(3) Mounting direction
Mount the inverter vertically to the mounting surface and fix it securely with four screws or bolts so
that the logo "FRENIC-Multi" can be seen from the front.
Do not mount the inverter upside down or horizontally. Doing so will reduce the heat
dissipation efficiency of the inverter and cause the overheat protection function to operate,
so the inverter will not run.
(4) Solving abnormal vibration after installation
If any vibration in the surroundings reaches the inverter and causes abnormal vibration to the cooling
fans or the keypad, fix them firmly using the fixing screws provided as accessories.
