7.2 Terminal Cover Tamper Detection
The ES-10B meter has an internal micro switch that detects the opening of the terminal cover. It is
located at the centre of the terminals. The meter generates an alert, which will be sent via the HAN
to the energy supplier and logged internally, when the switch is released. This switch also serves
to enable access to the meter’s Engineering menu.
Note: To access the Engineering menu, you do not need to completely remove the
terminal cover. The recommended practice is to simply loosen the terminal cover until
the tamper switch releases.
