Protection against environmental effects
Lasting and correct safety function requires that the system must be protected
against foreign bodies such as swarf, sand, blasting shot, etc., which can become
lodged in the locking and handle modules. For this purpose a suitable installation
position should be selected.
Cover device during painting work!
Electrical connection
Warning!
Mounting must be performed only by authorized personnel.
Caution!
Risk of damage to equipment or malfunctions as a result of incorrect connection.
ÌAll the electrical connections must either be isolated from the mains supply
by a safety transformer according EN IEC 61558-2-6 with limited output volt-
age in the event of a fault, or by other equivalent isolation measures.
ÌFor use and operation as per the requirements, a power supply with the
feature "for use in class 2 circuits" must be used. The same requirement ap-
plies to the safety outputs.
Alternative solutions must comply with the following requirements:
a) Electrically isolated power supply unit with a max. open-circuit voltage of 30
V/DC and a limited current of max. 8 A.
b) Electrically isolated power supply unit in combination with fuse as per UL248.
This fuse should be designed for max. 3.3 A and should be integrated into
the 30 V/DC voltage section.
ÌIn order to avoid EMC interference, the physical environmental and operating
conditions at the installation site of the device must comply with the require-
ments according to the standard DIN EN 60204-1:2006, section 4.4.2/
EMC).
Important!
ÌThe supply for further subscribers on the bus may be forwarded via the Eu-
chner MGB system. The entire supply current through the MGB must not be
higher than specified in the section Technical data.
ÌThe function earth must be connected. An M6 threaded bore is available
on the mounting plate for this purpose.
ÌIf the device does not appear to function when operating voltage is applied
(e.g. UB LED does not illuminate), the safety switch must be returned un-
opened to the manufacturer.
ÌTighten screw for the cover for the mechanical release to 0.5 Nm.
Connections on bus module
The bus module includes the PROFINET connections (X3 and X4) and the power
supply connections (X1 and X2). Depending on the version, connection is made via
push-pull plugs according to IEC 61076-3-117, variant 14 or 7/8"-plugs according
to ANSI/B93.55M-1981 and M12 plugs (d-coded) according to IEC 61076-2-101.
The bus module includes a PPOFINET RT switch for Ethernet connection.
