”, the internal “neutral to
Chassis Switching Relay” disconnects the neutral of the AC
output connection from the chassis of the unit. The neutral of
the AC output connection of the unit will get bonded to the
earth Ground through the neutral to earth Ground bond in
the Service entrance / AC output connections of the generator.
•
System grounding, as required by national / Local electrical
Codes / Standards, is the responsibility of the user / system
installer.
