3.6 Removal and mounting of operating panel and cover

3.6.1 Removal and mounting of operating panel (keypad)

The operating panel of EM11 series Frequency inverter is a plug type, If you need to take it off when use or
maintenance, please make sure the gentle actions, or it is easy to damage the plug type connection terminals
on operating panel.
The removal and mounting of operating panel (keypad) is showed as Diagram3-3 and Diagram3-4:

Diagram 3-3 Removal of operating panel (keypad) Diagram 3-4 Mounting of operating panel (keypad)

3.6.2 Removal and Mounting of Frequency Inverter

The EM11 series frequency inverter above 7.5kw (380V) uses plastic case. The removal and mounting of
upper cover refers Diagram3-5. Please use tool to push the hooks on both side of lower cover.
