  • Page 5 PDS51 Series Safety Precaution ■Arrival Inspection ◎If the controller is damaged or parts are missing, do not install or operate it. Otherwise it may result in equipment damage or personal injury. ■Installation ◎ When installing and moving, please hold the bottom of the product, not just the casing, to prevent injury or damage to the controller.
  • Page 6 PDS51 Series ■Running ◎ The controller can be powered on after the wiring is completed and the cover is installed. It is strictly forbidden to remove the cover when the power is on, otherwise it may cause electric shock. ◎The water pump must be installed before testing the steering of the water pump. The water pump should not be allowed to do dry run for a long time.
