To avoid mismatch between CT and VT connections the connectors are mechanically encoded and
cannot be inserted in the wrong location.

Auxiliary supply voltage input
The auxiliary voltage of the IED is connected to terminals X420-1 and X420-2/3 by one 0.5...2.5 mm
(AWG 20...13) wire or by two 0.5...1.0 mm
power supply module. The connector is delivered with the device.
The permitted auxiliary voltage range of the IED is marked on the identification sticker on the IED's
enclosure.

The BATTAMPL analog input gives the actual value of the supply voltage on the input terminals.
The two LEDs next to X420 indicate the following conditions:
•
Bat1 = input voltage (e.g. station battery) is within the expected range.
•
Rdy1 = output voltage of internal power supply is within the expected range (no IED internal
short circuit or overvoltage).

A single-phase reference VT shall always be connected to terminals X101:9-10,
regardless which system phase(s) it measures. If it does not measure L1 then the
application configuration should be adjusted for proper recording and display of the
signals (see Section).
