  • Page 14: Mounting And Installation

    EEM-MA200/EEM-MA250 Mounting and installation Avoid being in close proximity to systems that can generate electromagnetic interference. In addition, avoid mechanical vibrations with acceleration rates greater than 1g (9.81 m/s2) at frequencies below 60 Hz. Mounting The device is snapped onto a DIN rail in the control cabinet. The mounting position can be freely selected, but will be determined by the readability of the LCD.

    Maximum tightening torque for the relevant screws: 0.4 Nm. DANGER: Risk of electric shock If the device is disconnected, the secondary sides of the relevant current transformers must be short circuited. A URTK6 transformer disconnect terminal block (Order No. 3026272) can be used for this. 104415_en_00 PHOENIX CONTACT...

  • Page 16: Termination Resistor

    When selecting the current transformer, the secondary nominal current must be 5 A. The primary nominal current is determined by the current consumption of the load. Appropriate PACT current transformers can be found in the Phoenix Contact INTERFACE catalog. DANGER: Risk of electric shock Only install current transformers and corresponding measuring devices when the power supply is disconnected.
