Page 3: General Description
The SA5A must powered with an external AC- or DC- power supply. Environmental SA5A is built in a small metal carry case designed for rough handling in tough outdoor environments. All connections are protected for any possible type of electrical discharges and disturbances. Some of the inputs are even protected against faulty connections up to 300V peak. -

• Connections. Before connecting the SA5A to a high-voltage circuit breaker, make sure that the breaker poles are in position CLOSE, and disconnected from the power line at both sides. The breaker must also be grounded on at least one side. -
Page 5: Power Supply And Protective Grounding
2.2 POWER SUPPLY AND PROTECTIVE GROUNDIN G The SA5A can be powered from any AC or DC source, 100-250 V. When the SA5A is connected to a wall socket, the socket must be a grounded power outlet. IMPORTANT! The SA5A have a separate grounding terminal (green/yellow) that must be grounded to the nearest protective earth (ground) with a separate wire. -

Page 13: Maintenance
The Switch Analyzer is a field-test equipment and is constructed to withstand the handling it requires to fulfil its purposes, although the front panel is sensitive for scratches and other marks. The display is the most sensitive point of the SA5A, it will not tolerate harsh management. This should be considered during unpacking and handling of the unit. -
