1 Safety Instructions
!
!!
!
Please read these instructions carefully before assembling, installing or commissioning
the EM260 to avoid any damage, dangers or problems.
Assembly and installation should be carried out by qualified personnel !
!
!!
!
The ‘AC’ version of the EM260 has a power supply of 90...260 V. Do not touch any live
parts as this is extremely dangerous !
Shut off the power supply before carrying out any installation work and before opening the
housing !
Switch the power back on only after all of the work has been completed and the housing
has been firmly closed!
Other notes:
 The PE connections in both the EM260 and the EK2x0 should be as short as possible
and have as wide a cross-section as possible.
 When assembling the front cover, ensure that the flat-strip cable for connecting the LEDs
integrated into the front transparent film is plugged into the 4x1 pin strip ST8!

4 Wiring of EM260´s communication interface
If an analogue modem, an ISDN adapter or an Ethernet adapter is mounted inside the EM260,
the corresponding cable is also mounted by Elster-Instromet exworks. The cable is connected to
the terminals a(Rx-), b(Rx+), a2(Tx-) and b2(Tx+).
When using a CL0 interface, a shielded cable with two leads (e.g. ID no. 04250467, 2 x 1,0 mm
2
)
must be connected on site by the customer in the following way:
EM260 terminal
Terminal in the C
L1 modem
a (Rx-) CL- / Rx-
b (Rx+) CL+ / Rx+
5 Settings of the serial interface in the EK220/260/280
If the EK2x0 is delivered together with the EM260, the EK2x0´s internal serial interface as well as
the communication module integrated in the EM260 are properly set by Elster-Instromet exworks.
If the EM260 is delivered separately for additional installation beside an EK2x0, the internal serial
interface of the EK2x0 must be set in accordance with the software version of the EK2x0 and with
the type of communication module integrated in the EM260.
 The serial interface of the EK2x0 must be parameterised before the EM260 is
connected to the EK2x0 and switched on.
For this purpose the parameter software “WinPADS200-EK“ or “enSuite” (only for EK280) can be
used:
- WinPADS200-EK: Menu “Data transfer”, item “Send parameter file…”
- enSuite: Item “Send parameter file”, then button “Open…”
Then you can select the parameter file (*.WPP) which fits to your application (communication
module, version of EK2x0).
Example:
EM260 with an analogue modem connected with an EK280 V2.0:
„EK280_2v2.. - EM260 & i-modul Analogmodem_a.WPP“
If there is no laptop with WinPADS or enSuite available on site, you can set the most important
values via the keypad of the EK2x0 (EK220/260: menu “Ser.IO”, EK280: menu “Terminal
Interface”).
The following values cannot be set via the keypad: SMS specific values, ISDN MSN, IP address
for Ethernet.
The following table contains the most important parameters which can be set via the interface
menu:
For the wiring, a shielded 8-wire cable
(Elster-Instromet ID no. 04250469) is
recommended. In the EM260 the cable
is assembled by Elster-Instromet
exworks. When connecting the EM260
to the EK2x0, please ensure the cable
is properly inserted into the EMV cable
fitting on the EK2x0.

According to the settings in the CL1 modem and the other devices installed in the current loop (CL).
3)
This setting (number of rings) is not used in mode 5. In mode 5 the communication module in the EM260
always picks up an incoming call after the first ring signal.
4)
Numbers in bold: Exworks settings performed by Elster-Instromet if the EK2x0 is delivered without any
modem.
6 Setting the parameters for the communication module
The parameters for the communication module (modem) in the EM260 are set ex-works for use
with an EK2x0.
If the parameters have to be modified on site, this can be carried out with the help of the
parameter software “WinPADS200-EK“: Menu „File transfer…“, item “Send parameter file…”.
Then you can select the parameter file (*.WPP) which fits to your application (communication
module, version of EK2x0).
Example: EM260/Analogue modem with EK260 V2.55
“EK260_2v5.. - EM260 & int. Analog-Modem (Insys)_b.WPP“
Before disconnecting, the button “Init modem“ should be pressed (“Interface – Modem
initialisation“). after it is disconnected, the EK2x0 sends the parameters to the communication
module. The parameters are also sent after switching on the power supply and after “M.INI=1” in
EK2x0´s menu “Ser.IO”.
The parameterisation of the communication module does not work with all EK2x0 versions and
also not with all types of communication modules. The following table shows the dependences
(“x“ means: Communication module can be parameterised by the EK2x0):

Parameterisation can be carried out only by Elster-Instromet exworks or by Elster-Instromet customer
service on site with the help of the software tool “ModemIni“ (ID no. 73017249).
2)
CL0 interface need not be parameterised
3)
The modem parameters, of course, can be set by “WinPADS200-EK“ („Interface – String for connected
modem“), but after carrying out the parameterisation (Button „Init modem“, „M.INI=1“ or switching on
power supply) they must be deleted again!!! Otherwise the communication module will not pick up any
further incoming call!!!

7 Replacement of communication modules
A faulty communication module can be substituted by another communication module of the
same type by the customer on site. It depends on the software version of the EK2x0 and on the
type of the communication module if the new module can be parameterised on site or if it must be
parameterised by Elster-Instromet exworks (refer to the table in chapter 6).
The replacement of a communication module by another communication module of a different
type (e.g. analogue modem replaced by ISDN adapter) can only be carried out by Elster-
Instromet exworks or by Elster-Instromet´s customer service.
8 Power supply
The voltage required for power supply is marked on the nameplate (90...260 VAC / 18...30 VDC).
