Site Preparation
Before installing the switch or switches, make sure that the chosen
installation location meets the following site requirements:
•
Clearance — There is adequate front and rear clearance for operator
access. Allow clearance for cabling, power connections, and ventilation.
•
Cabling — The cabling is routed to avoid sources of electrical noise such
as radio transmitters, broadcast amplifiers, power lines, and fluorescent
lighting fixtures.
•
Ambient Temperature — The ambient switch operating temperature
range is 10° to 35ºC (50° to 95ºF).
NOTE:
Decrease the maximum temperature by 1°C (1.8°F) per 300 m (985 ft.)
above 900 m (2955 ft.).
•
Relative Humidity — The operating relative humidity is 8% to 85%
(non-condensing) with a maximum humidity gradation of 10% per hour.
