Input terminals will accept wire sizes from 24 AWG to 10 AWG. This port consists of 4 optically
isolated discrete input pairs. To make any input active, apply a wetting voltage across the inputs
within the range of 10 V TO 32 V. Each input will draw up to 18 mA at 32 V and down to 4 mA at
10 V. The wetting voltage can be sourced by an external isolated or non-isolated supply. For the
case of an external isolated supply, its ground would not be tied to the ground of the module. A
suggested connection diagram is given in Figure 7.

4 Power is applied to the module by a cable that enters the enclosure through the AC line power cable
gland and connects to the AC line surge suppressor. Line power connects to the L1 terminal of the
surge module. Line 2 or neutral connects to the L2 terminal of the surge module. Ground connects to
the GND terminal of the surge module.
5 Insert the DC fuse into the fuse holder.
6 When you are ready to activate the module, close the AC line breaker.
7 Contact your service provider to provision/activate this device on the cellular network. The cellular
modem is shipped with most of the parameters set for proper operation. For more information on
modem configuration and troubleshooting, contact your Elster representative.
8 After completing these steps, verify proper operation. See “Verifying proper operation” on page 8 for
more information.
