How to fit and setup the device

The controller may be connected only to 230VAC, 50 Hz public electric grids. Regulator must be
protected with a circuit breaker - recommended rating is B6A - and connected loads must also be
adequately protected! Installation may only be done when the facility’s main circuit breaker is
turned off!
Upon completion of the installation process make sure to check thoroughly the connection of the
regulator and the current sensing module. Also check connection of all pluggable terminal blocks,
where
NO
power grid voltage or voltage outside of tolerances specified in the chapter Technical
specifications may be connected!
NO
other than resistive (heating) loads may be connected to
power SSRs! Regular relays
CANNOT
be connected to SSR outputs! It is prohibited to connect
loads with higher than the maximum allowed nominal power! If you fail to observe these rules it
is almost guaranteed that you will damage the regulator and lose your warranty!
For the correct operation of the controller, it is absolutely necessary to ensure proper phasing of
the measured currents with the internal voltage detector. This can be done by selecting the
appropriate phase in the Input Settings tab. It is strongly recommended to connect the controller
so that the phase conductor fed to terminal L1 corresponds to the phase conductor wired
through the measuring transformer corresponding to the IL1 input, which will allow the
measurement to match the default settings of the controller (and therefore the same as required
for older models). The IL2 and IL3 current inputs can be connected arbitrarily, the respective
phases for these inputs must be set up correctly in the WATTconfig control software.
We strongly advise you to protect your loads connected to the power SSRs with fuses suitable for
protection of semiconductors, rather than regular circuit breakers. Please note that SSRs
damaged by overcurrent or short-circuit most likely cannot be claimed under warranty. Make
sure that solid state relays are correctly connected, as required by their user manual.
No electronic devices (various measuring and protective elements, such as sub-meters and
residual current circuit breakers) may be installed between the SSRs and the appliance, since
they may be damaged by impulse power! Always install these devices on the line between the
fuse and the solid-state relay where constant power is available.
If your facility is located in an area with higher risk of overvoltage spikes due to atmospheric
discharge (lightning), we strongly recommend fitting a suitable overvoltage/lightning protection
between the distribution box with the main energy meter and the current sensing module!
If any sensors are connected to the ANDI multi-purpose inputs, it is imperative to properly
configure their function, otherwise these and/or even the ILx inputs may not work properly!
The current sensing module supplied with the WATTrouter Mx controller is fully compatible with
the current sensing module supplied with older types of WATTrouter CWx, WATTrouter CWx
SSR, WATTrouter ECO, WATTrouter M and vice versa. The current sensing module installed with
these controllers can be used with the WATTrouter Mx controller (and vice versa).
However,
please note: The terminal marked GND for these older measuring modules must be connected to
the Y terminal of the Mx controller, not to the GND terminal!
If the regulator is constantly connected to PC via USB interface (mostly if long cable is used), we
strongly recommend using an USB isolator!
