A separate sealable screw secures the Terminal Cover.
A separate sealable screw secures the Comms Hub.
The Outline and Fixing Dimensions are shown in 34.5.

6.6. Unauthorised Physical Access (Tamper Detection)

If a Tamper Event is detected the meter can be configured to open the Main Contactor. In this event the contactor can only
be closed again by a Command from DCC.
Communications Hub Removal Detection
Pins are provided on the Comms Hub or in the ICHI Blanking Plate that allow the meter to electronically detect if the
Comms Hub is present or not.
The Removal of a Comms Hub event is stored in the Security Log with a Time and Date Stamp.
Magnetic Field Detection
The AS302P has a sensor which detects if a Strong Magnetic Field has been detected or removed.
The detection or removal of a Magnetic Field is logged in the Security Log with a Time and Date Stamp.
Detection Level of a Magnetic Field (three planes) is:
Range 25 to 60 Gauss (2.5 to 6.0 milli-Tesla).
When there is no power to the meter, only the first tamper event will be recorded:
Main Cover and Terminal Cover Removal Detection
The Main Cover and Terminal Cover are fitted with Tamper Switches to detect removal.
The Removal of a Cover Event is stored in the Security Log with a Time and Date Stamp.
7. TEST OUTPUT DEVICES & ANTI CREEP INDICATION
Test Output Devices
An Optical Test Output is provided (Normally indicates kWh, reprogrammable to show kvarh).
The indicator pulses for both Import and Export Energy.
The indicator is not modulated.
The Test Indicator Pulse Rates are set at manufacture to 4,000 pulses/kWh (kvarh).
The Pulse Duration is set at 5ms (default).
The Pulse Rate configured is shown on the Meter Nameplate.
Anti-creep
The Watt and var anti-creep thresholds are set at Manufacture.
The kWh (kvarh) Test Indicator is continuously illuminated when the Active Energy Anti-creep Lock is operating.
