Safe 4 Shock Mounting Kit
Rockwell Automation offers a shock and vibration isolation kit for
vertically mounting the Safe 4. This kit is most effective in
protecting the internal optical and electronic components of the
Safe 4 light curtain. The best performance of the shock and
vibration isolation kit is attained when the kit is used in
conjunction with the Safe 4 vertical mounting brackets (445L-
AF6144).

Power Supply
The external voltage supply (+24V DC) must meet the
requirements of IEC 61496-1. In addition, the following
requirements have to be fulfilled:
• A short-term power failure of 20 ms must be bridged by the
power supply.
• The power supply has double insulation between the
primary and the secondary side.
• The power supply is protected against overload.
• The power supply corresponds to the guidelines of the EWG
(industrial environment).
• The power supply corresponds to the Low Voltage
Directives.
• The grounded conductor of the power supply device must
be connected to a grounded conductor PE.
• The maximum deviation of the voltage levels is 24V DC +/-
20%.
