Operation (H3CR-H)
An interval of 3 s minimum is required to turn on the H3CR after the
H3CR is turned off. If the H3CR is turned on and off repeatedly with
an interval of shorter than 3 s, the internal parts of the H3CR may
deteriorate and the H3CR may malfunction.

After the forced reset function of the H3CR is activated, an interval
of 3 s minimum is required to activate the forced reset function
again. If the forced reset function is activated repeatedly with an in-
terval of shorterthan3s,the internalparts of theH3CR may deterio-
rate and the H3CR may malfunction.

If it is required that the output be turned on repeatedly with an inter-
val of shorter than 3 s, consider use of the H3CR-A in mode D (sig-
nal OFF-delay).
Power Supplies (H3CR-H)
An AC power supply can be connected to the power input terminals
without regarding polarity.ADCpowersupply mustbe connectedto
the power input terminals as designated according to the polarity of
the terminals.
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.
Connect the power supply voltage through a relay or switch in such
a way that the voltage reaches a fixed value at once or the Timer
may not be reset or a timer error could result.
For the power supply ofan input device, use an isolating transform-
er, of which the primary and secondary windings are mutually iso-
lated and the secondary winding is not grounded.

Circuit
Isolation transformer is required.
Rectifier circuit
The H3CR-H has a large inrush current; provide sufficient power
supply capacity. If the power supply capacity is too small, theremay
be delays in turning ON the output.

Note: 1. The above figures are all approximations and should be used for reference only.
2. The inrush current is given mainly for DC models for the required power supply design specifications. For the H3CR-H, the inrush
current is also given for 100/110/120-VAC and 200/220/240-VAC models because these models have higher inrush currents than
other series.
