CAUTION
Indicates information that,if not followed,could
result in relatively serious or minor injury,
property damage,or faulty operation.

Never disassemble, deform, subject to heat over
100˚C or dispose in fire. The product has a buit-in
lithium battery. Fire, Explosion and Burn Hazard.
The life expectancy of the output relay varies considerably
according to its usage. Use the output relay within its rated
load and electrical life expectancy. If using the Time Switch
beyond its ratings is unavoidable, use it together with an
electromagnetic switch or contactor in the way described
on page 32. If the output relay is used beyond its life
expectancy, its ontacts may become fused or there may
be a risk of fire.
Before changing times or other settings while power
is being supplied, either turn OFF the power on the
load side or set the Out ON/OFF switch to OFF and
confirm the safety of the system.
Tighten the terminal screws securely. The
recommended tightening torque is 8.67 in.lb.
(0.98 N·m)[10.4 in.lb. max (1.17 N·m max)].
Loose screws may result in fire or malfunction.
Never disassemble, repair or modify the product.
This may cause electric shock, fire or malfunction.
Do not use the product where flammable or
combustion gases are present. There may be a risk
of explosion.
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.

● Precautionary Information
CAUTION

-3-
Please comply strictly with the following instructions which are intended
to ensure safe operation of the controller.
(1) Application of voltages other than the rated voltage may seriously
damage the internal elements.
(2) Separate the Time Switch from any potential sources of noise, such
as high-voltage lines. When using inductive loads
(e.g., electromagnetic relays), connect noise-absorbing elements
(resistor and capacitor) to both ends of the coil.
(3) Do not install the Time Switch close to sources of excessive static
electricity (e.g.,forming compounds, powders, or fluid materials being
transported by pipe).
(4) Locations subject to temperatures or humidity outside the range
specified in the specifications.
(5) Mounting the Time Switches side-by-side may reduce the life
expectancies of internal components.
(6) Do not use the Time Switch in environments subject to shocks or
vibration beyond the ranges specified in this document.
(7) Do not use the Time Switch in dusty environments, in locations where
corrosive gases are present, or in locations subject to direct sunlight.
(8) Store at the specified temperature. If the Time Switch has been stored
at a temperature of less than –10℃, allow the Time Switch to stand at
room temperature for at least 3 hours before use.
(9) This product is not waterproof or oil-proof. Do not use it in locations
where water or oil may enter the product interior.
(10) To prevent damage to the exterior of the Time Switch, it must not be
exposed to organic solvents (e.g. Paint thinner or benzine), strong
alkalies, or strong acids.
(11) When using heaters, be sure to use a thermal switch for the load circuit.
(12) Take adequate protective measures for the power supply of the Time
Switch (such as providing a breaker and fuse).
Precautions for Safe Use

-4-
(1) Be sure to wire the terminals correctly.
(2) Perform wiring using appropriate wires of the type specified in this
document. Using a different type of wire may result in burn injury or
fire due to abnormal heat generation.
(3) Do not use the Time Switch in the following locations:
• ELocations where condensation may occur due to high humidity levels
• ELocations subject to extreme temperature variations
(4) Do not leave the Time Switch for long periods (i.e., one month or
longer) at a high temperature with output current in the ON state.
Doing so may result in the premature deterioration of internal
components (e.g., electrolytic capacitors).
(5) Always maintain the power supply voltage within specifications.
(6) Apply the full power supply voltage through the breaker, switch, and
relay contacts simultaneously. Gradually increasing the voltage may
result in malfunction.
(7) When the power is turned ON, an inrush current will flow for a short
time (approx. 2 A for 0.3 ms at 264 VAC). Depending on the power
supply capacity, operation may not start. Be sure to use a power supply
with a sufficient capacity and a breaker.
(8) None of the Time Switch components are user-replaceable, including
the battery.
