Power Supply Wiring
All of the FF-SM Series mats have the same connections for power. Figure 3-2 illustrates the
power connections. The fuse on the power line provides additional protection (400 mA/AC or
800 mA/DC).
•
The wire gauge of the ground connection should be equal to the power supply wire gauge.
•
The length of the ground connection wire should be as short as possible (refer to EN 60
204).
•
To minimize noise interference, the ground terminal of the mat must be connected to the
main ground of the machine.
•
Snap-in clip connections do not require tinning of wires.
FF-SM Series safety mats operate on 120 (+10%, -20%). or 240 volts AC (+10%, -20%). A
24 volt (+ 15%) DC version is also available. DC versions are equipped with DC/DC
converters to provide the galvanic insulation made mandatory by IEC64196 European
norms for type 4 equipment. An additional galvanic insulated means (a dedicated
power supply with a DC/DC converter) is not required.
The frequency range is from 50 to 60 Hz. Power consumption is either 6 VA (AC) or 9 W
(DC). When wiring, use (1.5 mm
2
)
16 or (1 mm
2
)
18 gauge wire.
