Assembly and operating instructions Type 7E.56
5 A-active-energy meter, three-phase for current transformer, Fig. 1
Description
The 7E.56 is a compact electronic active power energy
meter for application in 3-phase power lines for current
transformer and neutral conductor. Depending on the
type, the well readable LCD display offers the reading
of additional values like instantaneous power, total or
per phase, as well as voltages and currents per phase.

Notes before connecting
1. Do not connect L1, L2 to L3 to N.
2. In order to avoid moisture in the meter due to
condensate build-up, acclimatise the meter at room
temperature for about half an hour before connecting.
Attention!
These devices must only be installed by a professional
electrician, otherwise there is the risk of fire or the risk
of an electric shock.
Operation of the LCD display
The operating menu is shown as a graph on the
figure 4. For setting the transducer value, the bridge
Z1-Z2 must be removed. After setting, this connection
must be restored.
Installation instructions
The three phase energy meter can be attached to a
35 mm rail (EN 60715TH35).
The meter can be used only in installation cabinets.
