•Mechanical Loading—Mounting of the equipment in the rack should be such that it avoids uneven mechanical loading.

•Circuit Overloading—Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used.

•Reliable Earthing—Reliable grounding of rack mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (i.e., use of power strip, etc.).

Warning The ONS 15216 EDFA2 is intended for installation in a restricted access area. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock, key, or other means of security. A restricted access area is controlled by the authority responsible for the location.

3.3.2 Rack Installation and Power Supply Connection Procedures

Warning Before performing any of the following procedures, ensure that the power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Follow these steps to install the ONS 15216 EDFA2 into the rack and correctly set up the power supply:

Step 1 Mount the ONS 15216 EDFA2 in the rack (19 inches or 23 inches reversible ears). Empty rack space is not required above or below the ONS 15216 EDFA2.

Step 2 Connect the –48 VDC power cable to the office fuse panel (user-provided).

a.1.0A fusing is required (user-provided).

b.Use 18 AWG stranded wire (and wire lugs as appropriate).

Step 3 Connect power cable from the office fuse panel to the power bus A terminals on the ONS 15216 EDFA2. See Figure 2-2 on page 2-5.

Step 4 Repeat Step 3 for power bus B.

Step 5 Connect the facility ground to the ONS 15216 EDFA2 side panel ground using #10-32 x 3/8-inch fasteners with lock washers and ground lugs, or connect to the rear panel ground using ring lugs for #8 studs.

Step 6 Insert 1.0A fuses into the fuse panel (user-provided).

The Power LED on the front panel of the ONS 15216 EDFA2 should illuminate when the power is supplied.
