Please comply strictly with the following instructions which are intended
to ensure safe operation of the controller.
Precautions for Safe Use
(1)Install the Time Switch only by qualified electrical workers.
(2)Store the Time Switch within the specified ratings. If the Time Switch
has been stored at temperatures -10˚C or lower, let it stand for 3 hours
or longer at room temperature before turning ON the power supply.
(3)Mounting the Time Switch side-by-side may reduce the life
expectancies of internal components.
(4)Use the Time Switch within the specified ratings for operating
temperature and humidity.
(5)Do not operate the Time Switch in any of the following locations.
• Locations subject to sudden or extreme changes in temperature.
• Locations where high humidity may result in condensation.
(6)The Time Switch is not waterproof or oil resistant. Do not use it in
locations subject to water or oil.
(7)Do not use the Time Switch in locations subject to excessive dust,
corrosive gas, or direct sunlight.
(8)Install the Time Switch well away from any sources of excessive
static electricity, such as pipes transporting molding materials,
powders, or liquids.
(9)Maintain voltage fluctuations in the power supply within the
specified range.
(10)Internal elements may be destroyed if a voltage outside the rated
voltage is applied.
(11)Be sure to wire the terminals correctly.
(12)
Separate the Time Switch, the devices that generate input signals, input
signal wires from any potential sources of noise, such as high-voltage lines.
(13)Do not connect more than two crimp terminals to each Time Switch terminal.
(14)Up to two wires of the same size and type can be inserted into a
single terminals.
(15)Use the specified wires for wiring.
Applicable wire: AWG 22 to AWG 14 (equal to a cross-sectional
area of 0.326 to 2.081 mm
2
)
Solid wire or twisted wire
Copper
(16)Install a switch or circuit breaker that allows the operator to immediately
turn OFF the power, and label it to clearly indicates its function.
