Installation Instructions
Step 1: Prepare for Installation
IMPORTANT!
Perform the following steps BEFORE installation of the monitor into the panel.
1�
Ensure that sufficient power is available.
2�
Ensure that sufficient space is available to allow for proper air flow into and out of the
unit�
3� Ensure that the air temperature around the unit (top and bottom)
will not exceed the
rated specifications 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
specifications of the unit.
f
The maximum rated humidity for the HIS-ML20 is 90%
non-condensing.
