Omron H8PS Operation Manual page 9

Precautions for Safe Use
Observe the following items to ensure the safe use of this product.
Environmental Precautions
• Store the H8PS within specified ratings. If the H8PS has been stored at tempera-
tures -10°C or lower, let it stand for 3 hours or longer at room temperature before
turning ON the power supply.
• Use the H8PS within the specified ratings for operating temperature and humidity.
• Do not operate the H8PS in locations subject to sudden or extreme changes in
temperature, or locations where high humidity may result in condensation.
• Do not use the H8PS in locations subject to vibrations or shock. Extended use in
such locations may result in damage due to stress.
• Do not use the H8PS in locations subject to excessive dust, corrosive gas, or
direct sunlight.
• Install the H8PS well away from any sources of static electricity, such as pipes
transporting molding materials, powders, or liquids.
• The H8PS is not waterproof or oil resistant.
Do not use it in locations subject to water or oil.
• The life expectancy of internal components may be reduced if the H8PS is
mounted side-by-side.
• Do not use organic solvents (such as paint thinner or benzine), strong alkaline, or
strong acids because they will damage the external finish.
Usage Precautions
• Install a switch or circuit breaker that allows the operator to immediately turn OFF
the power, and label it to clearly indicate its function.
• Pay careful attention to polarity to avoid wrong connections when wiring
terminals.
• Do not connect more than two crimp terminals to the same terminal.
• Use the specified wires for wiring.
Applicable Wires
AWG24 to AWG18 (cross-sectional area of 0.208 to 0.832 mm
Solid or twisted wires of copper
• Do not connect loads that exceed the rated output current. The output elements
may be destroyed, possibly resulting in short-circuit or open-circuit faults.
• Always connect a diode to protect against counterelectromotive force when using
an inductive load. Counterelectromotive force may destroy output elements,
possibly resulting in short-circuit or open-circuit faults.
• Use the specified cables to connect outputs.
• Do not install input lines in the same duct or conduit as power supply or other
high-voltage lines. Doing so may result in malfunction due to noise. Separate the
input lines from high-voltage lines.
