1-3 Storage
1. Must be placed in a dust-free, dry place.
2. Storage temperature: -10℃~+40℃.
3. Storage humidity: 0%~90%.
4. Vibration: <20Hz: 9.8m/s2 (1G) max; 20Hz~50Hz: 5.88m/s2 (0.6G) max.
5. Even if the humidity meets the specification requirements, if the temperature changes rapidly, condensation and freezing may occur, and storage in such places should be avoided.
6. Avoid storing in corrosive gas and liquid environment.
7. It is best to store it properly packaged on a shelf or table.
8. If it is opened and used for more than 3 months, the ambient temperature of the storage environment should not be higher than 30 ℃. This is because the characteristics of electrolytic capacitors are easily degraded when the ambient temperature is too high when they are stored without electricity. Do not leave it for more than a year without electricity.
2. Installation and wiring
2-1 Installation Environment Conditions
1. Ambient temperature: -10~+50℃ (14~104F).
2. Relative humidity: <90%, no frosting.
3. Installation height: <1000m;
4. Pressure: 86~106kPa.
5. Vibration: <20Hz: 9.8m/s2 ((1G)max; 20Hz~50Hz: 5.88m/s(0.6G)max.
2-2 Wiring Instructions
1. The power supply must be connected to the L and N terminals of the POWER of the controller. If the power supply is connected to other terminals by mistake, the controller will be damaged.
2. The 485 bus of the control layer is divided into A and B. The A line is connected to A, and the B line is connected to B; it is best to use a two-color 1mm2 twisted pair.
3. This controller uses the RS485 communication method. In order to improve the stability, it is recommended to connect the communication line by hand.
4. Terminals and wires to ensure high reliability of the connection.
5. For the selection of the wire diameter specification of the wiring, please implement the wiring in accordance with the electrical regulations. Tighten the screws of each terminal to prevent sparks from loosening due to vibration.
6. After completing the circuit wiring, please check the following points:
a) Are all wiring correct?
b) Is there any missing wiring?
c) Is there a short circuit between the connecting wires of each terminal or a short circuit to ground?
