3. Electrical Connections
3.14. Supply to electronics and blower
Supply voltage: 3 x AC 380...480V, 50...60 Hz
Connected load: 300 VA (for maximum utilization of supply to electronics)
The mains connections for the supply to power and electronics sections are
strapped when the unit is delivered. No additional mains connection is thus
required for the electronics section.
If a separate supply for the electronics is needed, e.g., to store the TVD's
diagnostic signals with mains disconnection, then the links between power
and electronics section can be removed. Short-circuit protection need only be
provided in the control cabinet for the connecting cable, e.g., miniature circut-
breaker 3 VU 1300 -.MF00, 0,6 ... 1A, Siemens. Tap off electronics power
source between commutation chock and TVD.

The TVD 1.3 needs no additional mains connection for the blower. If drive
modules are used that need a mains connection for cooling, this is done on the
drive module next to the TVD 1.3. The mains connector for the blower supply
must be ordered separately. The order number for the socket is 219 118.
