12 PV connection
CAUTION
■
Before connecting or disconnecting the PV cables, make sure the PV switch is
turned off.
■
Make sure the PV cables are connected with the correct polarity.
■
Make sure the open circuit voltage does not exceed the inverter input limit 600 V.
Otherwise, it will cause the inverter damage. If PV open circuit voltage is between
550 V and 600 V, PV over voltage error will occur.
The lead wires from the PV modules are directly connected to Q.HOME CORE. For the connectors (PV1+, PV1-,
PV2+, and PV2-) between the distribution box and the Q.HOME CORE input, MC4 type connectors are used.
12.1 Assembling the PV Connector
Stäubli PV-KBT4/6II-UR, PV-KST4/6II-UR is used for the PV connector.
Note
For information about the PV cable specification, see "6.2 Power Cable Specification" on page 25.
To assemble the PV Connector:
1
Strip the cables.
■
Strip length: 6 to 7.5 mm
2
Crimp the stripped cables using a crimping plier.
3
Check the crimped cables to make sure that:
■
All of the strands are captured in the crimp sleeve,
■
The crimp sleeve is not deformed or missing any portion of the crimp flaps,
■
The crimp is symmetrical in form.
4
Insert the crimped-on contact into the insulator of the male or female coupler until engaged.
■
Usually a “click” sound will be heard once fully inserted.
■
Pull gently on the lead to check that the metal part is correctly engaged.
