9 Battery Change
Only approved batteries are allowed to be used:
Manufacturer Type Part number Voltage Electric current
SAFT 2.M20SV 0020400007 6 V 12,6 Ah
- Remove the cover (unlock the black clamps by pressing them a bit into the housing).
- Exchange the battery. Press the cover into the case till the black clamps snap into the cover.
- Apply the new adhesive seal enclosed. The added bar code label can be used for the purpose of
documentation.
- The old batteries must be disposed of according to relevant environmental regulations.
10 Operating Conditions
Battery (6 V) Mains (5 V)
Possible interfaces in addition to
wireless M-Bus
GSM/GPRS GSM/GPRS
Ambient temperature -20 °C to 60 °C -20 °C to 30 °C
Protection class IP65 (GSM/GPRS)
Lifetime estimated, two batteries 5 years (limited read-outs of wireless M-Bus telegrams;
limited GSM/GPRS data transmissions)
11 Time
The Gateway has an integrated real-time-clock, to ensure timing functions. The clock must be set during the first
configuration. Automatic changeover between standard and summer time is not supported. The time will be
synchronized with the stored NTP server every time an upload of the data starts.
In the event of power loss and resumption, the gateway time is automatically synchronized with the NTP.
Parameter Possible settings
Time zone (GMT) -11 to +12
12 Interfaces and Options
General information about wireless M-Bus and GSM/GPRS radio transmission:
Installation of radio components between or behind heating pipes, or the presence of other bulky metallic obstacles
directly over or in front of the housing must be avoided.
The transmission quality (range, telegram processing) of radio components can be negatively influenced by
instruments or equipment with electromagnetic emissions, such as telephones (particularly LTE mobile radio
standard), Wi-Fi routers, baby monitors, remote controls, electric motors, etc.
In addition, the construction of the building has a strong influence on the transmission range and coverage.
Furthermore, when using installation boxes (substations) they must be equipped with non-metallic covers or doors.
The mentioned factory settings refer to a Gateway with two batteries.
12.1 Radio interface wireless M-Bus EN 13757-3, -4
Interface for reception of meter data.
12.1.1 Technical data wireless M-Bus
Frequency 868 MHz
Protocol wireless M-Bus based on EN 13757-3, -4
Selectable modes T1; C1; S1
Telegrams - short telegram for AMR (in conformity to OMS generation 2, 3, 4)
- long telegram with monthly values (in conformity to Engelmann specification)
Encryption AES: Advanced Encryption Standard; key length: 128 bits
In battery power mode the data from up to 1000 devices (1500 in external power supply mode) can be processed.
To reduce the number of collectable devices, it is possible to use whitelist for desired and blacklist for not-desired
devices. Each list supports wildcards and up to 1000 entries. The whitelist can also be restricted by the blacklist.
