v This equipment must be installed by trained service personnel in a
restricted-access location, as defined by teh NEC and IEC 60950, The
Standard for Safety of Information Technology Equipment.
v
Connect the equipment to a reliably grounded, safety extra low voltage

that normal and single fault conditions do not cause the voltages to exceed
a safe level (60 V direct current).
v
The branch circuit overcurrent protection must be rated per the following
table.
v Use copper wire conductor only, not exceeding 3 m (9.8 ft.) in length and
sized according to the following table.
