A communication unit is installed when the meter is used in a system
where remote meter reading is employed. Remote meter reading requires
communication between the meter and the central station , which the
communication unit provides via a serial interface or modem.
Remote meter reading, time synchronisation with the central station time,
meter check to ensure the meter is functioning correctly, and parameter
setting can be performed using the communication unit.
If a communication unit is not required, a dummy is inserted.
For f6, the terminal cover protects the meter terminal connecters. The
terminal cover is secured with two utility's seals to prevent unauthorised
access, both for safety and antitampering reasons.
