When you add or replace a power supply unit in your system, be sure to verify the supply's features and
that the PWR-XXXX part numbers match to ensure that you have the correct supply.
Guidelines for AC-powered equipment
An AC-powered installation must meet these requirements:
• Use a 15 amp external branch circuit protection device to install the unit.
• Use one power feed for each individual power supply.
Important: The platform must be installed in a RESTRICTED ACCESS LOCATION, such as a central
office or customer premises environment.
Note: The power cables included with this unit are for exclusive use with this unit and should not be used
with other electrical appliances.
Note: These guidelines apply to STATIONARY PLUGGABLE EQUIPMENT TYPE A with simultaneous
multiple connections to the AC MAINS SUPPLY:
• The building installation shall provide a means for connection to protective earth; and
• The equipment is to be connected to that means; and
• A SERVICE PERSON shall check whether or not the socket-outlet from which the equipment is to be
powered provides a connection to the building protective earth. If not, the SERVICE PERSON shall
arrange for the installation of a PROTECTIVE EARTHING CONDUCTOR from the separate protective
earthing terminal to the protective earth wire in the building.
Caution: High leakage current. Earth connection essential before connecting supply.
Guidelines for DC-powered equipment
A DC-powered installation must meet these requirements:
• Use a 15 amp external branch circuit protection device to install the unit.
• For permanently connected equipment, incorporate a readily accessible disconnect in the fixed wiring.
• Use only copper conductors.
• Cabling for the system must be grounded on both sides.
• Use one power feed for each individual power supply.
Caution: Install DC-powered equipment only in restricted access areas, such as dedicated equipment
rooms, equipment closets, or similar locations.
