5.1 Safety Cover
The safety cover is a plastic lid covering the programming keys and safety fuses. The lid can be removed if desired. In
order to avoid undesired modification of important settings, however, it is recommended that the lid be left on the System-
Manager. Intentionally, the lid is designed to be difficult to open. This is to prevent unwanted changes from being easily
made. The lid can be easily opened with following trick.
Hint: To open the cover, using your left-hand, stick your fingernail into the slot, move it along the slot and pull open the
cover.
When putting the lid on the case again, please make sure to put the turning joint into the case first and then into the
snap-in hole.
Using one of the option you can break the rated point on the left side.
