If set indoor, it only needs to configure a trailer, drag it to indoor location specified. Please provide sizes and weights of each type of hydraulic module, convenient to hoist and make a hole in place.
  • Page 16 Hydraulic Module 50Hz MCAC-ATSM-2014-11 Make sure the linkage with the main unit device is normal, confirm the action of flow switch, confirm the operation status of pump, confirm the visual value on the hydraulic module dial is normal or not, and confirm whether the phase sequence protection, water-lacking protection, overload protection and other functions are normal.
  • Page 17 MCAC-ATSM-2014-11 Hydraulic Module 50Hz (1). Power supply of the unit must be connected (switching-on) strictly on the basis of electric requirements. Please don’t share power lines with other appliances. (2). Please ensure that the unit is reliably grounded, prevent leakage accidents when installing. (3).
  • Page 18 Hydraulic Module 50Hz MCAC-ATSM-2014-11 Attention! Frequently start-up would impact the lifespan of unit. Strongly recommend: When the units started up, don’t frequently start or stop the units. Don’t dump directly if it's out of necessary. 14.7 Commissioning (1). Check whether the unit is well earthed. (2).
