Electrical Installation
Connections
The connection of a GuardShield Micro 400 to a machine
controller must occur using an MSR41 or MSR42 Series safety
controller module. Only prefabricated cable (445L-AC8xxx)
provided by Rockwell Automation may be used between the light
curtain and controller (Table 5).
The Micro 400 requires two patchcords, one for the transmitter
and one for the receiver. The M12 8-pin connector is used for
connecting to the light curtain, while the RJ45 connector is
plugged to the controller. M12 to M12 patchcords are used for
extending the cable, especially between cascades of the Micro
400 light curtain.
The connection cables are offered with color coded rings
attached to each cable. Remove one color ring from the cable as
necessary. The following color code is defined:
White – Transmitter (Tx)
Blue – Receiver (Rx)
Table 6: Available cable types
Figure 12: RJ45 connector/M12 8-pin connector male [shielded cable], connection cable from
MSR41 or MSR42 control unit to the light curtain
Figure 13: M12 connector (male)/M12 8-pin connector (female) [shielded cable], extension
connection cable or to use between light curtain cascades.
Power supply, inputs, safety outputs and status outputs are
connected to the terminal block of the MSR41, MSR42 controller
or a MSR45E (see wiring diagrams, figures 14 and 15 on page 15).
The interfacing of the light curtain with the machine control has
to be control reliable, i.e. a correct interface with a safety PLC or
safety relays with positive guided relay contacts.

ATTENTION
The safety devices and the interconnection to
the machinery have to comply with the basic
safety requirements as mentioned in the
current regulations and standards.
Direct interfacing of a safety light curtain to
machine control that does not meet the
necessary safety integrity level, i.e., use of
general purpose PLCs or general purpose
relays may result in injury to personnel.
