DIRECT CURRENT BILLING METER
3
Specifications
•
Time source to set product's time must be
provided by the customer. Product must be time
synchronized to operate.
•
Product's Ethernet interface mustn't be exposed
to a public network; network must be private and
secured.
•
To ensure proper operation, product's logbook
completion must be checked periodically; the
maximum number of entries is 40 000; product's
operation stops if logbook is full. The meter
•
must be install inside an enclosure IP51
(indoor) or IP54 (outdoor) according to EN
50470:2007.
Accuracy notices according to PTB type
examination certificate
•
The direct current meters may only be used
for billing purposes in business and official
traffic in a charging device and only for
measuring the energy supplied to the vehicle.
•
The connection line for voltage measurement
must be provided with the supplied ferrite so
that the measurement reliability is guaranteed
in the event of interference.
•
For the device types DCBM_N0D_4000_0000
and DCBM_N0D_4010_0000, for which the
compensation factor can be selected via the
Ethernet interface, either the interface must be
sealed or a calibrated remote station that can
be used with this measuring device must be
connected directly, secured by means of
seals, etc. . At the end of the transaction, this
remote station must compare or directly
overwrite the cable ID specified in the data
tuple signed by the meter with the cable ID
originally transferred to the DC meter. The
data record may only be used if the check is
positive
