(1) Use and store the Digital Controller within the specified ambient temperature and humidity ranges.
If necessary, cool the Digital Controller.
(2) Do not prevent heat dissipation by obstructing the periphery of the Digital Controller. Do not block
the vents on the Digital Controller unit.
(3) The supplied power voltage and load must be within the rated and specified ranges.
(4) Be sure to confirm the name and polarity for each terminal before wiring the terminal block.
(5) Do not connect anything to unused terminals.
(6) Use the specified size of crimp terminals (M3, width: 5.8 mm max.) to wire the terminal block.
When connecting bare wires, use copper stranded or solid wires, and use AWG22 to AWG14 for
the power supply terminals and AWG28 to AWG16 for other terminals.
(Length of exposed wire: 6 to 8 mm)
(7) Ensure that the rated voltage is attained within 2 seconds after turning on the power.
(8) If you need to draw out the Digital Controller, turn off the power first. Never touch the terminals or
the electronic components, or subject them to physical shock. When inserting the Digital Controller,
do not allow the electronic components to contact the case.
(9) Do not remove the inner circuit board.
(10) The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.
(11) Allow a warm-up time of at least 30 minutes.
(12) Allow as much space as possible between the product and devices that generate a powerful high-
frequency or surge. Separate the high-voltage or large-current power lines from other lines, and
avoid parallel or common wiring with the power lines when you are wiring to the terminals.
(13) Install a switch or circuit breaker that allows the operator to immediately turn off the power, and
label suitably.
(14) The product is designed for indoor use only. Do not use the product outdoors or in any of the
following locations.
Locations where dust or corrosive gas is present (in particular, sulfur or ammonia gases)
Locations where condensation or ice may form
Locations directly exposed to sunlight
Locations subject to strong shocks or vibration
Locations where water or oil may splatter on the Digital Controller
Locations directly exposed to radiant heat from heating equipment
Locations subject to sudden or extreme changes of temperature
(15) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
