2. Control cabinet installation opening size: 177mm * 128mm;
3. Controller installation: When installing, open a hole in the front panel of the control cabinet (opening size: 177mm * 128mm), pull out the controller terminal block and inlay it on the front panel, fix it with a random clip, and plug in the terminal block And then wiring.
Third, matters needing attention
1. The multi-pump starting control contactors should be interlocked when wiring. The contactors for variable frequency power frequency switching are recommended to be mechanically interlocked contactors.
2. When the contactor contact current driven by the controller exceeds 5A, an intermediate relay or a small contactor should be added between the controller and the contactor to drive, otherwise the controller will be damaged when the high-power contactor is activated.
3. As the product is continuously upgraded and improved during use, if individual parameters or descriptions in this user manual are not consistent with the actual product, without prior notice, the actual product is the main product or the dealer or manufacturer is consulted.
