2.     CONFIGURATION AND INSTALLATION 

CAUTION:         IF YOU ARE INSTALLING FR1000 FRAMES AND PS2001 

POWER SUPPLIES IN ADDITION TO NV1023 
DISTRIBUTION AMPLIFIERS AT THIS TIME, YOU 
SHOULD FOLLOW THE SYSTEM-LEVEL 
INSTALLATION PROCEDURES FOUND IN THE NV1000 
TERMINAL EQUIPMENT OPERATIONS INSTRUCTION 
MANUAL (MANUAL PART NO. MI1000-01) LOCATED IN 
THE FRONT OF THIS BINDER. 

CAUTION:         REMOVE POWER FROM THE FRAME IF THE 

INSTALLATION INCLUDES THE CONNECTOR 
BACKPLANE. 

1.          Replace the blank cover plates on the rear of the intended slot in 
the NV1000 frame with the backplane assembly for the NV1023 
distribution amplifier. The FR1000 frame is supplied with a 2.5 mm 
Allen wrench for this purpose. Ensure proper alignment of the active 
module to the backplane with the following procedure: 

a.    Install the EM0104 backplane with the screws loose. 

b.    Plug the active module into the loose backplane. 

c.    With the active module inserted, tighten the screws securing the 

backplane. 

d.    Remove the module and reinsert it to make sure it is properly 

aligned with the backplane and the card guides in the frame. If 
the alignment is not good, repeat the above procedure. When a 
satisfactory fit is obtained, remove the module and continue 
with the installation. 

2.    Make cable connections to the rear panel per the drawings included 

in the Applications section (See Section 1.2). 

3.    Set the input termination jumper on the active module as required 

by the application. Refer to Table 2 - NV1023 Jumper Setting and 
the Component Location drawing in Section 6 for information on 
the jumper location and setting. 

4.   Apply AC line power to the frame and insert the PS2001 power 

supply if it is not already in place. 

5.    Insert the active module with power applied to the frame.
