1. SAFETY NOTICE
The smart energy meter of EM737 series does not require
special mechanical or electrical tools for its installation.
Mounting position (with any angle of tilt) has no effect on the
measurement functions of the meter.
Connecting of the meter must be made according to applicable
wiring diagram. Incorrect connection of the meter to the
electricity network causes major display problem and can
also causes serious damage to the meter.
Before starting meter operation, it must be ensured the local
conditions of the energy system are consistent with data on the
nameplate of the meter.
Preferably use for the connection of shielded cables. Make sure
that connecting cables are not damaged during installation of
the meter are not energized and free of non-mechanical stress.
Repairs when removing the cover of the meter, which is also
under tension can be made only by a qualified electrician who
is familiar with the associated risks.
Capacitors in the meter may still be charged even if the meter
is disconnected from all energy sources.
