NFORMATION
This equipment is not intended for use with IT power distribution systems whose
line to line voltage exceeds 250 VAC RMS defined by EN 60950 as having no
direct connection to earth. The PathBuilder S330/S310 switch will auto-configure
for 115 VAC or 220-240 VAC.
North American Applications — Use a UL Listed and CSA Certified Cord Set
rated 6 amps, consisting of a minimum 18 AWG, Type SVT or SJT three
conductor cord maximum of 15 feet in length, with a NEMA 5-15P plug.
International Applications — The power supply cords used with this
equipment should be harmonized with all local standards applicable in the
country in which it is installed.
Safety agency compliance requires this unit to be connected to branch circuits
with overcurrent protection ≤ 20A for North American applications and ≤ 10A for
international applications.
The power supply cord must be disconnected when servicing all components or
subsystems.
FCC — This equipment generates, uses, and can radiate radio frequency
energy, and if not installed and used in accordance with the instruction
manual, may cause interference to radio communications. It has been tested
and found to comply with the limits for a Class A computing device pursuant
with Part 15 of the FCC Rules, which are designed to provide reasonable
protection against such interference when operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause
interference, in which case the user at his own expense will be required to take
whatever measures may be required to correct the interference. These tests
were conducted with shielded communications cables with metal connector
hoods; the use of unshielded cables may void this compliance.
Canada —This digital apparatus does not exceed the Class A limits for radio
noise emissions from digital apparatus set out in the Radio Interference
Regulations of the Canadian Department of Communications.
Europe —This is a Class A product. In a domestic environment this product
may cause radio interference, in which case, the user may be required to take
adequate measures.
The following port types in the product range are classified according to the
Harmonized Europeans Standard EN41003, subclause 4.1.3, as follows:
E1/E3 —TNV normally operating within SELV limits (TNV-1)
