NOTICE
Risk of flashover!
High voltages will be present in the terminal compartment. High voltages
can cause a flashover between conductors with different electric potential,
and between a conductor and earth.
Therefore, maintain a minimum clearance of 55 mm between a conductor
and the terminals of any other conductor, and between a conductor and
earth.
• Measure the insulation resistance of each cable before connecting it
and verify that the results are within the specification of the cable
manufacturer
• Leave the conductors unconnected at both ends until the
commissioning personnel has given permission.
• Connect the primary and secondary cables of the transformer, and
the motor cables to their corresponding busbars.
• Connect the primary cables of the transformer to the side of the
busbars where the arrows point to in
• Orientate the bolts for the transformer primary cables as shown in
6-7.
