1.1 User interfaces and menu structure

1.2 Introduction to the relay
1.2.1 Front panel
The front panel of the relay is shown in Figure 1, with the hinged covers at the top and
bottom of the relay shown open. Extra physical protection for the front panel can be provided
by an optional transparent front cover. With the cover in place read only access to the user
interface is possible. Removal of the cover does not compromise the environmental
withstand capability of the product, but allows access to the relay settings. When full access
to the relay keypad is required, for editing the settings, the transparent cover can be
unclipped and removed when the top and bottom covers are open. If the lower cover is
secured with a wire seal, this will need to be removed. Using the side flanges of the
transparent cover, pull the bottom edge away from the relay front panel until it is clear of the
seal tab. The cover can then be moved vertically down to release the two fixing lugs from
their recesses in the front panel.
