Installation manual
Connect the meter in accordance with the installation diagram on the meter’s type label.
Depending on the configuration a fixed value will be displayed, or the display will change
between selected indications every 10 seconds.
It is possible to change the display reading manually by activating the left push button on
the meter. The available readings will depend on the meter’s configuration.
Security and installation guidelines
The meter is only to be used for measuring electrical energy and shall operate within the
specified values only.
The meter must be disconnected when working on it. It can be highly dangerous to touch the
meter parts when the meter is switched on.
Therefore, the relevant security fuse must be removed and kept in a place where it cannot be
inserted by unauthorized persons.
Current local standards, guidelines, regulations and instruction must be observed. Only
authorized personnel is permitted to install electricity meters.
Meters for indirect connection must be protected against short circuit by a security fuse in
accordance with the maximum current stated on the meter.

Installation manual
The phase current and the supply voltage indications indicate situations described below.
From the connection of the meter:
Indications L1, L2, L3
Indicate
On
Voltage is above minimum limit (160V)
Off
Voltage is below minimum limit (160 V)
Indications
Indicate
On
The load is above the minimum (0.6 W)
Off
The load is below minimum limit (0.6 W)
If the load exceeds the minimum limit and the meter is configured with this reading,
consumption will be indicated via the quadrant reading. The direction of the three phase
currents is indicated via the arrows above, respectively L1, L2 and L3.

Installation manual
With built-in radio
If the meter is supplied with integral radio for establishment of remote reading, the meter
automatically connects to a radio network. The integral radio is equipped with an internal
antenna. The radio signal strength can be read by means of a hand-held terminal. If the
radio signal is not sufficient, an external antenna must be connected. Please see current
documentation on available antennas.
Mounting a communication module in the meter may influence on radio communication,
please contact Kamstrup.
