The ONS 15216 EDFA2 is intended for installation in a restricted access area. A restricted access area
Warning
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:
Mount the ONS 15216 EDFA2 in the rack (19 inches or 23 inches reversible ears). Empty rack space is
Step 1
not required above or below the ONS 15216 EDFA2.
Connect the –48 VDC power cable to the office fuse panel (user-provided).

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.).
1.0A fusing is required (user-provided).
Use 18 AWG stranded wire (and wire lugs as appropriate).
