E5−H High Performance Universal Inverter
Wiring
The wiring must be conducted by qualified electricians. Otherwise, electric shock may
happen or inverter damage.
Before wiring, confirm that the power supply is disconnected. Otherwise, electric shock
may happen or fire.
The PE terminal must be reliably grounded, otherwise, the inverter enclosure may
become live.
Please do not touch the main circuit terminals. The wires of the main circuit terminals
must not contact the inverter enclosure. Otherwise, electric shock may happen.
The connecting terminals for the braking resistor are
connect terminals other than these two. Otherwise, fire may be caused.
The leakage current of the inverter system is more than 3.5mA, and the specific value of
the leakage current is determined by the operation conditions. The inverter and the
motor must be grounded to ensure the safety.
Wiring
The three−phase power supply cannot connect to output terminals U/T1, V/T2 and
W/T3, otherwise, the inverter will be damaged.
It is forbidden to connect the inverter output terminals to the capacitor or LC/RC noise
filter with phase lead, otherwise, the internal components of the inverter may be
damaged.
Please confirm that the power supply phases, rated voltage are consistent with those
indicated by the nameplate, otherwise, the inverter may be damaged.
Do not perform dielectric strength test on the inverter, otherwise, the inverter may be
damaged.
The wires of the main circuit terminals and the wires of the control circuit terminals shall
be laid separately or in a square−crossing mode, otherwise, the control signal may be
interfered.
The wires of the main circuit terminals shall adopt lugs with insulating sleeves.
The sectional area of inverter input and output cables should be selected according to
the inverter power.
When the cables between the inverter and the motor is longer than 100m, it is
suggested to use output reactor to avoid the inverter failure caused by the overcurrent of
the distribution capacitor.
The inverter equipped with a DC reactor must be connected with a DC reactor between
the terminals of ○ 1 and ○
