1.2.7
Ventilation Requirements: The rectifiers are fan cooled and utilize front to back forced ventilation. The
power/distribution bays and power only bays must be mounted so ventilating openings are not blocked and
temperature of the air entering the rectifier shelf does not exceed the operating ambient temperature range stated
above.
Also, the distance from the rear of a power/distribution bay or power only bay to a wall or other solid structure
must not be less than 6 inches. This will assure proper air flow through the rectifiers.
1.2.8
Audible Noise: The audible noise does not exceed the following when measured at any point two feet from any
vertical surface of a power/distribution bay and five feet from the floor using a sound level meter conforming to
ANSI S1.4.

1.2.9
EMI/RFI Suppression: Rectifiers operating in a Power/Distribution Bay conform to the requirements of FCC rules
Part 15, Subpart B, Class A for Radiated and Conducted emissions limits.
1.2.10
Surge Protection
(A)
Standard: Compliance with EN61000-4-5 Installation Class 4, and capable of withstanding surges per
ANSI/IEEE C 62.41-1991 Category B across the input terminals.
Note: This level of protection is a widely used standard for telecommunications power equipment. As with
all such equipment, it is the end user's responsibility to provide an adequately sized Surge
Suppression Device at the commercial power service entrance of the building that reduces all
incoming surges to levels below the classes/categories stated for the equipment.
(B)
When Equipped with List 35, 36, 37, or 38: Compliance with EN61000-4-5 Installation Class 4, and capable of
withstanding surges per ANSI/IEEE C62.41-1991 Category A, Category B, and Category C, and ANSI/IEEE
C62.41.2 Scenario II, Exposure 3, 100KA 8/20us, 10KA 10/350us.
1.2.11
ESD Protection: Complies with EN61000-4-2 Level 4 (8kV contact).
1.2.12
Electrical Fast Transient / Burst Immunity: Complies with EN61000-4-4 Level 4.
1.2.13
Mounting: This power system is intended only for installation in a restricted access location on or above a non-
combustible surface. Typical industry standards recommend minimum aisle space clearance of 2'6" for the front of
the relay rack and 2' for the rear of the relay rack.
