Clenergy SPH Installation and Operation Manual
5.
For SPH50 & SPH60, connect AC wires as follows:
Disassemble the AC output female socket.
Connect AC wires to connection socket as indicated:
Strip the wire sheath and conductor insulators the minimum amount
necessary to insert the wires into the connection pins.
Insert Line wire to
1
, Neutral wire to
N
and Ground wire to pin .
Fully tighten the wire clamp screws in each connection pin.
Assemble the socket again. Insert the whole socket into the inverter.
Twist the coupling ring to receptacle on inverter. Make sure it is perfectly
matched and tightly fastened.
Do not connect the AC power at this time
Step 3: Connect to the PV array (DC)
1.
Make sure the maximum open circuit voltage (V
oc
) of each PV string is less
than 550V UNDER ANY CONDITION for SPH15, SPH20 & SPH40 and 600V
for SPH50 & SPH60.
2.
Ensure that the DC supply wires to the inverter are disconnected from the
PV strings. We recommend that a disconnect switch or optional Solar
Concentrator with disconnect is fitted between the PV array and the inverter.
When making connections to the PV array outputs, the PV panels must be
completely covered with shade material and the outputs must be shorted
together and to earth ground. Always follow local and national codes and
regulations for installation work on PV panels.
3.
Verify with a DC voltmeter that there is no voltage between the positive and
