FF-SPS4 Series Installation Manual

Power Supply Wiring

The FF-SPS4 Series safety perimeter guarding devices operate at 115 VAC. A low voltage
version (24 VDC) is also available. All of the safety perimeter devices have the same
connection for power. The low-voltage perimeter devices have a reverse polarity protection
feature to ease installation.
The ground connection cable should be at least equal to the voltage supply cable and the
cable length should be as short as possible. A screw is located inside the housing of the
terminal strip at the bottom on the lens side. On the quick-connect version, the ground must
be connected to the screw on the connector. Refer to figure 3-4 for power connections.
To ensure the specified immunity to electrical noise, the ground terminal of FF-SPS4 must be
connected to the main ground of the machine.
