Wiring the Classic
WARNING: Shock hazard. Disconnect the batteries and input power before opening the Classic
front cover
When two or more Classics are paralleled onto one DC Source a blocking diode must be used between
each Classic and the input source to isolate each Classic from the other ones.
The Classic should be wired by a qualified professional and needs to meet all applicable electrical
codes. Always make sure all source and battery circuits are de energized and wait 5 minutes before
working on the wiring in the Classic. The Classic has 2 common neutral (negative) terminals.
Therefore, only one neutral conductor is required to run from the E-Panel and terminate on either (or
both) common neutral terminal. The Positive DC source wire goes to the PV+ Turbine+ screw. The
Positive Battery DC wire goes to battery + terminal. Torque the terminal screws to the specs below.
To connect the wiring to the Classic:
 Ensure the DC source and Battery are disconnected
 Connect a grounding conductor between the Classic and system ground
 Ensure the breaker between the battery and Classic meets UL489 standards.
 Ensure the breaker between the dc source and Classic meets UL1077 standards.
 Connect the DC source and Battery wire to the Classic
 Connect any communications cables or auxiliary input/output wires
 Torque terminal connector screws to the following specs
The Torque specs on the DC terminal connector (big blue terminal connector) are:
 Up to #10 AWG torque to 25-35 inch pounds.
 #8 AWG torque to 30-40 inch pounds.
 #6 AWG or above. Torque to 40-50 inch pounds.
