WARNING:
•
Properly connect multiple pairs of sensors
•
Connecting multiple output signal switching devices (OSSD) safety outputs to one interface
module or otherwise parallel OSSD outputs can result in serious bodily injury or death, and is
prohibited.
•
Do not connect multiple pairs of sensors to a single device.
5.7 Mounting System Components
5.7.1 Mounting Hardware
After the mechanical layout considerations are addressed, mount the sensors and route the cables.
All brackets are ordered separately; no brackets are shipped with the sensors. The quantity of brackets ordered and the
placement of those brackets must ensure the unsupported distance (distance between brackets) is less than 900 mm (35.4
in).
