Installation
The programmable controller employs electronic circuit and processor technologies. Note the following in
particular:
●
When constructing a system, make sure that conditions including the maximum rating, operating power supply
voltage range, heat dissipation characteristics, and installation conditions are within the guaranteed operating
range described in this manual. Hitachi bears no responsibility for failures or accidents that arise from use of the
product outside the guaranteed range.
Even when using the product within the guaranteed range, you must consider the predicted failure rate and
failure mode of the product. You can then implement system measures such as making the system failsafe so
that operation of the Hitachi product will not cause personal injury, fire, and other consequential damage.
●
The Programmable Controllers (PCs
#
) in which the CPU unit and PI/O units are installed are neither fireproof,
dustproof, nor waterproof. Install the PCs in steel cabinets that are fireproof, dustproof, and waterproof (see
Figure 1-1).
#:
PCs means the programmable controllers in their entirety including the CPU unit and PI/O units.
●
Use the S10VE in an environment that is within the specifications explained in Chapter 3. To ensure long-term
stable operation, we recommend that you use the product at room temperature and normal relative humidity (15
to 35°C and 45 to 85% RH). Using the product in a high-temperature or high-humidity environment or an
environment where the temperature varies widely over the course of a day leads to a reduced service life.

WARNING
●
The S10VE is an open-type device. To avoid electric shock, make sure to install it in an enclosure.
Notice
●
There is a potential for failure if PCs are not installed in a waterproof cabinet.
●
Static electricity might damage a module or cause it to malfunction. Discharge any static electricity
from your body before touching the equipment.
●
The system is not designed to withstand constant vibration or shock. If the system is installed in a
location subject to such conditions, isolate the system from sources of vibration or shock, or take anti-
vibration measures such as the use of anti-vibration rubber mounts.
