Mains voltage must be in the range from AC 100 to 240 V (50 / 60 Hz). There is no
protective earth (PE) connection. Then, cable strain relief must be provided by fitting
cable ties.
Once the top section of the WTX16 is fitted, the housing with the electronics can be
snapped on. Then, the power supply connector can be plugged into the electronics
section and the WTT16 switched to installation mode by pressing the MODE button
(red) for a few seconds. Then, additional network nodes or consumption meters of the
Siemeca™ AMR system can automatically configure themselves to form a network.
After the complete installation of the network the gateway must do a search run to find
all meters of the network(s). One can start a search run either by restarting the
WTX16… by disconnecting it shortly from the mains power (switch S) or by triggering it
with a command sent by the commissioning software ACT21 from a PC attached to the
network node.
Screw tight the GSM antenna prior to commissioning
Network nodes WTX16.GSM require a SIM card. For that purpose,
remove the upper section of the WTX16.GSM from the base. Remove
the 2 cable connections (power supply and M-Bus) between gateway
and base. Then, use a suitable tool (screwdriver or similar) to open
one of the two lateral fixing levers so that upper housing section and
base can be separated.
Insert the SIM card in the slot at the bottom of the gateway.
