6.7.2 Assembling the PV Connectors
High voltage may be present in the inverter!
•
Ensure all cables are voltage-free before performing electrical operations.
•
Do not connect the DC switch and AC circuit breaker before finishing electri-
cal connection.
SUNGROW provides corresponding PV connectors in the scope of delivery for
quick connection of PV inputs. To ensure IP65 protection, use only the sup-
plied connector or the connector with the same ingress of protection.
step 1
Strip the insulation from each DC cable by 7 mm–8 mm.
step 2
Assemble the cable ends with the crimping pliers.
1: Positive crimp contact
2：Negative crimp contact
step 3
Lead the cable through cable gland, and insert the crimp contact into the insulator until it
snaps into place. Gently pull the cable backward to ensure firm connection. Tighten the
cable gland and the insulator (torque 2.5 N.m to 3 N.m).
