Series Temperature Controller Instruction Sheet 

 Precaution 

Warning!  Please  comply  with  safety  precautions  in  the  manual.  Failure  to  do  so  may  cause  controller  or  peripheral  products 
malfunction, or even result in serious harm such as fire, electrical injury or other damages. 

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. 

This  controller  is  not  furnished  with  a  power  switch  or  fuse,  therefore  a  switch  or  circuit-breaker  should  be  provided  in  the
application system including this unit. The switch or circuit-breaker should be nearby and easily reached by operator, and must 
have the mark disconnecting means for this unit. 

1.

Always use recommended solder-less terminals: When integrated into a temperature control system, the maximum ambient
temperature is 50 degree C. Fork terminal with isolation (M3 screw, width is 5.8 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. When maintaining the controller, please turn off the power first and use a dry cloth to clean the surface. Do not open the enclosure or

touch the internal circuit to avoid circuit destruction or malfunction.

13. Do not use any sharp objects to press the operation buttons. It may result in button surface damage or even electrical injury when

accidentally access to internal circuit.

14. Measured current: When measuring current, use an external current transformer (CT).
15. When using this CT device, note that the current transformer must not be under an open circuit.
16. When using this CT device, make sure the powered bus on the secondary side of the current transformer has been locked and

secured to the device to prevent the bus falling during the use, which could damage the device.

17. When using the current transformer with the device, use the transformer that is compliant with the IEC-61010-2-032 standard to

ensure safety.

18. When measuring current, a current transformer must be used with the device.
19. Use copper conductors only.
