Unpacking

Your ALTER 500 has been carefully and meticulously tested and inspected before dispatch.

Compatibility and Power 

 
The ALTER 500 module is designed to be installed into an API™ 500 Series compatible rack
and cannot function stand alone, requiring the power source supplied by the rack system. 
The current consumption of the ALTER 500 is rated at 120 miliamperes per slot. Please check
with the rack manufacturer that the design can meet this rating. 

Mounting

WARNING!

You may destroy your unit permanently!

The dimensions of all IGS Audio 500 series modules are compatible with API standard. When
plugging   your   new  unit   to   the   500-series   rack,   no   unnecessary  force   is   needed.   However,
please   be   careful   and   do   not   rush   while   pushing   the   unit   into   the   rack   sockets,   to   avoid
damaging  of the connectors and/or the PCBs of either the unit or the rack.  

After the unit is placed in the rack, use the screws provided with your 500-series rack unit to
make sure that the unit is safely placed.

When removing the unit from the rack, unscrew the front panel from the rack, and use your
fingers to pull it out gently. Do not use any sharp objects (i.e. knives or screwdrivers) to prize it.
