Safety Precautions for All H3CR Models
Note: The undermentioned is common for all H3CR models.
■ Precautions for Safe Use
Do not use the Timer in the following locations.
• Locations with radical temperature changes.
• Locations with high humidity that may result in condensation.
• Locations with excessive vibration or shock.
• Locations with corrosive gas or dust.
• Locations where the Timer is exposed to sprayed water, oil, or
Organic solvents (such as paint thinner) as well as strong acid or
alkali solutions will damage the outer casing of the Timer.
If the Timer is used in an area with excessive electronic noise, be
sure to separate the Timer, wires, and input device as far as possible
from the noise sources. Furthermore, it is recommended that the
input signal wiring be shielded to prevent electronic interference.
Using a surge absorber is recommended if surge voltages occur.
Pay the utmost attention not to make mistakes in polarity when wiring
the Timer.
The H3CR Series uses a transformerless power supply. Do not touch
the input terminals while the supply voltage is applied, otherwise an
electric shock may be received.
■ Precautions for Correct Use
Changing the Setting
Do not change the time unit, time range, or operation mode while the
Timer is in operation, otherwise the Timer may malfunction.
The time unit and time range can be set with the respective selectors
turned clockwise or counterclockwise.
The selectors are of notched so that they will snap when they are
properly set. Do not set the selectors midway between notches,
otherwise the Timer may break or malfunction.
Do not use H3CR-A models (except for H3CR-A@S) in flicker mode,
or H3CR-F models at the lowest selector setting. Doing so may result
in damage to contacts.
Power Supplies
A DC power supply can be connected if its ripple factor is 20% or
less and the mean voltage is within the rated operating voltage range
of the Timer.
An AC power supply can be connected to the power input terminals
without regard to polarity. A DC power supply must be connected to
the power input terminals as designated according to the polarity of
the terminals.
Make sure that the voltage is applied within the specified range,
otherwise the internal elements of the Timer may be damaged.
Connect the power supply voltage through a relay or switch in such a
way that the voltage reaches a fixed value at once, otherwise the
Timer may not be reset or a timer error may result.
Be aware that the operating voltage will rise by 5% if the rated
voltage is applied to the Timer continuously while the ambient
temperature is close to the maximum permissible ambient
temperature.
The power supply circuit of any H3CR-A model (except for H3CR-
A@S), H3CR-F 100-to-240-VAC model, and H3CR-G model is a
switching circuit. If the power line connected to the power supply
circuit has a transformer with high inductance, a counter-
electromotive voltage will be induced by the inductance. To suppress
the voltage, apply a CR filter to the power supply line.

ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
In the interest of product improvement, specifications are subject to change without notice.
Precautions for EN61812-1
Conformance
The H3CR Series as a built-in timer conforms to EN61812-1
provided that the following conditions are satisfied.
Make sure that no voltage is applied to any terminals before
dismounting the Timer from the Socket.
The output section of the H3CR is provided only with basic isolation.
The H3CR itself is designed under the following conditions:
• Overvoltage category III
• Pollution degree 2
• Isolation
Note: The 11-pin model ensures basic isolation by itself and also
Connect the two output contacts different in polarity to the loads so
that they will be the same in potential.
Others
If the Timer is mounted to a control board, dismount the Timer from
the control board or short-circuit the control board circuitry before
carrying out a voltage withstand test between the electric circuitry
and non-charged metal part of the Timer. This protects the internal
circuitry of the Timer from damage.
