12.0 INSTALLATION
 
The X75 can be mounted in either 19” or 23” racks by using the supplied brackets. Mount 
it from the front of the rack using the correct offsets to align with existing rack-mounted 
equipment.  Once mounted in the rack the following connections must be made with the 
unit switched off.
 
CAUTION: Re-read the Safety Warnings and Precautions in Section 3. All power
should be OFF for the input and output loads before making connections. Connection
of the X75 chassis to frame ground should be made first. If the X75 has been turned
on before installation connections, it should be turned off and given a 5-minute waiting
period for all internal energy storage capacitors to be discharged.
12.1 
Input AC Power Connection
 
A 3-wire AC power line should be connected to the input IEC connectors but not 
plugged into the AC power source.  The line, neutral and ground connections should 
be carefully observed when making the AC connections. The AC line cord should 
be sized to safely carry 15 amperes AC each, minimum.

12.2  Checking Outputs
 
 
Turn all output circuit breakers to the OFF position and/or remove all fuses from the 
GMT fuse-holder.  With no loads connected and without the battery connected, plug 
in or connect the AC input cords one at a time to the AC power source.  Be sure to 
use the correct AC voltage for the rectifier inputs.
 
Using a volt meter measure the DC voltage reading across the –VO and +VO bus bars 
at the rear of the unit.  The voltage should be approximately 54.4, 27.2, or 13.6VDC 
(depending on model), which is the factory setting.
