38 TCS-JP-IA-en-10 Installation Manual
Requirements
☐ The high-voltage switchgear must be switched off.
☐ The low-voltage power switch must be switched off.
☐ All terminals must be connected in accordance with the manuals and the circuit diagram (see Section 7 "Electrical
Connection", page 20).
Procedure:
1. Check the cabling in the Transformer Compact Station (see Section 8.4, page 39).
2. Make sure the temperature settings on the contact thermometer of the high-voltage transformer are correct:
– Warning temperature: +100°C
5. Check the AC low voltage at the low-voltage power switch (see Section 8.4, page 39).
6. Switch on the low-voltage power switch.
7. Commission the inverter (see inverter documentation).
8.3 Checking the Cabling in the Transformer Compact Station
1. Ensure that all connections have been made in accordance with the circuit diagram.
2. Ensure that all connections are securely in place.
3. Check the equipotential bonding of the Transformer Compact Station to the mounting location. Connect if necessary.
3. Only a duly authorized person trained in electrical safety is allowed to connect the AC voltage of
the high-voltage transformer.
Have the AC voltage of the high-voltage transformer connected externally.
4. Only a duly authorized person is allowed to switch on the high-voltage switchgear.
Switch on the high-voltage switchgear (see documentation of the high-voltage switchgear).
