6.2 Connection on the AC Side
Ÿ Do not place inflammable and explosive materials around the WIT
Inverter.
Ÿ High voltages may cause electric shocks and serious injury. Please do
not touch the inverter in operation.
Ÿ Only qualified and trained electrical technicians are allowed to
perform operations. Technicians must observe instructions in this
manual and local regulations.
Ÿ Before connecting cables, ensure that the DC switches on the WIT
Inverter are OFF. Turn off the switches and breakers on the AC side and
the battery side. Otherwise, the high voltages of the WIT Inverter may
result in electric shocks.
Ÿ Each WIT Inverter must be equipped with an AC circuit breaker.
Multiple WIT Inverters cannot connect to the same AC circuit breaker
(not applicable to off-grid mode).
Ÿ Please do not connect loads between the WIT Inverter and the circuit
breaker.
Ÿ After connecting the cables, apply the fireproof mud evenly on the
waterproof silica gel pad inside the AC junction box to prevent water
from entering into the box.
Ÿ If the cable is thick, do not shake the cable terminals after tightening
them. Otherwise, the loose connection may cause overheating that
will damage the device. Ensure that the terminals are properly
connected before powering on the WIT Inverter.
1> Ensure the grid voltage and the grid frequency are within the acceptable range;
Preparation:
2> Disconnect the DC switches and the breakers on the AC side and the battery side.
A circuit breaker needs to be installed on the AC side, ensuring a safe disconnection
between the WIT Inverter and the upstream input when an exception occurs.
