Cautions in installation
The electricity box opening size of controller is 71mm×29mm, and should install electricity box of controller in place with good ventilation, oil-proofing and dust proof. The preference temperature of electricity box is below 55℃, relative humidity less than 85%RH and no condensation. It is necessary to avoid controller being installed too close to AC accessories: contactor, transformer, and so on; the controller must be kept away from strong electromagnetic field environment, for avoiding unnecessary interference and affecting the normal work.
