Precautions
Refer to Safety Precautions for All Timers.
Do not touch any of the terminals while power is being supplied. Doing
so may result in electric shock. Be sure to mount the terminal cover
after wiring.
Do not use the Time Switch in locations subject to flammable or
explosive gases. Doing so may result in explosion.
Do not disassemble, repair, or modify the Time Switch. Doing so may
result in electric shock, fire, or malfunction.
Tighten terminal screws to the specified torque (approx. 0.98 N⋅m).
Loose screws may occasionally cause fires or malfunction. (Maximum
torque: 1.17 N⋅m)
Before changing times or other settings while power is being supplied,
either turn OFF the power on the load side or set the output ON/OFF
switch to OFF and confirm the safety of the system.
The life expectancy of the output relays depends on the switching
capacity and switching conditions. Consider the actual application
conditions and use the Time Switch within the rated load and
electrical service life. If using the Time Switch beyond its ratings is
unavoidable, use it together with an electromagnetic switch or
contactor as shown in the following diagram.
Using the Time Switch beyond its life expectancy may result in contact
deposition or burning.
Do not disassemble the Time Switch, deform the Time Switch by
applying pressure, heat the Time Switch to temperatures above
100°C, or incinerate the Time Switch. Doing any of these may cause
the built-in lithium battery to ignite or rupture.
■ Wiring
• Be sure to wire the terminals correctly.
• Do not connect more than two crimp terminals to each Time Switch
• Perform wiring using appropriate wires of the type specified in this
■ Power Supplies
• Make sure that the fluctuation of the supply voltage is within the

fire due to abnormal heat generation.

supply capacity, operation may not start. Be sure to use a power
supply with a sufficient capacity and a breaker.

■ Installation
• Mounting the Time Switches side-by-side may reduce the life
• When using heaters, be sure to use a thermal switch for the load
• When driving an inductive load (e.g., coil), a surge voltage is gener-
As a rough guide, the capacitor (C) and resistor (R) should have the
following specifications:
C: 0.5 to 1 µF for a switching current of 1 A
R: 0.5 to 1 Ω for a switching voltage of 1 V
Use a capacitor with a dielectric strength appropriate for the power
supply voltage. Use an AC-type capacitor with AC circuits. There
may be cases where, due to inconsistencies in the nature and char-
acteristics of the load, delays in restoring the load may cause prob-
lems. Be sure to confirm that correct operation is possible under the
actual operating conditions.

Doing so may result in the premature deterioration of internal com-
ponents (e.g., electrolytic capacitors).

magnetic relays), connect noise-absorbing elements (resistor and
capacitor) to both ends of the coil.
