1.2.3Air Quality
For equipment operating in an area which is environmentally controlled and with the repeater(s) rack mounted, the airborne particle level must not exceed 25 µg/m³.
For equipment operating in an area which is not environmentally controlled and with the repeater(s) cabinet mounted, airborne particle level must not exceed 90 µg/m³.

C a u t i o n
If the repeater is to be installed in an environment which is usually dusty, dirty, or does not meet the air quality requirements, then the air used to cool the repeater modules must be treated using appropriate filtering devices. Dust or dirt accumulating on the internal circuit boards and modules is not easily removed, and can cause such malfunctions as overheating and intermittent electrical connections.
1.3Equipment Ventilation
The repeater is equipped with a cooling fan that is used to provide forced convection cooling. When planning the installation, observe the following ventilation guidelines:
•
•All cabinets must have a least 15 cm (6 inches) of open space between the air vents and any wall or other objects.
•When multiple cabinets (each equipped with several repeaters) are installed in an enclosed area, ensure appropriate ventilation and consider air conditioning or other climate control equipment to satisfy the temperature requirements stated under Section 1.2.1 Operating Temperature Range on page
1.4AC Input Power Requirements
The repeater is equipped with a switching power supply, and this assembly operates from 100 – 240 VAC at 47– 63 Hz AC input power. A standard

C a u t i o n
The outlet must be connected to an AC source capable of supplying a maximum of 280 W. For a nominal 110/120 VAC input, the AC source must supply 5 A and should be protected by circuit breaker rated at 15 A. For a nominal 220/240 VAC input, the AC source must supply 3 A and should be protected by a circuit breaker rated at 10 A.
1.4.1Circuit Overloading
Consideration should be given to the effects of overloading on overcurrent protection devices and supply wiring. Appropriate consideration of equipment ratings should be used when addressing this concern.
1.5Equipment Mounting Methods
The MOTOTRBO Repeater may be mounted in a rack, bracket or cabinet (available as accessories).
