Chapter 5 Electrical installation
• To meet the requirements of the relevant product standards (e.g. EN 61 496­1), the
external voltage supply for the devices (SELV) must be able to bridge a brief mains
failure of 20 ms. Power supplies according to EN 60 204­1 satisfy this requirement.
Suitable power supplies are available as accessories from Rockwell Automation (see
“Accessories” section on page 53).
• Dimension the electrical protection for the camera to suit the information in the
“Data sheet” section on page 47.

Table 9 - Pin assignment system connection SC300
Note Connecting cables of different length are available as accessories from Rockwell
Automation (see “Accessories” section on page 53). If you use connecting cables you have
assembled yourself, ensure the functional earth (pin 8) is connected.
Connecting the SC300 Without external device monitoring (EDM), without internal restart interlock
and without external key-operated pushbutton for teach-in
Note If you use the SC300 without the internal restart interlock, then you must implement the
restart interlock externally, i.e. machine-side.
