A 19“ subrack of double width (84TE) is available for
integration into the motor drive ED of a MR on-load tap-
changer or any other switching cabinet application.
Installation is the same as previously described for the 19“
subrack in chapter 3.2. Please refer to the appendix for all
relevant dimensions.

Electrical Connection
The EPT202 must be connected as shown in the device-
specific connection diagrams in the appendix (see chap. 9.5
to 9.7). The individual connections will now be described in
more detail below. The numbering of the terminals is deviating
between the EPT202 for rail mounting and the EPT202 for
panel mounting or 19“ rack. The numbering for panel
mounting and 19“ rack is given in brackets in the following
describtion

WARNING
Make sure that the electrical connection of the EPT202
and particularly the grounding is performed carefully.
Otherwise there is a danger to life!
Do not switch on the supply voltage until the electrical
connection has been made correctly.

NOTE
The EPT202 was developed in accordance with applicable
EMC standards. To maintain the EMC characteristics, the
following points must be adhered to.
•Ensure that the EPT202 is properly grounded via the
grounding connection on the device.
•Use the shielded cables for the data and signal
connection from the EPT202 to other devices. Ground the
shield to the terminals provided for this purpose.

The EPT202 is equipped with a wide-range
input: 100 to 240 V AC or 100 to
353 V DC. Connect the supply voltage to
terminals 22 (42) L and 23 (41) N and the
grounding to terminal 21 (43) PE.

Sensor Inputs
The EPT202 can be operated with either a Pt100 or a 4-20mA
temperature sensor. In case, the ambient temperature is to be
recorded as well, a 4-20MA sensor must be used.
Measurement of the Top-Oil temperature is then achieved by
means of a Pt100 sensor.
