gas, oil mist and dust with the altitude below 2,000m ; please use this Inverter
by reducing the capacity if the altitude is above 2,000m.
5.
The air shall be clean and dry. No humidity is allowed, for instance, the
condensation in wire conduit enters the box. To avoid the above, the wire
conduit shall be installed at the top of this Inverter.
2.3 Electrical Part
All the connections of this Inverter shall satisfy the national regulation (NEC) and
relevant local regulations. See the nameplate of this Inverter and motor for the
voltage and current.
2.4 Safety Cautions
1)
This Inverter can input either AC or DC voltage and one input circuit breaker
(generally the circuit breaker with heat protection or the fusible isolation switch)
between the power and this Inverter shall be set. If the wire noise or
instantaneous voltage becomes too large, isolation transformer or wire reactor
can be used to provide this Inverter with input power. If the solar battery is
used to provide power to this Inverter, please always bear in mind to select the
proper voltage grade of photovoltaic battery. The working voltage grade of the
solar battery array is recommended to be 300V-350VDC and 325VDC is the
best voltage. The input open-circuit voltage of this Inverter shall be no higher
than 450VDC; otherwise, it easily causes damage to this Inverter.
2)
Prior to electrical connection, it is a MUST to cover the solar battery array by
lightproof materials since the array will generate high voltage under the direct
sunshine, finally causing personal injury and death.
3)
It is not allowed to start/stop the water pump by alternatively making and
