The following front panel features are available on the CSW2012-X inverter
when the access cover is removed (See Figure 1-2):
Info:
To access and view the AC terminal block and ground termi-
nal, remove the four Phillips screws holding the AC wiring access
cover.
7. AC Entry/Exit Openings
– two 1/2” knockouts are provided to
accommodate the inverter’s AC input and output wiring.
8. AC Ground Connection
– used to connect all AC input and output
grounds. To attach multiple ground wires (i.e., ground wires from the AC
input and output circuits), use a pressure or mechanical connector (i.e.,
ring terminal).
9. AC Input Terminal
– a two-pole terminal block used to connect the
inverter’s AC input wiring. This terminal block allows a service/distribution
panel (main panel) to be wired to the inverter’s input.
10. AC Output Terminal
– this four-pole terminal block is used to connect
the inverter’s AC output wiring. This terminal block
allows a dedicated
panel (sub-panel) to be connected between the inverter’s output wiring
and the AC loads.
The AC 1 output terminals (L1/N1) allow a pass-thru (By-Pass mode)
current of 30 amps. The AC 2 output terminals (L2/N2) are protected by the
inverter’s 20-amp circuit breaker (Figure 1-1, Item 6) which limits the pass-
thru current of 20 amps.
CAUTION:
The inverter’s internal AC transfer relay is rated for
30 amps. The pass-thru current from the input terminal to the AC
1 (L1/N1) output terminals must be no greater than 30 amps or
damage to the internal relay may occur.
Info:
The AC input and output terminals can accept one #14 to
#10 AWG (2.1 to 5.3 mm
2
) CU stranded wire. They use slotted head
screws and have a recommended maximum tightening torque of 5
to 8 lbf-in (0.6 to 0.9 N-m).
