General Installation Notes 

WARNING:

  Disconnect all sources of power 

before installing or servicing the AV-V70. 

DO NOT install/remove circuit cards or 
transformers while the AV-V70 is supplied with 
power. 

ENVIRONMENT:  

INSTALL the equipment in a 

clean, dry environment.  

The equipment meets the requirements for 
operation at 32°F - 120°F (0°C - 49°C) and relative 
humidity of 85% RH. 

WIRING:

  CHECK that the installation wire sizes 

are adequate to deliver the required load current 
and maintain compatibility with the specific device 
operating voltages. 

USE an anti-static wrist strap 
whenever handling circuit cards. 

STORE circuit cards in static 
suppressive packaging. 

 

A secure dedicated ground connection is 
required. Although no system is immune 
to the effects of lightning strikes, a 
secure ground connection will reduce 
susceptibility. The use of overhead or 
outside aerial wiring is not 
recommended.

Enclosure 

Mounting 

When mounting the AV-V70 enclosure, ensure that there is sufficient space to allow the cover to be opened / 
removed after installation. If the cover is completely removed remember to reconnect the earth/ground wire when 
reinstalling. The AV-V70 universal audio converter panel enclosure is designed for surface mounting. 

There are three (3) mounting holes located on the back wall of the AV-V70 enclosure/back box (see figure 3). The 
top center mounting hole is keyed for ease of mounting. Place the back box on the wall and mark the top center 
keyed mounting hole. Drill the marked location and partially install the mounting screw in the wall. 

Hang the enclosure on the center mounting screw. Level the enclosure and mark the remaining two mounting holes 
(on the bottom).  Drill the remaining holes and insert all screws and firmly tighten. 
 

Caution:  If drilling while mounting the AV-V70 enclosure is going to make any metal filings or other PC 
board contaminants, remove all circuit cards from the enclosure.
