D Selecting the Installation Site
Maintain an ambient temperature of 0 to 50 _C. Don't forget to allow for other heat sources
in the vicinity. Remember that if instruments are stacked on top of each other with little or no
gap between them, additional heat will be generated. The front and rear of the controller
should have good accessibility.
