If the drive is mounted in an exposed area, a protection level of IP55 or IP66 should be used. If the drive is in a cubicle, IP20 will usually be enough, but make sure there is no chance of dirt, dust or liquid getting into the drive.
EMC regulations should be followed; that usually means choosing a drive with a built-in EMC filter to limit interference into and out of the drive.
If you need high torque at low speed, or high performance at high power, choose an ‘industrial’ or constant torque drive such as the P2. For pump and fan applications which don’t need a high starting torque, a variable torque drive such as the Eco includes many useful features for these applications. A general purpose drive such as the E3 will generally do both jobs up to 22kW.
If you install the drive in a cubicle or machine, check the manual or application note AN-ODE-2-070, available on the Invertek website (invertekdrives.com) for information concerning cooling and EMC recommendations. There must be enough air, free from dust, dirt or liquids around the drive to cool it. Make sure the drive is properly earthed, and that the motor cables are screened or armoured.
Connect the wiring as described in the manual. Double check the motor and supply connections, and that you have the correct voltage unit. On units without built in controls, you’ll probably need a run stop switch (control terminals 1 and 2) and a potentiometer as a minimum to get started.
