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).
