CAUTION
CAUTION

1. Installation Precautions
DANGER
zIf an emergency stop circuit, interlock circuit, or similar circuit is to be
formulated, it must be positioned external to this module. If you do not
observe this precaution, equipment damage or accident may occur when this
module becomes defective.
zHigh voltages may cause electrical shock hazards. If you disconnect/
connect the module or cable with the power supply switched on, you may
inadvertently touch a power supply terminal and receive an electric shock or
the equipment may become damaged due to short circuit or noise. Switch off
the power supply before disconnecting/connecting the module or cable.
CAUTION
zUse the module in an environment specified in the catalog and manual.
If you use the module in an environment where the module is subjected to high
temperature, high humidity, dust, corrosive gas, vibration, or impact, a risk of
electric shock, fire, or malfunction may result.
zObserve the installation procedure stated in the manual.
If the module is improperly installed, it may drop, become defective, or
malfunction.
zDo not allow wire cuttings or other foreign matter to enter the module.
The entry of foreign matter in the module may result in a fire or cause the
module to become defective or malfunction.
zWhen the module is to be positioned at a location where it may become wet
with water, place it within a drip-proof enclosure to prevent it from becoming
defective.
zThe module may become defective due to a high temperature, which may
result from heat dissipation failure. It may also malfunction due to
electromagnetic interference from nearby equipment. For heat dissipation
and electromagnetic radiation minimization, provide the specified clearances
among the module, its enclosure, and neighboring equipment.

CAUTION
zThe degree of temperature rise varies depending on how the module is
mounted. The mounting intervals specified in the manual should be used as
a guide only. While a test run is conducted after completion of mounting,
measure the temperature near the module to check whether it is within the
specified range. If the measured temperature is beyond the specified range,
increase the mounting intervals or provide forced air cooling with a cooling fan.
zDust or other foreign matter might accumulate on the connector, resulting in
poor contact. Immediately after the module is unpacked, perform the
mounting and wiring procedures.
zTo prevent the module from being damaged, observe the following precautions
when you mount or demount the module:
•Before mounting the module to the mount base connector, check that the
connector pins are properly aligned and not bent, broken, or soiled with dirt
or the like.
•Ensure that the module is parallel to the mount base vertical surface as
shown below when mounting. If you connect a module to or disconnect it
from its connector while it is tilted, the connector pins may become damaged.
•If the mount base is positioned overhead due to the employed enclosure
structure, use a stepladder or the like and mount the module squarely. If
you mount the module obliquely, the connector may become damaged.
[Bad example] [Good example]

Mount base

REQUIREMENT
zFasten the mount base to a vertical surface. Fastening the mount base to a
horizontal surface lessens the heat dissipation effects and allows the
temperature to rise, thereby rendering the module defective or incurring
component parts deterioration.
zBefore installing the module, discharge any static buildup from your body
because static electricity may render the module defective.
zProperly tighten the screws. If they are inadequately tightened, malfunction,
smoke emission, or combustion may occur.
PROHIBITION
Do not disassemble or modify the module. Failure to observe this precaution
may result in a fire or cause the module to become defective or malfunction.

2. Wiring Precautions
DANGER
zSwitch off the power supply before making connections to the terminal block.
Making connections with the power supply being switched on may incur
electrical shock hazards.
zElectric shock hazards exist so that you might suffer burns or become
electrocuted. Further, the system might malfunction due to noise
interference. Therefore, ground the line ground (LG), frame ground (FG), and
shield wire (SHD).
REQUIREMENT
zInsulate the mount base from the enclosure. To keep the mount base
insulated, avoid removing the insulation sheets that are supplied with the
mount base.
zThe LG is a ground terminal for power supply noise. The FG and SHD are
ground terminals for the noise in the remote I/O, communication module and
other external interface lines. To avoid interference between the ground
terminals, separately ground the LG and FG.
CAUTION
zIf the input voltage for the power supply module is within the specified range
but close to the upper or lower limit, you should conclude that an input power
problem exists, and ask the power supply facility manager to conduct an
inspection.
zBe sure that the power source for supplying power to various modules is rated
as specified. The use of a differently rated power source may cause a risk of
fire.
zOnly qualified personnel should be allowed to make cable connections.
Incorrect wiring connections may cause a risk of fire, malfunction, or electric
shock.

REQUIREMENT
zBefore supplying power to the equipment, thoroughly check the wiring
connections.
zBefore making power supply wiring connections, make sure that no voltage is
applied to the power cable. Immediately after completion of power supply
wiring, be sure to install the terminal cover.
zEnsure that the communication, power supply, motive power, and other cables
are routed apart from each other. It is essential that the inverter, motor,
power regulator, and other motive power cables be routed at least 300 mm
away from the other types of cables. Also, be sure that the communication
and motive power cables are routed within separate conduits.
zProvide with protect elements, such as a fuse and/or a circuit protector, in an
external power supply for short circuit protection. Use the suitable protect
elements for suited rating.
PROHIBITION
To avoid noise-induced malfunction, do not bundle the 100 VAC/100 VDC wiring
and network cable together, but route them at least 100 mm away from each
other.

3. Operating Precautions
REQUIREMENT
The module could fire or fail under heat. When the temperature in the enclosure
exceeds 48°C, the maximum output current flowing through the power module is
limited. Its current is limited to 5.85 A at 55°C. Allowing for the environment in
which the module is installed, install a cooling fan in the enclosure or limit the
number of modules installed in it. For more information, refer to “USER’S
MANUAL R70 BASIC MODULE (manual number SVE-1-111)” or “USER’S
MANUAL BASIC MODULE (manual number SVE-1-100).”
DANGER
zIf the module emits smoke or foreign odor, immediately switch off the power
supply and investigate the problem cause.
zDo not perform any installation, wiring, handling, or internal modification
procedures other than stated in this manual. In no event will Hitachi be
responsible for personal injury or death or any damage to Hitachi's product or
peripheral equipment arising out of the use of such an unauthorized
procedure.
zWhile the power is applied, never touch a terminal strip or connector pin. If
you touch a terminal strip or connector pin while the power is applied, you may
receive an electric shock.
CAUTION
zBefore changing the program, generating a forced output, or performing the
RUN, STOP, or like procedure during an operation, thoroughly verify the safety
because the use of an incorrect procedure may cause equipment damage or
other accident.
zWhen you switch on the power supply, follow the specified sequence. Failure
to follow the specified sequence may cause equipment damage or other
accident.
zDo not use a transceiver, cellular phone, or similar device near the module
because module malfunction or system failure may occur due to noise.
zTo avoid malfunction, ensure that the power supply is switched on and off at
intervals of longer than 1 second.

CAUTION
zThe contents of the memory may become damaged due, for instance, to a
module failure. Be sure to make a backup of important data.
zBefore constructing a system, creating a program, or performing a similar
procedure, thoroughly read this manual to become familiar with the contained
instructions and precautions. If you perform any incorrect procedure, the
system may malfunction.
