CHAPTER 2 ULTRA 4 INSTALLATION 
Unpacking 
Power Supply Requirements 
Ultra 4 can operate from AC supply or from a DC supply or battery.  The 
rated AC range is between 100V and 240V 50/60Hz. The DC range is 10 – 
28V.  In both cases the Ultra 4 will typically consume 6W of power, with a 
maximum of 10W. 
Location 
When choosing a location to mount the enclosure, please bear in mind the 
following: 
•  Ensure that the Ultra 4 is installed in a “Safe”, non-hazardous, area. 
•  For a clear view of the display, it is recommended that it is mounted 
at eye level. 
•  The mounting surface is vibration-free. 
•  The ambient temperature is between -20ºC and 45ºC (-4
o
F and 
113
o
F). 
•  When installing the fascia, remember the temperature within an 
equipment cabinet may be higher than the outside ambient, 
depending on the heat generated within and ventilation provided. 
•  There should be no high voltage cables or inverters close by. 
•  There should not be any heat-generating components nearby. 
Important Information 
All shipping cartons should be opened carefully. When using a box cutter, do not 
plunge the blade deeply into the box, as it could potentially cut or scratch 
equipment components. Carefully remove equipment from each carton, 
checking it against the packing list before discarding any packing material. If 
there is any shortage or obvious shipping damage to the equipment, report it 
immediately to your local Pulsar distributor.
