Introduction
The EV Inverter series is state of the art design using the latest control and power technologies.
It is designed to operate and control 3Ø induction motors in the range of 0.25 to 3hp and voltage
class of 230 or 460VAC. The inverter can operate either in V/ f or open loop vector mode settable
via programming. There are two sets of parameters, FBasic, and CAdvanced, allowing for
flexible control in many different applications. The membrane keypad in combination with a 3 digit
7 segment display allow for ease of programming and monitoring.
An optional communications module can be used for control and parameter setting using the
MODBUS RTU protocol. The EV has been designed with easy access to the input power, output
motor, and control terminals.
Before proceeding with the set-up and installation please take time to review this manual to
ensure proper operation and above all else, personnel safety.
SAFETY FIRST!
Section 1 - Safety Precautions
1.1 Preface
To ensure your safety and to avoid damage to the equipment,please read this manual
thoroughly before making any connections. Should there be any questions or problems in using
the product that cannot be resolved with the information provided in this manual, contact your
nearest representative for further guidance.
The inverter is an electrical product and as such, lethal voltages are present at various points. For
your safety, there are symbols as shown below that appear in this manual to remind you to pay
attention to safety instructions on handling, installing, and operating the inverter. Please follow the
instructions to insure the highest level of safety.
DANGER Indicates a potential hazard that could cause death or
serious personal Injury.
CAUTION Indicates that the inverter or the mechanical system might
be damaged.
Danger
After the power has been turned OFF, wait at least 5 minutes until the charge
indicator extinguishes completely before touching any wiring, circuit boards,
or components.
!1.2 Receiving and Inspection
Caution
All inverters have been tested for functionality prior to shipment. Please check the following
when you receive and unpack the inverter:
Check the nameplate to insure the model and capacity of the inverter are the same
as those specified in your purchase order.
Check for any damages as the result of transportation. If there is damage, do not
apply power, and immediately contact your representative.

1.3 Installation and Pre-operation
Caution
The inverter should be installed in a dry and dust-free area.
The inverter should be installed on a nonflammable surface such as metal.
The inverter may be operated up to an altitude of 1000m. Above 1000m it must be
de-rated. (Please consult factory)
If several inverters are to be placed in the same enclosure, additional cooling may be
needed to keep the surrounding temperature below 50°C to avoid overheating or
possible fire.
Do not connect T1, T2, and T3 terminals of the inverter to the AC power supply.
CMOS ICs on the inverter‘s main board are susceptible to static electricity. Do not
touch the main circuit board without proper precautions.
Do not perform dielectric tests on parts inside the inverter as the high voltage will
easily destroy semiconductor parts.
Wiring size and insulation type, as well as placement of the inverter, should conform
to applicable codes for a particular installation.
Control wiring should be kept separate from power wiring and cabling. In some
applications it may be necessary to use shielded cable for the control wiring and / or
the power cabling to avoid performance issues.
Danger
Do not modify any internal wiring, circuits, or parts. Connect the ground terminal of
the inverter properly. For 200V class Rg =< 100Ω, 400V class Rg =< 10Ω.
1.4 During Power ON
Caution
The display will flash the input voltage for about 2 seconds when power is applied.
Danger
To avoid damage to the control circuitry resulting from transient voltages, do not plug
or un-plug any connectors or connect or disconnect any wiring to or from the inverter
when power is present.
Do not change out parts and or check signals on circuit boards during the inverter
operation.
When power interruption to the inverter is momentary, the inverter has sufficient
power storage to ride through and continue operation. However, when power loss
interruption is longer than 2 seconds (the larger the horsepower, the longer the time);
the inverter does not have enough stored power to maintain control. Therefore, when
power is restored, the inverter restart is controlled as follows:
1 -Will not automatically run after restart if Run Command Source parameter
F04=000 keypad (Factory Default).
2 -Will not automatically run after restart if Run Command Source parameter
F04=001 external terminal (switch) is off.
3 -Will automatically run after restart if Run Command Source parameter
F04=001 external terminal (switch) is on and parameters F41=000. (Auto
Restart after power loss)
When removing or installing the keypad operator, turn OFF power first, and follow the
instruction diagram to avoid improper operation.
