PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.
 Disconnect AC input power before connecting any wiring to the AC motor drive.
 Even if the power has been turned off, a charge may still remain in the DC-link
capacitors with hazardous voltages before the POWER LED is OFF. Do not touch
the internal circuits and components.
 There are highly sensitive MOS components on the printed circuit boards.
These components are especially sensitive to static electricity. Take anti-static
measures before touching these components or the circuit boards.
 Never modify the internal components or wiring.
 Ground the AC motor drive by using the ground terminal. The grounding method
must comply with the laws of the country where the AC motor drive is to be
installed.
 DO NOT install the AC motor drive in a location
with high temperature, direct
sunlight or inflammable materials or gases.
 Never connect the AC motor drive output terminals U/T1, V/T2 and W/T3 directly
to the AC mains circuit power supply.
 After finishing the wiring of the AC motor drive, check if U/T1, V/T2 and W/T3 are
short-circuited to ground with a multimeter. Do NOT power the drive if short circuits
occur. Eliminate the short circuits before the drive is powered.
 The rated voltage of power system to install motor drives is listed below. Ensure
that the installation voltage is in the correct range when installing a motor drive.
For 115V models, the range is between 85–132 V.
For 230V models, the range is between 170–264 V.
For 460V models, the range is between 323–528 V.
 Refer to the table below for short circuit rating:
Model (Power) Short circuit rating
115V 5 kA
230V 5 kA
460V 5 kA

Only qualified persons are allowed to install, wire and maintain the AC motor
drives.
 Even if the three-phase AC motor is stopped, a charge with hazardous voltages
may still remain in the main circuit terminals of the AC motor drive.
 The performance of electrolytic capacitor will degrade if it is not charged for a long
time. It is recommended to charge the drive which is stored in no charge condition
every 2 years for 3~4 hours to restore the performance of electrolytic capacitor in the
motor drive. Note: When power up the motor drive, use adjustable AC power source
(ex. AC autotransformer) to charge the drive at 70%~80% of rated voltage for 30
minutes (do not run the motor drive). Then charge the drive at 100% of rated voltage
for an hour (do not run the motor drive). By doing these, restore the performance of
electrolytic capacitor before starting to run the motor drive. Do NOT run the motor drive
at 100% rated voltage right away.

III

Pay attention to the following precautions when transporting and installing this
package (including wooden crate and wood stave)
1 If you need to deworm the wooden crate, do not use fumigation or you will
damage the drive. Any damage to the drive caused by using fumigation
voids the warranty.
2 Use other methods, such as heat treatment or any other non-fumigation
treatment, to deworm the wood packaging material.
3 If you use heat treatment to deworm, leave the packaging materials in an
environment of over 56°C for a minimum of thirty minutes.
Connect the drive to a three-phase three-wire or three-phase four-
wire Wye
system to comply with UL standards.
If the motor drive produces a leakage current of over AC 3.5mA or over DC 10mA
on the Protective Earthing conductor, the minimum specifications required of the
Protective Earthing conductor to be installed have to comply with the national, local
laws and regulations or follow IEC61800-5-1 to do grounding.
MH300 series is designed for the applic
ation of general industrial environment.
Non-linear load causes harmonic current, if the drive uses with public low voltage
(e.g. the power supplies to houses), then you have to assemble an appropriate
restraint equipment (e.g. isolation transformer or inp
ut reactor) to restrain the
interference may be caused. Contact with Delta for more information.
NOTE:
In the pictures in this manual, the cover or safety shield is disassembled only when explaining the
details of the product. During operation, install the top cover and wiring correctly according to the
provisions. Refer to the operation descriptions in the manual to ensure safety.
The figures in this instruction are only for reference and may be slightly different depending on your
model, but it will not affect your customer rights.
The content of this manual may be revised without prior notice. Consult our distributors or download

1-5 RFI Jumper
The drive contains Varistors / MOVs that are connected from phase to phase and from phase to ground to
protect the drive against mains surges or voltage spikes.
Because the Varistors / MOVs from phase to ground are connected to ground with the RFI jumper,
removing the RFI jumper disables the protection.
(1) In models with a built-in EMC filter, the RFI jumper connects the filter capacitors to ground to form a
return path for high frequency noise in order to isolate the noise from contaminating the mains power.
Removing the RFI jumper strongly reduces the effect of the built-in EMC filter.
(2) Although a single drive complies with the international standards for leakage current, an installation
with several drives with built-in EMC filters can trigger the RCD. Removing the RFI jumper can help,
but the EMC performance of each drive is no longer guaranteed.
Non-built-in EMC filter models
Frame A–I
Loosen the screw and remove the RFI jumper (as shown below). Fasten the screw again after you remove
the RFI jumper.

Isolating main power from ground:
When the power distribution system of the drive is a floating ground system (IT Systems) or an
asymmetric ground system (Corner Grounded TN Systems), you must remove the RFI jumper. Removing
the RFI jumper disconnects the internal capacitors from ground to avoid damaging the internal circuits and
to reduce the ground leakage current.
Important points regarding ground connection:
 To ensure the safety of personnel, proper operation, and to reduce electromagnetic radiation, you must
properly ground the drive during installation.
 The diameter of the cables must comply with the local safety regulations.
 The shields of shielded cables must be connected to the ground of the drive to meet safety regulations.
 The shields of shielded power cables can only be used as the ground for equipment when the above
points are met.
 When installing more drives, do not connect ground terminals of each drive to the ground with single
point and series connection, but connects with single point and parallel connection. See the following
pictures.
Pay particular attention to the following points:
 Do not remove the RFI jumper while the power is on.
 Removing the RFI jumper also disconnects the built-in EMC filter capacitors. Compliance with the EMC
specifications is no longer guaranteed.
 Do not remove the RFI jumper if the mains power is a symmetrical grounded power system in order to
maintain the efficiency for EMC circuit.
 Do not remove the RFI jumper while conducting high voltage tests. When conducting a high voltage
test to the entire facility, you must disconnect the mains power and the motor if the leakage current is
too high.
Floating Ground System (IT Systems)
A floating ground system is also called an IT system, an ungrounded system, or a high impedance /
resistance (greater than 30 Ω) grounded system.
 Disconnect the RFI jumper.
 Check whether there is excess electromagnetic radiation affecting nearby low-voltage circuits.
 In some situations, the transformer and cable naturally provide enough suppression. If in doubt, install
an extra electrostatic shielded cable on the power supply side between the main circuit and the control
terminals to increase suppression.

Chapter 1 IntroductionMH300

 Do not install an external EMC filter. The EMC filter is connected to ground through the filter capacitors,
thus connecting the power input to ground. This is very dangerous and can easily damage the drive.
Asymmetric Ground System (Corner Grounded TN Systems)
Caution: Do not remove the RFI jumper while there is power to the input terminal of the drive.
In the following four situations, you must remove the RFI jumper. This is to prevent the system from
grounding through the RFI and filter capacitors and damaging the drive.
You must remove the RFI jumper
1. Grounding at a corner in a triangle configuration

2. Grounding at a midpoint in a polygonal
configuration

Internal grounding through RFI capacitors, which reduces
electromagnetic radiation. In a symmetrically grounding
power system with higher EMC requirements, you can
install an EMC filter. As a reference, the diagram on the
right is a symmetrical grounding power system.
