Motorola Solutions Inc. 99FT4100 Manual De Usuario
The environmental conditions are:
• Operating Temperature Range – Vertical orientation
-30 °C (-22 °F) to +60 °C (+140 °F)
The operating temperature range is the temperature measured close to the repeater, near the fin
inlets (bottom). Other factors, such as orientation, solar loading, duty cycle, and VSWR can affect
transmit power and/or maximum operating temperature range.
inlets (bottom). Other factors, such as orientation, solar loading, duty cycle, and VSWR can affect
transmit power and/or maximum operating temperature range.
• Ingress
The repeater has been designed to IP65 ingress protection. It provides protection against blowing
water and dust and can be deployed in harsh industrial indoor environments and/or outdoor
applications where rain, snow, and dust are prevalent.

applications where rain, snow, and dust are prevalent.
• Vibration and Loads
The repeater hardware has been designed to survive high vibration and wind loads (up to 150 mph)
encountered in outdoor environments and may be installed in vehicular environments when
equipped with ruggedized mounting brackets or trunnions.

10.1.3
Equipment Ventilation
The SLR 1000 Repeater is a natural-convection or passively cooled device with no fans. Care must be
taken in mounting the unit to ensure that fresh air can flow into the fin entrances and heated air can
adequately escape.

10.1.3.1
Ventilation for a Ceiling Mount
Ceiling mounting of the SLR 1000 Repeater requires that the bracket is mounted against the ceiling
surface and that the unit is positioned with the fins facing up towards the ceiling.
surface and that the unit is positioned with the fins facing up towards the ceiling.
Fresh air flows into both ends of the fins and the heated air exhausts out the top of the fin channels.
The mounting bracket (same as used for the wall mount) provides an adequate gap between the unit
fin tips and the ceiling surface. The fin cooling effectiveness in this orientation is slightly lower than
vertical wall mount orientations and that some power shutback at high ambients may occur. It is not
recommended to mount any optional AC power supplies onto the mounting bracket when in a ceiling
orientation, as the exhaust air is restricted from rising and could overheat the power supply unit as well.

and that the unit is positioned with the fins running vertically.
Fresh air flows into the bottom of the fins and the heated air exhausts out the top of the fin channels.
Mounting of the unit with the fins running horizontally or other orientations other than vertical reduces
the airflow through the fins and that some power shutback at high ambients may occur. The wall mount
bracket provides adequate gap and mounting provisions for integration of an optional AC power supply
between the fins and the bracket. As airflow occurs bottom to top, this does not impact thermal
performance in the vertical orientation.
