7.7 Connecting the High-Voltage Transformer to the
Transformer Compact Station
Once the high-voltage transformer has been installed in the Transformer Compact Station, it must be connected to the
Transformer Compact Station. The connections on the Transformer Compact Station are prepared upon delivery.
The prepared terminals must be used exclusively for the connection between the low-voltage power switch and the
transformer.
7.7.1 Installing the Connection between the Low-Voltage Power Switch and the
High-Voltage Transformer

Requirements:
☐ The Transformer Compact Station must be mechanically anchored to the support surface
(see Section 6.3, page 16).
☐ The grounding of the high-voltage transformer must be connected (see Section 7.7.1, page 29).
Procedure:
1. Clean the contact surfaces (see Section 7.5, page 25).
2. Connect the cables coming from the low-voltage power switch to the low-voltage side of the high-voltage transformer
with screws, nuts and washers (torque: 37 Nm).
3. Ensure that the connections are correctly made.
