exceeds range of specification or susceptible to rapid temperature changes.
e.g. - Exposure to direct sun

- In the vicinity of a heat source

- Do not use the product in extremely humid or dusty locations. It is extremely dangerous to use the
product with its interior penetrated by water or any other fluid or conductive dust. If the product
must be used in such an environment, install it on a dust-proof control panel, for example.

- Avoid using or storing the product in locations subject to shock or vibration that exceeds range of
specification.

- When transporting the product, take suitable measures to avoid applying shock or vibration directly
to the product. Impact resistance: 15G (11ms) below.

- Use the product in the specified operating condition (temperature, humidity, vibration and shock).

2 Setup

CAUTION

Horizontal installation

Figure 2.12. Installation orientation (Horizontal)

Make sure to gain proper space between the product and devices that generate heat or exhaust air so that
the ambient temperature stays in the range specified in the environment requirement.

Also, the temperature range in the environment requirements varies depending on the
installation orientation, so check the operating temperature range in "Chapter 4 System
Reference".

Recommended installation angle
The recommended installation angle for this product is 0°. The temperature specifications of the product

vary between the case when the installation angle is 90° to the left/right and the case when a plane
installation is used, so check the operating temperature range in "Chapter 4 System Reference".

Ambient temperature
The ambient temperature is decided from the multiple measurement points which are a 50mm-distance

from the case. During the operation, adjust the air current to make certain that the temperatures
measured in the points stay within the specified temperature.

- The product is an open-type device (a device designed to be housed inside other equipment) and
must always be mounted inside a mechanical enclosure having enough strength.

- Note that although the ambient temperature is within the specified range, an operational failure may
occur if there is other device generating high heat nearby; the radiation will influence the product to
increase its temperature.

- Do not install the product into the fully-sealed space except the case in which the internal
temperature is adjustable by equipment such as an air conditioner. Long-term usage might increase
the temperature and lead to a malfunction or other troubles.

- When using the product in a high temperature environment, its life time will be shorten. Perform
the forced air cooling to counteract.

Power Requirements

System requires a clean, steady power source for reliable performance of the high frequency CPU on the
product, the quality of the power supply is even more important.

- If the fluctuation of power supply voltage is beyond the product specifications, connect a constant
voltage transformer.

- If the noise is large, connect an isolation transformer (a noise cut transformer).

- Never bundle, place nearby or in parallel the power supply cable and the input /output signal lines.

- If lightning surge protection is required, connect the surge protective device (SPD).

- Ground this product and the surge protective device (SPD) well away from each other.

- Please select the ones which do not exceed the maximum allowable circuit voltage for the surge
protective device (SPD) at the rise time of the power supply voltage.

- Before you restart the power, give the product for at least one second (or more) of the power OFF
time after PWR-LED is turned off.

- When you use with the CPS-PWD-30AW24-01 (by CONTEC), instantaneous voltage drop allowed
time will be 20 millisecond or less.
