Installation
■ POWER SUPPLIES
An AC power supply can be connected to the power input
terminals without regarding polarity. A DC power supply must
be connected to 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.
■ INPUT AND OUTPUT PRECAUTIONS
An appropriate input is applied to the input signal terminals of
the timer when the input terminal C1 and the common terminal
A2 for the input signal are short-circuited.
WARNING: Do not connect an input terminal to any terminal
other than the common terminal. Do not apply a voltage across
input and common terminals or the internal circuits of the timer
may be damaged.
For the power supply of an input device, use an isolating
transformer, of which the primary and secondary windings are
mutually isolated and the secondary winding is not grounded.
Use a commercial power supply with a sine-wave frequency of
50 or 60 Hz to supply 100 or 200 VAC.
When connecting a relay or a transistor as an external signal
input device, pay attention to the following points to prevent
short-circuiting due to a sneak current to the transformerless
power supply. If a relay or transistor is connected to two or
more timers, the input terminals of these timers must be wired
properly so that they will not be different in phase or the
terminals will be short-circuited to one another as shown below.
* Power supply terminal A2 is a common terminal for the input
signal (S) to the timer. Never use terminal A1 as the common
terminal for this purpose, otherwise the internal circuit of the
timer may be damaged.
** Do not connect a relay or any other load between these two
points, otherwise the internal circuit of the timer may be
damaged due to the high-tension voltage applied to the input
terminals.
■ ENVIRONMENT
When using the timer in an area with excess electrical noise,
separate the timer, wiring and the equipment which generates
the input signals as far as possible from the noise sources. It is
also recommended to shield the input signal wiring to prevent
electrical interference.
Organic solvents (such as paint thinner), as well as very acidic
or basic solutions can damage the outer casing of the timer.

Be sure to turn power OFF before changing the time range.
Otherwise the timer will malfunction. Use a Phillips screwdriver
to select the time unit (seconds, minutes, hours or 10 hours)
and the time scale range two upper turn pots. Set the time
using the large central knob. On H3DR-A and H3DR-P timers,
a fine-tuning adjustment helps match the timing exactly to the
application.
