EMC DS-16B manual Site Considerations, Cooling, Power Requirements

Installation

Site Considerations

Cooling		Cooling air is drawn into the chassis by four fans mounted near the
Requirements		rear of the chassis, venting exhausted air through the front of the
		switch.
		Do not block the front or rear air vents. The switch must have free access to
		ambient air for cooling.
Power Requirements		Switch power connection is via switched connectors on the switch’s
		front panel, as shown in Figure 2-1. The switch power requirements
		are:
		• Properly wired, earth-grounded outlet
		• Input voltage: 85 – 265 VAC
		• Total power: Up to 155 watts (depending on configuration, see
		Appendix A, Specifications)
		• Input line frequency: Nominally 47 to 63 Hz
		The switch has an autoranging power supply that automatically
		accepts voltages and line frequencies within its range. A green power
		on indicator light is above the power switch.

The switch meets IEC 801-5 surge voltage requirements, however, there is no other provision for surge protection built into the switch’s power supplies. An installation should include normal provisions to assure clean power.
