C Strain Gauge Converter Installation Instructions
The Bul. 937 series' slip-off terminals significantly simplify
connection and construction of switching cabinets. They allow
quick and error-free exchange of the unit when service is
needed.
The terminals can be screwed on, are self-opening, and have
generous connection room for a wire diameter of up to 2.5 mm²
and coded plugs, so that leads cannot be confused.
The intrinsically safe field circuit is connected
to the
blue terminals 1 to 6 of the Strain
. auge Converters. This may be conducted
into the hazardous area using DIN EN
60079-14-compliant leads.
The non-intrinsically safe field circuit is
connected to the
black terminals 1 to 6 of
the Strain Gauge Converters.
In both cases you can connect:
• a half bridge (terminals 1, 3, 4, 5, 6)
• a full bridge (terminals 1 to 6)
