Connecting the meter
DANGER!
Risk of fatal injury in case of contact with live parts!
During installation or when replacing the meter, the wires connected to
the meter must be de-energised.
y Remove the corresponding pre-fuses and store them in a secure
location to ensure that no-one else can insert the pre-fuses again
without being noticed.
y If you use selective automatic circuit breakers for system discon-
nection, secure them to prevent them from being switched-on again
without being noticed.
y Before the installation of a meter, make sure that the consequences
of disconnecting the electrical system will not result in immediate
danger to the life or health of persons or cause any economic
damage.
y To avoid any immediate hazards or damage, take appropriate
measures to prevent malfunctions before disconnection of the
system.
y Do not use the internal disconnection relay as a load disconnecting
switch when disconnecting electrical systems.
y Use the specied screw-type terminals only for installation and
connection of the meter.
y Route the connection cables in the vicinity of the meter connection
terminals in such a way that they are not kinked or jammed when
the terminal cover is tted into place.
DANGER!
Risk of fatal injury due to arcing and electric shock!
The voltage taps in the meter are not fuse-protected, and are connect-
ed directly to the main voltage.
y External devices that are operated using the meter’s voltage taps
must be fuse-protected with a pre-fuse of ≤ 0.5 A in accordance with
the applicable technical regulations.
