Safety Precautions
■Precautions for Safe Use
Observe the following items to ensure the safe use of this product.
Environmental Precautions
•Store the H3AM within the specified ratings. If the H3AM has been
stored at temperatures –10°C or lower, let it stand for 3 hours or
longer at room temperature before turning ON the power supply.
•Use the H3AM within the specified ratings for operating
temperature and humidity.
•Do not operate the H3AM in locations subject to sudden or extreme
changes in temperature, or locations where high humidity may
result in condensation.
•Do not use the H3AM in locations subject to vibrations or shock.
Extended use in such locations may result in damage due to stress.
•Do not use the H3AM in locations subject to excessive dust,
corrosive gas, or direct sunlight.
•Install the H3AM well away from any sources of static electricity,
such as pipes transporting molding materials, powders, or liquids.
•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.
•Be sure to wire the terminals correctly.
•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.
•Internal elements may be destroyed if a voltage outside the rated
voltage is applied.
•Maintain voltage fluctuations in the power supply within the
specified range.
•Use a switch, relay, or other contact so that the rated power supply
voltage will be reached within 0.1 s. If the power supply voltage is
not reached quickly enough, the H3AM may malfunction or outputs
may be unstable.
■Precautions for Correct Use
Changing Switch Settings
Be sure to adjust the time unit selector and instantaneous or time-
limit output selector for R2 relay only before the Timer is turned ON,
otherwise the Timer may be damaged or malfunction.
Be sure to set the time only when Timer has stopped, otherwise the
Timer may malfunction.
Setting the Operating Time
Do not turn the time setting knob beyond the permissible range. If a
precise time setting is required, check the operation of the Timer in
trial operation before the Timer is put in actual operation.
Before using the H3AM-NSR, apply voltage between terminals 9 and
10 to reset the operation.
When changing the setting time of the H3AM-NSR to a longer time
value, be sure to apply voltage between terminals 9 and 10 during
the change.
Others
When mounting the Timer on a panel, evenly tighten the Timer to a
specified torque. If the Timer using waterproof packing is tightened to
a torque other than the specified value, required waterproof
properties will not be achieved.
If the Timer is mounted on a control panel, dismount the Timer from
the control panel or short-circuit the circuitry before carrying out a
voltage withstand test between the electric circuitry and non current-
carrying metal part of the machine, in order to prevent the internal
circuitry of the TImer from damage.
The internal elements may be damaged if a voltage other than the
rated supply voltage is applied.
■Precautions for EN61812-1
Conformance
The H3AM as a built-in timer conforms to EN61812-1 provided that
the following conditions are satisfied:
The output section of the H3AM is provided only with basic isolation.
The H3AM itself is designed according to the following:
•Overvoltage category III
•Pollution degree 2
On the above basis:
Operation parts on the front and bottom: Reinforced isolation
With clearance of 5.5 mm and creepage distance of 5.5 mm at 240
VAC
Output: Basic isolation
With clearance of 3.0 mm and creepage distance of 3.0 mm at 240
VAC
