(with software version 5110/5120 and newer)
!
WARNING
PRECAUTIONS
1) Read this manual in its entirety before installing or operating the VS616PC5/P5 inverter. This manual applies to inverters with software
versions 5110 and 5120 only and is not intended to be used in conjunction with any other software.
2) Do not connect or disconnect wiring, or perform signal checks while
the power supply is turned ON.
3) The VS-616PC5/P5 internal capacitor may be charged even after the
power supply is turned OFF. To prevent electric al shock, disconn ect all
power before servi cing the inverter . Then wait at least five minutes
after the power supply is disconnected and all LEDs are ext inguished.
4) Do not perf o rm a withstand volt a ge t e st or a megger test on any part
of the VS-616PC5/P5. This electronic equipment uses semiconductors and is vulnerable to high voltage.
5) Do not remove the operator unless the power supply is turned OFF .
Never touch the printed control board while the power supply is
turned ON.
6) The VS-616PC5/P5 is suitable for use on a circuit capable of delivering
not more than 65,000 RMS symmetrical amperes, 480 Volts maximum
(460V class units), 240 Volts maximum (230V cla ss units ).
Failure to observe these and other precautions highlighted in this manual
will expose the user to high voltages, resulting in equipment damage,
serious injury or death.

1.4 MOUNTING
!
CAUTION
PRECAUTIONS
1) When preparing to mount the VS-616PC5/P5, lift it by its base. Never
lift it by the front cover.
2) Mount the inverter onto nonflammable material.
3) The VS-616PC5/P5 generates heat. For the most effective cooling
possible, mount it vertically. For more details, refer to “Dimensions/
Heat Loss” on pages 15 & 16 and “Clearances” on page 17.
4) When mounting units in an enclosure, install a fan or other cooling
device to keep the intake air temperature below 113°F (45°C).
Failure to observe these precautions may result in equipment damage.
Choosing a Location
Be sure that the inverter is mounted in a location protected against the following conditions:
· Extreme cold and heat. Use only within the ambient temperature range:
14 to 104°F (-10 to 40°C).
· Direct sunlight (not for use outd oo rs )
· Rain, moisture
· High humidity
· Oil sprays, splash es
· Salt spray
· Dust or metallic particles in the air
· Corro sive gases (e.g. sulfurized gas) or liqu i ds
· Radioactive substances
· Combustibles (e.g. thinner, solvents, etc.)
· Physical shock, vibration
· Magnetic noise (e.g. welding machines, power devices, etc.)

Notes:
1) The required clearances at the top, bottom, and both sides of the inverter are the same
for both open chassis and NEMA 1 enclosures.
2) For inverter models 25HP and less (230V & 460V), remove the top and bottom covers
to convert NEMA 1 units to open chassis
3) Allowable intake air temperature:
Open chassis:14°F to 113°F (-10°C to +45°C)
NEMA 1:14°F to 104°F (-10°C to 40°C)
4) Whe n mounting units in an enclosure, install a fan or other cooling device to limit the
air temperature within the inverter to below 113°F (45°C).

Wiring
Main Circuit Wiring
Input Wiring
· Molde d-Case Circuit Breaker ( MCCB)
Be sure to connect MCCBs or fuses between the AC main circuit power
supply and VS-616PC5/P5 input terminals L1, L2 and L3, to protect the
power supp l y wi ri ng .
· Ground Fault Interrupter
When connecting a ground fault interrupter to input terminals L1, L2
and L3, select one that is not affected by high frequency.
Examples:NV series by Mitsubishi Electric Co., Ltd. (manufactured
in or after 1988), EGSG series by Fuji Electric Co., Ltd.
(manufactured in or after 1984).
· Magnetic Contactor (MC)
Inverters can be used without an MC installed on the power supply side.
An MC can be used instead of an MCCB to apply the main circuit
power supply. However, when an MC is switched OFF on the primary
side, dynamic braking does not function and the motor coasts to stop.
The load can be operated/stopped by closing/opening the MC on the
primary side. However, frequent switching may cause the inverter to
malfunction.
When using a braking resistor unit, use an MC to break the power supply
side of the inverter in the event of a dynamic braking overload relay trip.
Otherwise, if the inverter malfunctions, the braking resistor unit may be
burned out.
· Terminal Block Connect i on Sequence
Input power supply phases can be connected to any terminal regardless
of the order of L1, L2 and L3 on the terminal block.
· AC Reactor
When conn ecti n g an i nver te r (2 30 V/4 60 V, 25HP or les s) to a large capacity power supply transformer (600kVA or more), or when switching a
phase-advancing capacitor, excessive peak current flows through the input
power supply circuit, which may damage the converter section. In such
cases, install a DC reactor (optional) between inverter ⊕1 and ⊕2 terminals, or an AC reactor (optional) on the input side. Installation of a reactor
is also effective for improving power factor on the power supply side.

Chapter 1 - Receiving & Installation
Wiring
· Surge Suppressor
For inductive loads (i.e. magnetic contactors, magnetic relays, magnetic
valves, solenoids, magnetic brakes, etc.) connected near the inverter,
use a surge suppressor across the coils to limit the transients on the supply lines.
Output Wiring
· Motor Connec ti on
Connect motor lead wires to output terminals T1, T2 and T3. Verify that
the motor rotates in the forward direction (CCW: counterclockwise
when viewed from the motor load side) with the forward run command.
If the motor rotation is incorrect, exchange any two of the motor leads.
· Magnetic Starter
Do not connect a magnetic starter or a magne tic contactor to the output
circuit. If the motor load is connected or di sconnected while the inverter
is running, the inverter overcurrent protective circuitry may trip.
· Thermal Overload Relay
An electronic overload protective function (I
2
t) is incorporated into the
inverter. However, when driving several motors with one inverter, or
when switching between multiple windings of a multiple winding
motor, use an external thermal overload relay(s). In this case, set parameter n034 to “Disabled”.
· Wiring Distance Between Inverter and Motor
If the total wiring distance between inverter and motor is excessively
long and the inverter carrier frequency (IGBT switching frequency) is
high, harmonic leakage current from the wiring will adversely affect the
inverter and peripheral devices. If the wiring distance is long, reduce
the inverter carrier frequency as described below. C arrier frequency can
be set by param et er n054.

· Use ground wiring as specified in “Wire and Terminal Screw Sizes” on
page 25, and keep the length as short as possible.
· Whe n using severa l VS-616PC5/P5 units side by side, groun d the units
