Step 1: Prepare for Installation
IMPORTANT!
Perform the following steps BEFORE installation of the monitor into the panel.
1� Ensure that sucient power is available.
2� Ensure that sucient 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 specications of the unit.
f The maximum rated temperature for the HIS-ML23.8 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
specications of the unit.
