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%
(non­condensing) with a maximum humidity gradation of 10% per hour.
