The EIB Delta-Meters are suitable for installation in distribution boards
or small enclosures, for wall mounting or panel mounting.They can be
snapped onto 35 mm mounting rails, according to DIN EN 50 022.
Connection: The electrical connection is carried out via screw terminals.
The terminal markings and insulation strip lengths are embossed in the
terminal area of the meter. (Wiring diagrams can be found in section 5.3).
The connecting screws should be tightened using the following torque:
Main terminal:
– Direct connected meter (M5 screw) 2.0 Nm
– Transformer rated meter (M4 screw) 1.2 Nm
When connecting aluminium conductors, the contact surfaces of the
conductors should be cleaned, brushed and greased. The connecting
terminals should be re-tightened after approx. 6 to 8 weeks.
Maintenance procedures can be simplified by using external terminal blocks
when connecting a transformer.
Fuse protection: The voltage circuit should be protected by a series-
connected,
miniature circuit-breaker, in order to prevent the meter from being
damaged in the event of a short circuit or overload.
– Direct connected meter max. 65 A (63 A)
– Transformer rated meter max. 6 A
Seal: To protect the EIB Delta-Meter from being tampered with after
installation and programming, it is possible to seal the device at four points.
