Diving mixerMatching stainless steelField Control Box
The on-site control box for the supplied equipment should be technologicallyFrontierProven safe and reliable in actual operation, meeting all design specifications and conforming to general electrical technical requirements.
Each set of submersible mixer comes with a local control box.


Field control box requirements are as follows:
(1) Equipped with push buttons and signal lights; all control boxes have signal lights统一 colored red for stop, green for operation, yellow for fault, and blue for power indication.
(2) Order a matching converter for motor protection with the equipment.
(3) The start/stop button should have two pairs of contacts, and the emergency stop button (with a mushroom head) should remain engaged when pressed.
(4) Terminals use wire terminals.
(5) With cable connector.
(6) Protection Class: IP65.
(7) Reserve PLC interfaces; each equipment requires control from both the local control cabinet and the central control room.
(8) A 3P-32A circuit breaker must be left within the on-site control line and properly wired for the owner's future maintenance of the temporary power connection.
(9) The control box should have ventilation louvers on both sides and a cooling fan installed at the bottom.
