  • Page 3: Safety & Warnings

    Utilization category is AC-53a or AC-53b, Form 1. For further information, see Technical Specification Warnings Internal components and PCBs are at mains potential when the MIP-6 is connected to mains. This voltage is extremely dangerous and will cause death or severe injury if contacted.

  • Page 4: Technical Data

    The MIP-6 measures the insulation level when the motor is off line. Measurement is performed only when the upstream line contactor is open. A discrete (digital) input is used to inform the MIP-6 if it should measure the insulation resistance or not.

  • Page 5: Mip Selection

    (earth). For low voltage, up to 690V, the MIP-6 is directly connected to one of the motor phases. For MV, all three motor phases are connected to an external resistor and protection unit RU7/13. The output of the RU7/13 is connected to the MIP-6.

  • Page 6: Input Features

    The MIP-6 incorporates a rear RS485 serial link that uses a MODBUS RTU protocol (The protocol description is not included in this document) to provide high speed data acquisition to supervisory computers.

  • Page 7: Wiring Diagram

    (1) – The optional communication RS485 output is an isolated output. Use shielded twisted pair for RS485 communication. It is recommended to ground the shield near the MIP-6. (2) – The optional analog output is an isolated output. Use shielded twisted pair for analog output.

  • Page 8: Medium Voltage Wiring Diagram

    (6) – Use medium voltage leads to connect the RU7/13 to the M.V. motor. (7) –Use two ground connection to ground the RU7/13. (8) – Use low voltage leads from RU7/13 to MIP-6 unless these leads run near M.V. exposed equipment.

  • Page 9: Terminals Description

    Shield should be connected to Note: chassis ground externally, Connect 120 Ohm resistors near the MIP-6. between (+) and (-) at both sides Acceptable baud rates: 2400, of the line. 4800, 9600, 19200 and 38400 BPS.
  • Page 10 690V line to line. Connecting any live voltage to terminals 51 and/or 52 will cause immediate damage to the MIP-6 and can be dangerous!!! Terminals 51 and/or 52 must be connected to mains only through RU7 (up to 7200V) or RU13 (up to 13800V) unit.

  • Page 11: Control Keypad

    11 • Control Keypad CONTROL KEYPAD The control keypad is the link between the MIP-6 and the user. The MIP-6 control keypad features: (1) Three indication LEDs (On, Stand by/Active, Fault/Alarm) (2) Two lines of 16 alphanumeric characters each. (3) Six push-buttons (Page, Select/Reset, Select, Store, Up ( ) and down ( ) keys.

  • Page 12: Status Leds

    While underline mark does not show – Select key goes “forward”. • When MIP-6 is in latched trip or in alarm status the Reset key allows the user to reset the unit. The Reset key has to be pressed for 1 second in order to reset the MIP-6.

  • Page 13: Obtaining Default Parameters

    To obtain “default parameters” press Page+Store simultaneously. The LCD will display: DATA SAVED OK At this point (If “default parameters” were obtained) the MIP-6 exit test/maintenance mode. Obtaining Default Parameters erases all previously modified settings and CAUTION! requires the operator to program all parameters values again.

  • Page 14: Mode

    The backup capacitor retains data and keeps clock running for a few days. If the MIP-6 is not powered for a longer period, the clock has to be initialized. Initialization can be done manually as described above or through a serial link.

  • Page 15: Blinking Messages

    15 • Control Keypad Notes: 1. Pressing Store key while the LCD displays an "Actual Data" parameter, will store this parameter as default display. If no key is pressed for more than five minutes, this parameter will be constantly displayed. 2.
