OPERATING CONDITIONS
The three-phase energy meter can be clipped to a 35 mm wide top hat rail. It must
only be installed in suitable installation cabinets.
Use the meter only in the German mains grid at 230V/400V and secure the device
against overload exceeding 80A.
The meter can be installed in any position.
INSTALLING THE TOP HAT RAIL METER
Notes for connecting the meter
The connection must only be established by a specialist! (e.g.
Klappt Meisterservice)
Ensure that line is powered down before connecting.
Do not connect phase L1, L2 or L3 to N.
To avoid moisture in the meter from condensate, give the meter
approx. half an hour time to adjust to room temperature before
connection.
The top hat rail meter VSM-102 records the electrical active consumption and trans-
mits the measured values to a connectable gateway via an RS485 interface.
