• Continue the necessary wiring of the MCB 112 VLT PTC Thermistor Card. See
Connection Schematic
in the previous chapter and in the chapter
Application Examples
.
• Afterwards, remove the gaps for slot "B" from the deeper frame supplied, and reinsert the frame, terminal cover, and the LCP control unit.
• Close the device with the cover or with the enclosure cover in order to restore the enclosure to its initial condition.
• Restore the power supply to the frequency converter.
• Configure new additional functions in the corresponding parameters.
Warning! Depending on the settings in par 5-19, the motor may start after the power supply voltage is restored!
Warning! The operator or the electrical installer is responsible for proper earthing and adherence to all applicable national and local
safety regulations!
4.1.3 Installation of a Category 0 Stop
To carry out an installation of a Category 0 Stop (EN 60204-1) in conformity with Safety Category 3, follow these instructions:
- The bridge (jumper) between Terminal 37 and 24 V DC must be removed. Cutting or breaking the jumper is not sufficient. Remove it entirely
to avoid short-circuiting. See jumper on the illustration below.
Illustration 4.3: Bridge jumper between terminal 37 and 24 VDC
- Connect terminal 37 to terminal X44/12 of the MCB 112 VLT PTC Thermistor Card with a regular cable. Only then can the frequency converter
reliably be shut down in case of malfunction. Please see the VLT AutomationDrive Guide FC 300 for a Safe Stop Commissioning Test.
- The lines for safety output 37 and logic must be laid separately. Warning: Maintain sufficient distance from the supply lines for the PTC resistors!
- The output on terminal X44/12 of the MCB 112 VLT PTC Thermistor Card must always be wired into the chain of the Safe Stop input on terminal
37 in order to ensure shutdown of power in case of malfunction. The MCB 112 VLT PTC Thermistor Card must always be the first device in such
a chain!
- Terminal X44/10 of the MCB 112 VLT PTC Thermistor Card must be connected to a digital input of the drive, which enables the drive to determine
whether safe stop was enabled by the MCB 112 VLT PTC Thermistor Card.
For further information please refer to the chapter Application Examples placed in a later section.
