In spite of expensive protection measures, exceptionally strong magnetic
fields can lead to the destruction of the micro-processor controlled time
switch.
We therefore recommend attention be given to the following
points before installation:
Use separate lead for the mains voltage supply.
Suppress inductive loads with suitable RC filters.
Do not mount product in direct proximity to sources of interference as
e. g. transformers, contactors, PCs and TV and communication
equipment.
After suffering intereference, we recommend, before re-setting, a RESET
with a new initial set up (chapter 5.3).
Strongly heat-generating products on the right side of the product shor-
ten the life of the battery.
Work on the European installation bus must only be carried out by quali-
fied electrical technicians.
National regulations and any valid safety conditions should be observed.
->
The time switch and the bus line must be connected in accordance
with applicable DIN – VDE guidelines and the ZVEI/ZVEH Handbook.
The time switch:
->
Must only be operated with the data from the product database
->
Must only be used in dry areas
->
The time switch is suitable for use in environmental conditions with
normal pollution
->
The time switch is suitable for mounting on the 35 mm top-nat rail
Unauthorised modifications to the equipment render the warranty invalid.

Busleitung
The time switch controls connected bus participants via a group address.
It transmits either 1, 2 or 8-bit telegrams, including the time.
With the time program and the corresponding application, the time can be
transmitted and received via the BUS.
Transmission of current switch-time or date telegrams is only possible in auto-
matic mode.
