For Your Safety *
The law relating to technical instruments (Gerätesicherheitsgesetz) of June
24th 1968 (Federal law gazette I, page 717), and the amended law of August
13th, 1979 (Federal law gazette I, page 1432) prescribe the following
instruction:
PAY ATTENTION TO THE OPERATING INSTRUCTIONS.
Each operation with this instrument presumes exact knowledge of and
adherence to these operating instructions.
The use of the instrument is for the described purposes only.
LIABILITY FOR FUNCTION AND/OR DAMAGES
The liability for the proper function of the instrument is irrevocably transferred
to the owner or user in case that the instrument has been serviced or
repaired by personnel not employed or authorized by the SEWERINService Team, or if the instrument is operated in a manner which does not
correspond to its intended use.
For this reason, always use original SEWERIN accessories for your ENA.
The Hermann Sewerin GmbH does not accept liability for any damages
resulting from non-observance of the above indications. The warranty and
liability conditions contained in our general terms of sale and delivery are not
extended by the above indications.
Subject to technical changes within the scope of further development.

1.0 Purpose and function
The output signal of a transmitter, e.g.:
- G1 generator
- W32/8
-W4
- Duophon
is directly fed into a shockproof mans-voltage socket via the ENA.
Lines which are electrically connected to the feed socket - such as
service lines - can be located with the receiver which goes with the
transmitter e.g. EL, ELW, E8 and E4B.
The ENA works like a high-pass filter. It ensures that the transmitter
signal is properly transmitted, at the same time preventing the
mains voltage from reaching the connection jacks for the transmitter.
2.0 Operation
The ENA must be connected to the shockproof mains-voltage
socket before the transmitter is connected and the status of the
light-emitting diodes noted in accordance with the notes (see
below).
The transmitter is connected to the two "generator" jacks on the
front of the ENA. When doing this, comply with the notes in section
4.0.

Page 9
3.0 Socket connection
On the front of the ENA there is a socket (item 1) which is directly
connected to the earthed wire. Two ligth-emitting diodes (LEDs)
indicate which of the socket contacts the phase is on.
NB: The status of the two light-emitting diodes must be noted
before a transmitter is connected.
3.1 One LED lights up
If the ENA is plugged into an intact shock-proof mains-voltage
socket, one of the two LEDs (TN-, TT-mains) must light up.
The light-emitting diode indicates on which socket contact the
phase is on. The transmitter can be connected safely and
successfully.
3.2 Both LEDs light up
If both light-emitting diodes light up, either the earthed wire is
missing or the circuit is an isolated one (IT circuit, fuse
disconnection, 2-phase circuit).
Important: Check the earthed wire.
The transmitter can be connected safely and successfully.

3.3 Neither LED lights up
If neither LED lights up, there is no mains voltage. The
preceding mains fuse should be checked.
If neither LED lights up and mains voltage is present, the
ENA is defective and it must be repaired.
4.0 Transmitter connector
On the front of the ENA there are two jacks, marked as
item 2. The transmitter is connected via instrument
leads.
Procedure:
- connect to a shockproof mains-voltage socket
- connect the transmitter to the “generator” jacks
- switch the transmitter on.
NB: The following sections regarding transmitter
power must be observed.
4.1 Transmitters up to 10 VA
Transmitters up to 10 VA in power, for example Duophon,
W4, can be directly connected: no special measures
need be taken.
8
Page 11
4.2 Transmitters above 10 VA
When connecting a powerful transmitter, for example W32/8, G1
generator, the maximum permissible transmission current (see
section 5.0) must not be exceeded. If it is, the internal protective
circuit is activated. The transmission current is substantially reduced, as a result of which line location can no longer be carried
out.
NB: connection to G1 generator: current < 100 mA
connection to W32/8 generator: apply the
adaption of max. 10 ; and not the power
stage 32 W.
Important: If the ENA is heavily overloaded it may suffer
lasting damage.
Ω
4.3 Line tracing
If the location of the end of the line which is to be traced is known,
it is of assistance to the line-tracing process to disconnect all
consumers, leaving only one (a lamp, for example) connected at
the end of the line which is to be traced. This ensures that the
transmission current flows to the end of the line.
If no LED lights up (section 3.3) and the mains fuse is inaccessible,
the transmitter can be connected to the earthed wire by means of
the earthing spike. To do this the earthing spike is connected to one
pole of the galvanic transmitter output and the other pole is
connected to the socket (item 1) of the ENA.
