Data safety information and Warning

If you have the annual maintenance work carried out by a Honeywell service technician,
any errors can be rectified immediately. Naturally, you will also receive detailed
documentation of the work. Then you only have to archive these documents.
In any case, the following always applies:
DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT
CAUTION
DISCONNECT POWER BEFORE OPENING
After several years of operation, additional maintenance and repair work may be required
due to wear and ageing. Examples of this include battery replacement (around 5 years)
and the replacement of blocked inlet filters. Furthermore, factory maintenance is
required if defects are identified during the annual maintenance work which cannot be
rectified or if the housing has suffered damage.
Depending on the nature of this work, it may require the housing to be opened or the
device to be completely dismantled or returned to the manufacturer.
The required work (with the exception of the complete replacement of the device) may
therefore only be carried out by Honeywell service staff or by personnel trained by
Honeywell.
For example, the housing can only be repaired by the manufacturer since the
dimensions of the explosion-protection gaps are not part of the public domain and are
only specified in the manufacturer's design documents. Please contact your TAC if you
require such services.
Devices and therefore also the enCal 3000 are used in modern infrastructures and
network control systems with the aim of transferring process information such as meter
readings, measurements and messages to a central billing or control point. A connection
of this type constitutes a significant security risk which must be given due consideration
when designing the network.
