See Chapter 10, Technical Data for specification ranges and limits.
NOTICE: DESIGN AND INSTALLATION RECOMMENDATIONS
Maintaining NEMA4X Rating is essential to assure safe operation of
the inverter. Water ingress is likely to cause a failure that could result
in an unsafe condition. The following are recommended.
✓ Addition of weep holes or any other hole will void the warranty.
✓ All conduit entries must be metallic to prevent propagation.
✓ All conduit entries must be sealed to prevent moisture ingress.
o Sealing conduits at the other end will provide additional
protection – firestop putty may be used.
