CAUTION:
To reduce the risk of electric shock or energy hazards:
v This equipment must be installed by trained service personnel in a
restricted-access location, as defined by the NEC and IEC 60950, The
Standard for Safety of Information Technology Equipment.
v Connect the equipment to a reliably grounded, safety extra low voltage
(SELV) source. An SELV source is a secondary circuit that is designed so
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.
v Torque the wiring-terminal screws to the values in the following table.
v Incorporate a readily available approved and rated disconnect device in the
field wiring.
