DANGER! WHEN INSTALLING THE WIDE BANK, BE SURE TO OBSERVE STANDARD

SAFETY PROCEDURES FOR WORKING WITH ELECTRICAL EQUIPMENT.

Rack mounting is the only recommended method for mounting the Wide Bank. The different

recommended configurations for rack mounting are:

Standard, non-FFO units:

 Horizontal mounting in a 19-inch or 23-inch rack. This method is limited by specific guidelines

described in the mounting procedures that follow.

 Vertical mounting in a 19-inch or 23-inch rack. This method allows up to 24 units to be mounted

in a single rack, depending on environmental factors.

FFO-equipped units:

 Horizontal mounting is the only recommended configuration for FFO-equipped units. FFO-

equipped units do not require a 1 RU space between units, which results in the highest density

installation method.

Before mounting the Wide Bank chassis, ensure that the installation site meets the following criteria:

 Adequate clearance for maintenance access, cable routing, and air flow to cool the unit. Allow

approximately 30 inches in front of the removable control panel for maintenance and accessing

the slide-in cards. Allow approximately 24 inches in the rear for cable access and bending radius.

 Because the cables on the Power Converter/Battery Charger total 12 feet in length, there should

be a properly grounded, 120 VAC power outlet within 11 feet of the Wide Bank power connectors,

unless power is supplied by other power conversion equipment that has longer cables.

 A stable environment, clean and free from extremes of temperature, shock, vibration, and EMI,

with a relative humidity between 0 and 98%.

 An appropriate ambient air temperature for the mounting method used. The Wide Bank 28 DS3

operates throughout the NEBS operating temperature range unless otherwise specified in the

installation descriptions below.

NOTE: If the operating temperature rises above 176

º F

(80

C), an Over-Temperature

alarm is generated. When the temperature is reduced below 176

º F

(80

C), the Over-

Temperature alarm will clear.

 An altitude below 15,000 ft. (4,572 m).
