measuring electrical alternating currents. The RM27 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-IEC 61010-1:2010 standards and therefore this
product meets the requirements of the Low Voltage
Directive 2014/35/EU.

Always avoid working on live parts of an installation.
Mounting instruction
Tools are only required connecting the primary cable running
through the Current Transformer. To connect the CT to the
meter correctly, please consult the installation guide of the
meter.
Assembly
Under no circumstances the secondary circuit of the CT may
be opened when the 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,
maintenance and inspection of the CT. Disconnect the
power of the primary circuit and make sure it can not be
enabled unintentionally.
2. Find the power direction of the cable you want to
measure. It is recommended to mount P1 side to power
source and P2 side to power consumer. If so the arrow on
the CT will indicate the direction of power flow.
3. Mount the CT on the cable. The RM27 can be mounted
stand-alone and clicked on each other. Optional: screw
mounting or mounting on a DIN-rail via the mounting clip
(411884).
4. Reinstall the primary conductor.
5. 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). For
more information about the secondary leads, please
consult the specifications table under ‘Technical
Specifications’.
6. Check if the CT is mounted properly.
Check if the secondary leads are connected properly and
firmly.
7. Enable the primary circuit.
Wiring Diagram
Accuracy
The CT may not meet its accuracy specification when the
secondary burden is to high. For example due to a secondary
cable which is too long or too thin.
Maintenance and inspection
Check whether the secondary leads are connected firmly.
Check whether the CT is mounted firmly.
Remove severe pollution on the casing.
Attention
Always avoid working on live parts of an installation.
Temporarily disconnecting the CT
The secondary leads of the CT always have to be connected
to a low impedance burden such as an ammeter. When,
during maintenance, no burden is available to connect to, the
secondary leads of the CT (the two secondary terminals)
must be short-circuited.
Problem solving
e.g. unexpected values, incorrectly values, reversed power
Check the settings of the meter by using the installation
guide of the meter.
Check whether the CT is mounted on the intended cable in
the right direction.
Check the value of the secondary burden (secondary leads
length/diameter and meter impendent). See product/data
sheet for the maximum burden value.
Attention
Always follow the disassembling instructions when reversing
the CT.
Disassembly instruction
Tools are only required disconnecting the primary cable
running through the RM27. To disconnect the meter from the
CT, please consult the installation guide of the meter.
1. Ensure a safe working area during disassembling the CT.
Disconnect the power of the primary circuit and make sure
it cannot be enabled unintentionally.
2. Dismount the CT from the primary conductor.
3. Disconnect the secondary leads from the measurement
instrument.
4. Reinstall the primary conductor.
5. Enable the primary circuit if is necessary.
