This product meets the UL/cUL 62368 / IEC 62368 edition 2
specification, and the radio housings are designed to be rain-tight.
Force 300-19 heater
At startup, if the Force 300-19 module temperature is at or below 32°F (0°C), an internal heater is
activated to ensure that the device can successfully begin operation. The unit’s heater is only activated
when the unit is powered on and will not apply heat to the device once the startup is complete. When the
unit temperature is greater than 32°F (0°C), the heater is deactivated, and the unit continues its startup
sequence.
The effect on device startup time at various temperatures is defined in Table 49.

Force 300-19 wind loading
Ensure that the device and the structure on which it is mounted are capable of withstanding the
prevalent wind speeds at a proposed ePMP site. Wind speed statistics are available from national
meteorological offices.
The device and its mounting bracket are capable of withstanding wind speeds of up to 180 kph (113 mph).
Wind blowing on the device will subject the mounting structure to significant lateral force. The
magnitude of the force depends on both wind strength and the surface area of the device. Wind loading
is estimated using the following formulae:
Force (in kilograms) = 0.1045aV

the surface area in square meters
wind speed in meters per second
Force (in pounds) = 0.0042Av
