Safety Relays
Operating Instructions
Read and understand these instructions before installing,
operating, or maintaining the equipment.
DANGER
!
Hazardous voltage.
Will cause death or serious injury.
Disconnect power before working on equipment.
CAUTION
Reliable functioning of the equipment is only ensured with
certified components.
The devices must be installed in switchgear cabinets with an adequate
degree of protection which takes the ambient conditions into account.
Important note
The products described here were developed to assume safety-related functions
within a system or machine. A complete safety-related system usually includes
sensors, evaluation units, signaling devices and concepts for ensuring safe
switch-off. The manufacturer of the system or machine is responsible for ensur-
ing the correct overall functionality. Siemens AG, its branch offices and associ-
ated companies (hereinafter referred to as
properties of a system or machine not designed by Siemens.
Siemens can also not assume liability for recommendations given or implied by
the following description. No new guarantee / warranty or liability claims in
excess of the general terms and conditions of Siemens can be deduced from the
following description.
Areas of application
The 3TK2826 safety relay can be used in EMERGENCY STOP mechanisms
according to EN 418 and in safety circuits according to EN 60 204-1 (11.98), e. g.
with movable guards and protective doors or with contact-free protection devices
according to IEC 61496-1 (06.98).
Depending on the outer wiring category 4 according to DIN EN 954-1, SIL3
according to IEC 61 508 or PL"e" according to EN 13849 must be achieved.
3TK2826-.BB40 only
Use a power supply unit that complies with
IEC 60536 safety class III (SELV or PELV)!
