Accessing and Changing On-Card Fuse - The primary fuse is in the AC connector fuse box
(Figure 2.3, Section 2.5.2). Figure 2.4 shows the secondary fuse on the power supply.
To remove the power supply from the extrusion for access to the secondary fuse:
1.) Remove four (4) rear panel screws (see Figure 2.1).
2.) Gently pull the power supply assembly completely out of the extrusion.
3.) With AC Power disconnected, replace fuse with a 2.0 amp fuse (Figure 2.4).
4.) Gently push the power supply assembly completely in to the extrusion.
5.) Install four (4) rear panel screws.

Installation / Operation -
2.5.1
Installing and Operating the 2000-12 1.) Connect the DC power to the Series 2000 unit.
2.) Connect the 2000-12 to 100-240 ±10% VAC, 43 - 60 Hz.
3.) Be sure DS1 (green, DC Power) is on (Figure 2.2).
2.5.2
Replacing the fuse in the rear panel fuse box (Figure 2.3) 1.) Remove the 100-240 ±10% VAC, 43 - 60 Hz to the 2000-12
2.) Pull out the fuse box below the AC input connector (Figure 2.3).
3.) Pry out the fuse in the back slot and measure it to see if it is open.
4.) If the fuse is open determine the cause of the blown fuse and repair this.
5.) After the cause of the blown fuse is corrected, replace the open fuse with the
2.0 amp fuse in the front section.
6.) Apply 100-240 ±10% VAC, 43 - 60 Hz to the 2000-12 and be sure DS1
(green, DC Power) is on Figure 2.2.

3.0 Environmental Use Information
A. Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions
located in the user manual furnished by the manufacturer of your equipment rack.
B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition
does not exist due to uneven weight distribution.
C. Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack may be greater than room ambient temperature.
Therefore, consideration should be given to Tmra.
D. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised. Additional space between units
may be required.
E. Circuit Overloading - Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of circuits could have on over current protection and
supply wiring. Appropriate consideration of equipment name plate rating should be used when
addressing this concern.
F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connection to the
Branch (use of power strips).
G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be
removed. If the Top Cover is removed the ground strap and associated screw MUST BE
REINSTALLED prior to Top Cover screw replacement. FAILURE TO DO this may cause
INGRESS and/or EGRESS emission problems.
