1.3. Safety Information
1.3.1. General
• Read this user manual and follow all operating and safety instructions.
• The base station and antenna must be installed by a professional installer.
• Do not exceed the described limits.
1.3.2. Power Supply Requirements
• The power supply unit should be a Class 2 power supply, safety-certified according to national
codes.
• Maximum output current should not exceed 5A.
• Maximum output voltage of the power supply should not exceed 60VDC.
• Minimum output voltage should not be below 42VDC.
• The disconnecting device is defined as the following:
• When connected to an AC/DC power supply, the appliance coupler of the AC/DC power
supply is regarded as the main disconnecting device for the base station.
• When connected to a DC battery power supply, a double pole circuit breaker, rated 10A
60VDC, is regarded as the main disconnecting device for the base station.
The unit is considered to be connected to a centralized DC power system, therefore the power line
should be grounded. The unit should be permanently connected to ground with 16AWG cable or
less. See the figures below for two methods of power grounding (from the UL 60950-1 standard;
according to UL 60950-22). When the unit is connected to a centralized DC Power System, the
"+" side of the supply should be grounded, as per UL60950-1 and UL 60950-22 requirements.
