7-4 Precautions
Wiring Wiring input lines in the same conduit as power lines or other high-voltage
lines may result in malfunction due to noise. Wire the input lines separately,
away from lines carrying high-voltages. In addition, make the input wiring as
short as possible and use shield lines or metal wiring conduits.
Mounting Dense mounting may result in a reduction in the service life of internal parts.
Tighten the two mounting screws on the Adaptor. Tighten them alternately, a
little at a time, so as to keep them at an equal tightness.
The 700-HX panel surface is water-resistant (conforming to NEMA 4 and
IP66). In order to prevent the internal circuit from water penetration through
the space between the timer and operating panel, attach a waterproof gasket
between the timer and installation panel and secure the waterproof gasket with
the 700-HN130 flush-mounting adapter.
Operating Environment • Use the product within the ratings specified for submerging in
water, and exposure to oil.
• Do not use the product in locations subject to vibrations or
shocks. Using the product in such locations over a long period
may result in damage due to stress.
• Do not use the product in locations subject to dust, corrosive
gases, or direct sunlight.
• 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).
