Installing External Power Supplies
independently-fused circuits must be within 6 feet (1.8 meters) from the installation site. If there is an
AC power source failure, this will prevent the powering down of redundant power supplies due to a
single source power failure.
•
Power cords and type of outlet are dependent on the country. In the United States, one power cord
with an NEMA 5-15P plug is provided with each STK-RPS-150PS.
•
An ambient temperature of between 32°F (0°C) and 122°F (50°C) must be maintained at the
installation site with fluctuations of less than 18°F (10°C) per hour.
Rack Mounting the RPS Shelf
To install the RPS shelf into a 19-inch (48.3 cm) rack:
1. Position the RPS shelf between the vertical rails and align the mounting holes in the RPS shelf
brackets with those in the rack frame.
2. Fasten the RPS shelf securely to the rails using the customer-supplied mounting screws (four for the
STK-RPS-150CH2, ten for the STK-RPS-150CH8).

Caution
To ensure proper ventilation and prevent overheating, leave a minimum clearance space of
3 inches (7.6 cm) at the front and rear of the unit.
Warning
Before installing the shelf into a rack, ensure that the rack can support the device(s)
without compromising the stability of the rack. Otherwise, personal injury and/or
equipment damage may result.
