This section describes the potential sources of danger, and the relevant safety
regulations applicable for the use of the Siemens Building Technologies NK8000
products.
Please read the following work instructions as well as the previous section "About
this document" thoroughly before beginning any work.
Danger potential to individuals
NK822x units are powered with low voltage DC. While there are no specific safety
regulations that apply to these devices, modifications made to safety/security sys-
tems in general may present a risk to the safety of the individual performing those
modifications, as well as to the equipment itself.
If used, the NE8001 cabinet is powered with AC voltage and the required power
cable should be installed following scrupulously the instructions given in this man-
ual.
1.1 Country-specific standards
Siemens Building Technologies products are developed and produced in compli-
ance with the relevant international and European safety standards. This document
provides warnings and recommendations specific to NK8000 products. Any addi-
tional country-specific or local safety standards and/or regulations that apply con-
cerning project planning, installation, operation, and device disposal must also be
taken into account.
As for any electrical equipment, proper grounding is critical to the safe operation
as it provides a protection against electrical shocks. Before starting any activity,
be sure that the electrical installation complies with relevant regulations and con-
forms to local safety standards.
1.2 Assembly and installation
The NK8000 units and NE8000 cabinets should always be installed in a clean and
stable environment; see the specific requirements given in the technical data sec-
tion on p. 57.
In particular, keep units and cabinets away from the following:
High levels of dust

Also, abide by the safety regulations of the connected devices.
1.3 Commissioning and testing
Activate security-, fire- and third party systems or devices only in the presence
of the person responsible.
Inform people before the testing of alarm devices - consider the possibility of
panic reactions.
Inform the alarm and fault receiving stations connected to the system before
carrying out tests.
