Installation
This section of the manual is intended to help you plan your tasks to facilitate the installation.
Please read this section thoroughly, especially if you are installing a SKE-450 control for the
first time.
3.1 Environmental Specifications
It is important to protect the SKE-450 control panel from moisture. To prevent damage, the
following conditions should be avoided when installing the units:
• Mount indoors in dry locations only
• Do not mount directly on exterior walls, especially masonry walls (condensation)
• Do not mount directly on exterior walls below grade (condensation)
• Protect from plumbing leaks
• Protect from splash caused by sprinkler inspection ports
• Do not mount in areas with humidity-generating equipment (such as dryers, production
machinery)
When selecting a location to mount the panel, it should be mounted where it will NOT be
exposed to temperatures outside the range of 0°C-49°C (32°F-120°F) or humidity equal to or
greater than 93% at 30°C (89°F) noncondensing.
3.2 Electrical Specification
* Specify voltage requirements when ordering.
Note: Refer to the control panel wiring diagram to determine which power source is required for your control.
