Installationshinweise
Es ist darauf zu achten, dass alle stromführenden Leitun-
gen durch den Messstromwandler geführt werden.
Keine abgeschirmten Leitungen durch den Messstrom-
wandler führen.
Ein vorhandener Schutzleiter darf grundsätzlich nicht
durch den Wandler geführt werden!

Installation instructions
Make sure that all current-carrying leads are passed
through the measuring current transformer.
Do not pass shielded conductors through the measuring
current transformer.
As a general principle, the PE conductor must not be
passed through the measuring current transformer!
