Installation Instructions
Step 1:  Prepare for Installation
IMPORTANT!
Perform the following steps BEFORE installation of the monitor into the panel�
1� Ensure that sufcient power is available�
2� Ensure that sufcient space is available to allow for proper air ow into and out of the
unit�
3� Ensure that the air temperature around the unit (top and bottom) will not exceed the
rated specications of the unit.
f The maximum rated temperature for the HIS-ML20 is 50°C (122°F)�
f Remember  that  heat  rises  –  the  temperature  at  the  top  of  the 
cabinet  will  be  much  hotter  than  at  the  bottom  if  air  inside  the  enclosure is not actively circulating�  Even in a sealed enclosure,  use of a circulation fan can greatly reduce temperature�
f Also,  remember  that  even  though  this  product  is  designed  to 
operate at 50°C, the life span of any electronic device is shortened  when it is consistently operated at high temperatures�  Therefore,  it is wise to take steps to keep the temperature of the ambient air  around the unit as low as possible�
4� Ensure that the ambient humidity of the air around the unit does not exceed the
specications of the unit.
f The  maximum  rated  humidity  for  the  HIS-ML20  is  90%
