Protection from abnormal vibration: for inverters with capacity of 22 kW or less
In an environment with large ambient vibrations, the inverter may be exposed to them, causing abnormal
vibrations on the multi-function keypad. If this happens, remove the terminal block cover and the front cover,
then secure the multi-function keypad to the inverter with the attached screw (Two). After that, reinstall those
covers.
For the procedures for removing the covers, refer to the FRENIC-Lift Instruction Manual
(INR-SI47-1038-E), Chapter 2, Section 2.3.1 "Removing and mounting the terminal block (TB) cover and
the front cover."
