FORCE 200 HEATER
Upon power on, if the ePMP Force 200 device temperature is at or below 32° F (0° C), an internal
heater is activated to ensure that the device is able to 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
startup is complete. When the unit temperature is greater than 32° F (0° C), the heater is
deactivated and the Force 200 module continues its startup sequence.
The effect on Force 200 startup time at various temperatures is defined in
Table 48 .
Table 48 Force 200 startup times based on ambient temperature
Initial Temperature Startup time (from power
on to operational)
-22° F (-30° C) 4 minutes
-4° F (-20° C) 2 minutes
14° F (-10° C) 1 minutes, 30 seconds
FORCE 200 WIND LOADING
Ensure that the Force 200 and the structure on which it is mounted are capable of withstanding the
prevalent wind speeds at a proposed ePMP site. Wind speed statistics must be available from
national meteorological offices.
The Force 200 and its mounting bracket are capable of withstanding wind speeds of up to 145 Kph
(90 mph).
Wind blowing on the Force 200 will subject the mounting structure to significant lateral force. The
magnitude of the force depends on both wind strength and surface area of the integrated module.
Wind loading is estimated using the following formulae:
Force (in kilograms) = 0.1045aV 2
Where: Is:
a surface area in square meters
V wind speed in meters per second
