Precautions
Insulation
Publication 700-UM002A-EN-D - July 2001
•
Separate the input signal devices, input signal cables, and the
product from the source of noise or high-tension cables producing
noise.
•
Separate the product from the source of static electricity when
using the product in an environment in which a large amount of
static electricity is produced (e.g., forming compounds, powders,
or fluid materials being transported by pipe).
•
Organic solvents (such as paint thinner), as well as very acidic or
basic solutions might damage the outer casing of the timer.
•
Use the product within the ratings specified for temperature
and humidity.
•
Do not use the product in locations where condensation may
occur due to high humidity or where temperature changes
are severe.
•
Store at the specified temperature. If the 700-HX has been stored
at a temperature of less than –10°C, allow the 700-HX to stand at
room temperature for at least 3 hours before use.
•
Leaving the 700-HX with outputs ON at a high temperature for a
long time may hasten the degradation of internal parts (such as
electrolytic capacitors). Therefore, use the product in combina-
tion with relays and avoid leaving the product as long as more
than 1 month with the output turned ON.
T
There is no insulation between power supply and input terminals.
Basic insulation between power supply and output terminals.
Input and output terminals are connected to devices without exposed charged
parts.
Input and output terminals are connected to devices with basic insulation that
is suitable for the maximum operating voltage.
