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).

Operating mode

A-3, b-1, F, toff-1/
ton-1 mode

When power is turned OFF.

Other mode
