The Classic SL 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. This negative conductor should be sized to match the b cable. The
Positive DC source wire goes to the PV+ screw. The Positive Battery DC wire goes to b
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.
HyperVOC ™
HyperVOC is a unique feature the Classic has built in. HyperVOC refers to when the DC Input Voltage
raises above the maximum operating voltage (150V, 200V, 250V, depending on the Classic model).
HyperVOC gives you the flexibility to go up to the maximum operating voltage PLUS the nominal battery
voltage. For example, the Classic 150 has an input voltage rating of 150 operating volts, if the Classic 150
is connected to a 48 volt battery bank, the HyperVOC voltage limit will be: 150V + 48V a total of 198
Volts that the Classic can withstand without damage. When the Classic input voltage rises above 150 volts
it will switch off (stop outputting power). As long as the Classic is in HyperVOC mode, the
microprocessor and all other functions like AUX will continue running. When the input voltage comes
back down below 150v (or the rated operating voltage of the Classic, depending on model) the Classic
will wake up and start charging again automatically. This could happen in a really cold morning with a
system that has a Voltage Open Circuit (VOC) close to the maximum operating input voltage.
Note 1.
A
HyperVOC
message will be displayed on the bottom right side of the Status screen.
Note 2.
Max nominal battery voltage to be added is 48v
