 Precaution
DANGER! Caution! Electric Shock! Do not touch the AC terminals while the power is supplied to the controller to prevent electric
shock. Make sure power is disconnected while checking the unit inside.
This controller is an open-type temperature controller. Be sure to evaluate any dangerous application in which a serious human
injury or serious property damage may occur.
1. Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, width is 7.2 mm). Make sure all wires are
connected to the correct polarity of terminals.
2. Do not allow dust or foreign objects to fall inside the controller to prevent it from malfunctioning. Never modify or disassemble the
controller. Do not connect anything to the "No used" terminals.
3. To prevent interference, keep away from high voltage and high frequency when installing. Do not install and/or use the controller in
places subject to:
(a) Dust or corrosive gases and liquid; (b) High humidity and high radiation; (c) Vibration and shock;
4. Power must be off when wiring and replacing a temperature sensor.
5. Be sure to use compensating wires that match the thermocouple types when extending or connecting the thermocouple wires.
6. Please use wires with resistance when extending or connecting a platinum resistance thermometer (RTD).
7. Please keep the wire as short as possible when wiring a platinum resistance thermometer (RTD) to the controller and please route
power wires as far as possible from load wires to prevent interference and induced noise.
8. This controller is an open-type unit and must be placed in an enclosure away from high temperature, humidity, dripping water,
corrosive materials, airborne dust, and electric shock or vibration.
9. Make sure power cables and signals from instruments are all installed properly before energizing the controller, otherwise serious
damage may occur.
10. Do not touch the terminals in the controller or try to repair the controller when power is on, in order to prevent electric shock.
11. Wait at least one minute after power is disconnected to allow capacitors to discharge, and please do not touch any internal circuit
within this period.
12. Do not use acid or alkaline liquids for cleaning. Please use a soft, dry cloth to clean the controller.
