Danger:
• Only trained and qualified electrical service personnel should perform wiring and
cabling to the system.
• All power to the equipment rack or cabinet should be disconnected before the
installation.
• The power cables must be copper and meet your local electric code requirements.
• The circuit breaker is not intended to be used as the chassis ON/OFF switch.
Disconnect the power from the power source to remove power.
• The 7750 SR-a routers with DC PSU modules should be installed only in restricted
access areas (such as dedicated equipment rooms and electrical closets).
• An external circuit breaker no greater than 60 A must be located within a readily
accessible distance of the equipment. This is intended as the disconnect device.
• A disconnect device must be provided within 9.84 ft (3 m) of the 7750 SR-a chassis.
• A #8 AWG (maximum) power conductor must be provided for each of the DC input
connections.
The following AC power cord requirements are applicable to all countries:
• The length of the power cord must be at least 6 ft (1.8 m) and a maximum of
9.75 ft (3.0 m).
• All power cords must be approved by an acceptable accredited agency responsible
for evaluation in the country where the power cord set is used.
• The power cord must have a minimum current capacity of 10 A and a nominal
voltage rating of 220 or 240 VAC, as required by each country's power system. The
power cord must have a minimum current capacity of 12 A for 100V-120 VAC.
• The appliance coupler must meet the mechanical configuration of an EN 60 320/IEC
320 Standard Sheet C13 connector for mating with appliance inlet on the unit.
• The power cord set used with this 7750 SR-a must meet the local safety code and
requirements.
