Connect the AC 230 V power supply line to the power pack of the WTX16… in the
following order: Remove the upper housing section of the WTX16… from the
base. For that purpose, remove the 2 cable connections (power supply (4) and M-
Bus (6)) between gateway and base. Then, use a suitable tool (screwdriver or
similar) to slightly open one of the two lateral fixing levers so that upper housing
section and base can be separated.
Then, the top section of the WT…16 is to be fitted using 2 dowels and screws
(spacing of dowels 184 mm with the WTX16...).
Connection of the AC 230 V power line to the power pack of the WTX16... is to be made as
follows:
A 2-core mains cable (L and N) is already preinstalled at the mounting site. The power pack
must be connected by qualified staff. The cores must be sheathed with the enclosed insulat-
ing sleeves to ensure compliance with safety class II. Then, the live (L) and neutral (N) con-
ductors must be connected to terminal “IN” of the power pack. 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 WT…16 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 Q AMR system can
automatically configure themselves to form a network.
Ensure that the local regulations for radio transmission installations and electrical installa-
tions are complied with.
