Safe 2 Shock Mounting Kit
Rockwell Automation offers a shock and vibration isolation kit for
vertically mounting the Safe 2. This kit is most effective in protecting the
internal optical and electronic components of the Safe 2 light curtain.
The best performance of the shock and vibration isolation kit is attained
when the kit is used in conjunction with the Safe 2 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%.
