Block diagram
Wiring diagram
(1) The instrument wiring adopts Pluggable connecting terminal ;
(2) The soft copper cross-sectional area of the input side wire must be greater than 0.5mm2, and the output side must be greater than 1mm2;
(3) The exposed length of the wire is about 8mm, which is locked by M3 screws;
(4) The output contacts must provide enough fuse protection connections;
(5) Copper conductor must withstand an ambient temperature of at least 75 ℃;
(6) Terminal screws can cause misoperation, heating, etc. Therefore, please tighten it according to the specified torque. Terminal screw tightening torque 0.5Nm.
Installation
Safety relays should be installed in control cabinets with at least IP54 protection level.Meanwhile, the installation and use should comply with the relevant provisions of GB 5226.1-2019 "Mechanical and Electrical Safety - Mechanical and Electrical Equipment - Part 1: General Technical Conditions".
The PH6401-3A1B series safety relays are all installed with DIN35mm guide rails. Installation steps are as follows
(1) Clamp the upper end of the instrument onto the guide rail;
(2) Push the lower end of the instrument into the guide rail.
Dismantling
Insert a screwdriver (blade width ≤ 6mm) into the metal latch at the lower end of the instrument panel;
Push the screwdriver upwards and pry the metal latch downwards;
Pull the instrument panel up and out of the guide rail.
Attention
Please verify whether the product packaging, product label model, and specifications are consistent with the purchase contract;
Before installing and using safety relays, carefully read this manual;
If you have any questions, please contact the Beijing Pinghe Technical Support Hotline at 400 711 6763;
The safety relay should be installed in a control cabinet with at least IP54 protection level;
24V DC power supply for instruments, and the use of 220V AC power supply is strictly prohibited;
Maintenance
(1) Please regularly check whether the safety function of the safety relay is in good condition, and whether there are signs that the circuit or the original is tampered with or bypassed;
(2) Please follow the relevant safety regulations and operate according to the instructions in this instruction manual, otherwise it may lead to fatal accidents or loss of personnel and property;
(3) The products have undergone strict inspection and quality control before leaving the factory. If you find that the products are not working properly and suspect that the internal module is faulty, please contact the nearest agent or directly contact the technical support hotline 400 711 6763.
(4) Within six years from the date of delivery, all product quality problems during normal use shall be repaired by Pinghe free of charge.
