FIRST ENERGIZATION
After finishing the electrical installation according to the section
and before starting any
test with the SSW7000, check the following points:
DANGER!
Switch on the medium voltage only after the proper installation of the power arms.
1.
Verify whether the power, ground, motor and control connections are correct and tight.
2.
Verify whether the CSM voltage reading connections match the line voltage.
3.
Remove all the tools and odd materials from the SSW7000 panel.
4.
Verify whether the motor current and voltage match the SSW7000 model.
5.
Decouple the motor from the load.
6.
Switch on the electronics and execute the test mode to check the wiring with the panel door open.
7.
Close the doors of the SSW7000 panel.
8.
Measure the line voltage and verify whether it is within the allowed tolerances for the SSW7000 model and
for the motor.
9.
Carry out the tests described in section
7.1 - SSW7000 Operation Verification
, in order to check the proper
operation of the SSW7000.
DANGER!
Always disconnect the main supply before performing any connection inside the SSW7000 cabinet.
DANGER!
Disconnect the upstream voltage and connect the SSW7000 input to the ground at an adequate
point when any maintenance is performed at the SSW7000 disconnect switch.
7.1.
SSW7000 OPERATION VERIFICATION
DANGER!
In case the power supply of the low voltage circuits of the SSW7000 is performed by transformer
with primary connected to the medium voltage circuit, tests must not be carried out with the panel
door open. In this case, the test sequence described in item
7.1.1 - Test without Three-phase
must not be carried out and, additionally, maintenance procedures on the SSW7000 must
be carefully planned in order to prevent accidents.
The SSW7000 has a test mode that allows verifying if the cables of the panel are properly connected. The test
mode commands the selected signals and does not allow starting the motor.
There are two stages in the test mode. The first stage is executed with the three-phase supply off and with the
cabinet door open. The second stage of the test mode requires the three-phase supply switched on and a
connected motor. During this stage, the cabinet door must be closed.
The test can be performed either with medium voltage or with low voltage.
