Step 3
Insert the positive and negative power cables into corresponding cable glands.
Step 5
Insert crimped power cables into corresponding housings until you hear a "click" sound.
The power cables snap into place.

Step 4
Insert the stripped positive and negative power cables into the positive and negative
metal terminals respectively and crimp them using a clamping tool. Ensure that the cables
arecrimped until they cannot be pulled out by force less than 400 N, as shown in Figure 4-27.
1. Positive power cable
2. Negative power cable
Step 6
Reinstall cable glands on positive and negative connectors and rotate them against the
insulation covers.
Step 7
Insert the positive and negative connectors into corresponding DC input terminals of
the Sunny Horse Series until you hear a "click" sound, as shown in Figure 4-28.

Follow-up Procedure
To remove the positive and negative connectors from the Sunny Horse Series, insert a
removal wrench into the bayonet and press the wrench with an appropriate strength, as
shown in Figure 4-29.
4.6 Safety check
Before the inverter operation, need to be examined for the photovoltaic array, Check Open
circuit voltage of the each PV array whether accord with the requirements.
Photovoltaic array
−
Ensure Open circuit voltage of the each PV array accord with the requirements;
Ensure that the positive and negative polarity is correct.
−
Sunny Horse Series DC connect
Use the multimeter to check the DC side voltage and current;
Check the DC cable
，
Note the positive and negative poles cannot be reversed, Consistent
with the positive and negative pole of photovoltaic array, measured each input Open circuit
voltage
Compare the voltage, if the difference is greater than 3%, PV array line may be a fault
Sunny Horse Series AC connect
Ensure the AC breaker of the inverter is off
Check the inverter phase with grid is connected properly, Check the voltage of each phase is
within a predetermined range, if possible, Measure the THD, If the distortion is serious, the
inverter may not work.

Caution
Before removing the positive and negative connectors, ensure that the DC
SWITCH is OFF.
