2 SAFETY REGULATIONS
IMPORTANT!
This instrument shall only be used by
authorized and educated personnel
.
It is the operator’s responsibility
to read and follow all operating and safety instructions for connecting and using this
instrument.
Always keep the below safety instructions in mind when using the instrument.
2.1 GENERAL SAFETY REGULATIONS.
•
Local safety regulations.
Always follow local safety regulations for work on high-voltage circuit breakers.
•
Ground connection.
Always connect the separate ground terminal (green/yellow) on
SA10A
to protective ground before any other
connections.
The
SA10A
unit can only be used in electrical system with a single ground.
If there is a High voltage ground and Low voltage ground make sure that there is no potential voltages difference
between these grounds. If a voltages difference exists between grounds, consult local safety regulations.
Check that the separate protective ground wire is in good condition before connection.
Make sure that the power socket for mains is a grounded outlet and that the power cable is in good condition before
connected the main power to the control unit
SA10A
.
•
Connections.
Before connecting the
SA10A
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.
Follow local safety regulations for work on high-voltage circuit breakers.
To avoid unintentional breaker operation!
Never do any work on a circuit breaker unless the control circuits of the breaker are disconnected from the
SA10A
control outputs or from any other remote control device.
All cables shall
first be connected to the
SA10A
before any connections to the test object.
Use of touch-protected connectors is required for personal safety.
Only use original cables for connection and make sure that the cables are in good conditions.
When the
SA10A
is connected to a wall socket, the socket
must be a grounded power outlet.
Note!
The inputs for coils “Uc” and motor “Um” are not fused!
Make sure that the output powers to these inputs are fused with maximum 32A.
Take care when working near bare connectors and bus bars. Contact with a conductor may cause an electrical shock.
Take special care at wet conditions.
