Acknowledging errors
After errors have been noted, they can be deleted by acknowledging
the error messages. To do this, change to the display level "E" by
pressing the blue DISPLAY key repeatedly. When the DISPLAY key
is kept pressed for more than two seconds, all the errors on the "EA"
level are deleted. If the error state occurs again, the error code will
reappear on the display
Installation instructions
Installation location
The network nodes WT..662.. have only been designed for applica-
tions inside buildings. The type plate is on the inside of the device
cover.
Measures to avoid problems
Install the network node in a frost-free environment and not close to
high-voltage cables or electrical systems or on metallic or conduc-
tive surfaces.
Silicone must not be used as an adhesive for gluing the WT..662.. in
place. If silicone is used as an adhesive for tiles etc., you must wait
for at least 24 hours after the use of the silicone before the WT..662..
may be installed.
Siemens Smart Infrastructure
Mechanical attachment WT..662..
The WT..662.. must be fixed to the wall using two screws. For this
purpose, two holes with a diameter of 6 mm must be drilled 184 mm
apart. Screws and dowels are included in the scope of supply.
Electrical installation WTX662..
After the housing is opened, certain parts of this device
become accessible which can be under hazardous volt-
age.
During all work on the WTX662.. the device must be discon-
nected from the mains.
• The device is not equipped with a separator. Outside the device
there must be an easily accessible two-pole (L, N) disconnector
with a contact gap of at least 3 mm in the electrical system of
the building. The disconnector must be easily accessible to the
service employee.
• Only qualified electricians may carry out work on the device in
compliance with the electrical engineering regulations in accord-
ance with the type of use.
• The personnel must be familiar with all the sources of hazard and
maintenance measures in accordance with the regulations speci-
fied in these instructions.
Non-observance of these warnings can lead to physical inju-
ries and property damage.
• Insert the cable gland included into the through bore of the
housing.
• Tighten the counternut of the cable gland.
• Insert the cable.
• Connect the cable wires in accordance with the "mains power
connection" diagram.
• Fix the cap nut of the cable gland.

Installation RS232 WTX662..
Connect the cable of the RS232 connection to the RS232 interface
of the WTX662.. (13). Please note that data are received via the TX
connection and transmitted via the RX connection (see arrows on
the RS232 interface).
On the opposite side, the corresponding assignment is as follows
when a 9-pole D-Sub bushing is used, for example:
WTX662..
GND
RX
TX
The standard Baud rate is 9,600 Baud. If necessary, it can be
changed using the application ACT26.
