Mounting site and climatic conditions
The conditions at the mounting site must meet the requirements specified in the technical data.
•
As far as possible, the mounting site should be vibration-free to prevent the screw connec-
tions from working loose.
• The mounting site should be free from aggressive media, e.g. acids and lye, and, if possi-
ble, free from dust, flour, and other suspended matter to prevent the cooling slots from being
blocked.
• At the mounting site, ensure a minimum clearance of 100 mm above the device to allow the
access to the unlocking slot required for dismounting with a screwdriver. Maintain a mini-
mum clearance of 150 mm if the antenna is fitted directly on the receiver. Several receivers
can be fitted next to each other without clearance spacing. (Attention: When several anten-
nas are fitted directly, they may interfere with each other).
The ambient temperature range at the mounting site may be -20 to +50 °C with a relative hu-
midity of
≤ 85 % without condensation.
