1. When one input signal is simultane-
ously applied to more than one timer, be
sure to avoid the wiring shown in Fig. A.
Otherwise, the short-circuit current will
flow and cause damage. Be sure to align
the polarity of the power supply as
shown in Fig. B.

2. External surge protection may be
required if the following values are
exceeded. Otherwise, the internal circuit

3. For connecting and disconnecting
operating voltage to the timer, a circuit
should be used to prevent the flow of
leakage current. For example, a circuit
for contact protection as shown in Fig. C
will permit leakage current to flow
through R and C, causing erroneous
operation of the timer. Instead, the circuit
shown in Fig. D should be used.
of the timer, long continuous current flow
through the timer, causing generation of
heat internally should be avoided
because of the degradation it can cause.
For such long continuous operation, the
circuit shown below should be used.
