*1 Cannot be driven by the inverter.
*2 Allowable range of voltage fluctuation is 2.2kW; -10 to 6%, 3.7kW to 22kW; ±10％.
Allowable range of frequency fluctuation is ±1％. Allowable simultaneous fluctuation of
voltage and frequency is 10% as the sum of the absolute values of them. For both
cases, however, the characteristics and the temperature rise of motor are independent
of the rated values.

Installation

1. Confirmation before installation

Measurement of insulation resistance
Measure the insulation resistance between the ground and the grounding wire and between
phases using a megger in a state that the motor and the cables (excluding the power source
connection section) are immersed in water. If the insulation resistance at the respective sections
is 20MΩ or more, there is no problem. During the measurement, keep the power source
connection section of cables distant from the ground.

On handling and installation work of the pump, assure safety by confirming the
mass and the shape of the pump referring to the appearance this instruction
manual, drawing, the catalogue, and other materials. There are dangers of
dropping the pump and the injury of worker.
Never execute the operation of the pump and the mounting work of parts in a
lifted position. That type of work is dangerous causing dropping the pump and
injury of workers.
Do not damage, break, machine, forcefully bend, stretch, or twist the power
cable, bind the power cable into a bundle, or place a heavy load on the power
cable. Those kinds of handling cause fire and electric shock
The handling and installation work of the pump shall be done only by a
qualified technician in accordance with the applicable legal standards. Unless
follow the rule, the work becomes illegal and there is a possibility of inducing
accident such as fire and injury.
Apply repair painting at an interval depending on the use environment. Depending on the
use environment, there may be generated rust at threaded sections, machined sections
with rust-proof coating, rust-proofing sections, etc.
