Safety instructions
All activities for the installation, commissioning, and main-
tenance of this current transformer must be performed by
qualified personnel with a knowledge of applicable safety
precautions. It is assumed that the reader of this document
has sufficient electro-technical knowledge to understand the
contents of this document.
General
The TQ split-core is a current transformer (CT) and can be
used only to measure electrical alternating currents. It is
suitable only for mounting on insulated primary conductors in
a weather-protected and dry location.
Explanation of symbols
This product is designed according to the EN
61010-2-032:2012 standards and therefore meets
the requirements of the Low Voltage Directive
2014/35/EU.
Do not apply around or remove from
UNINSULATED HAZARDOUS LIVE conductors,
which may render electric shock, electric burn, or
arc flash.
Read this Installation Guide before mounting the
product. Unprofessional work activities on
electrical installations may endanger the life and
health of human beings and livestock!
Under no circumstances may the secondary
circuit of the CT be opened while the CT is closed
and current is flowing in the primary circuit. High
voltages may appear on the secondary leads if
this circuit is left open.
RoHS Directive 2011/65/EU
ELEQ states that they use only qualified com-
ponents in their products from manufacturers
whose specifications meet or exceed the require-
ments of the European Directive for the
Restriction of use of certain Hazardous
Substances.
WEEE Directive 2012/19/EU
The 'crossed out wheeled bin' symbol indicates
that the equipment should not be disposed of as
unsorted municipal waste. Contact a qualified
recycler for disposal

Always avoid working on live parts of an installation!
Mounting instruction
No special tools are required to install a current transformer
(CT) of the TQ series. To correctly connect the CT to the
meter, please consult the meter's Operating Guide.
Assembly
Under no circumstances is the secondary circuit of the CT to
be opened while the CT is closed and current is flowing in the
primary circuit. High voltages may appear on the secondary
leads when this circuit is left open.
1. Ensure a safe working area during assembly, main-
tenance, and inspection of the CT. If necessary, discon-
nect the power of the primary circuit and make sure it
cannot be enabled unintentionally.
2. Find the power direction of the cable you want to
measure. It is recommended that you mount the P1 side
to the power source and the P2 side to the power con-
sumer. When installed like this, the arrow on the CT will
indicate the direction of the power flow.
3. Open the CT and mount it on the cable using cable ties.
Attention: Do not close the CT. High voltages may other-
wise appear on the open secondary leads!
Attention!
Do not touch the core surfaces by hand: Skin acid may
damage the core. Avoid dust on the core surfaces.
For mounting the TQ50
For the TQ50-E and the TQ50-L the top-part of the trans-
former can be removed entirely, which makes it even easier
to install the transformer. Attention: If the two parts are
separated, ensure that they are securely fixed together again.
If you mix different transformer parts, the measurement class
cannot be guaranteed.
4. Connect the secondary leads (S1, S2) to the low-
impedance current input of the measurement instrument
(e.g., an ammeter or current input of kWh-meter).
5. Close the CT only when you are sure that the secondary
leads are connected to the current input of the measure-
ment instrument. The CT is properly closed when you
hear a ‘click’.
6. Enable the primary circuit if necessary.
7. Check if the CT is mounted and closed properly. Check if
the secondary leads are connected properly and firmly.
Wiring Diagram
Maintenance and inspection
 Check whether the secondary leads are connected firmly.
 Check whether the CT is closed properly.
 Check whether the CT is mounted firmly.
 Remove heavy contamination on the casing. Contact with
moisture, especially with the core, must be avoided.
Attention!
Do not touch the core surfaces by hand: Skin acid may
damage the core.
Temporarily disconnecting the CT
The secondary leads of the CT must always be connected to
a low-impedance burden such as an ammeter. If, during
maintenance, no burden is available for connection, the
secondary leads of the CT (the two secondary terminals)
must be short-circuited.
Problem solving
E.g. unexpected values or incorrect values, reversed power:
 Check the meter's wiring, fuses, and settings in accordance
with the meter's Operating Guide.
 Check to ensure that the CT is mounted on the intended
cable in the correct direction.
 Check to ensure that the CT is closed properly.
 Check the value of the secondary burden (secondary leads
length-, diameter-, and meter-independent). See product /
data sheet for the maximum burden value.
 If the previous actions do not resolve the problem: Check
carefully to ensure that there is no dust or other con-
tamination present between the two parts of the core. If
contamination is present, clean the core surfaces with a
cleaning tissue and then apply an extremely thin layer of
acid-free petroleum jelly (Vaseline).
Attention!
Always follow the disassembling instructions when reversing
the CT.
Disassembly instruction
Tools are only required for removing the cable ties of the CT.
1. Ensure a safe working area during disassembling the CT.
If necessary, disconnect the power of the primary circuit
and make sure it cannot be enabled unintentionally.
2. Open the CT.
3. Disconnect the secondary leads from the measurement
instrument.
4. Remove the cable ties. Ensure that the insulation of the
primary conductor is not damaged when removing the
cable ties. Remove the CT.
5. If necessary, enable the primary circuit.
Recycling
When the product has reached ‘end of life’, it must be re-
cycled. Do not dispose of this product as unsorted municipal
waste. Contact a qualified recycler for disposal.
