Electrical Connections - Camille Bauer SINEAX TI 807 Mode D'emploi

Drill 2 holes in the wall or panel as shown in the drilling pattern
(Fig. 6). Now secure the signal isolator to the wall or panel
using two 4 mm diameter screws.
Fig. 6. Drilling pattern.

8. Electrical connections

The electrical connections are made to screw terminals
which are easily accessible from the front of the signal
isolator (see Figs. 7 to 10) and can accommodate wire
2
gauges up to 2.5 mm .
Make sure that the cables are not live when
making the connections!
In the case of "intrinsically safe" explosion
proof versions [EEx ib ] IIC or [EEx ia] IIC, the
supplementary information given on the type
examination certification, the EN 60 079-14
and also local regulations applicable to
electrical installations in explosion hazard
areas must be taken into account.
Note that, ...
... the required electrical insulation and
transmission data agree with the data on
the nameplate of the SINEAX TI 807 (
input signals and
... in the case of a signal isolator with current
outputs 0...20 mA, the total resistance of the
external leads (receiver plus leads) does
not exceed the maximum burden of 1000 Ω
(non-Ex version) or 500 Ω (Ex version)! See
"Output signal" in Section "5. Technical
data"!
... in the case of a signal isolator with voltage
output 0...10 V, the external receiver
connected across the output has a
sufficiently high internal resistance Ri
relation to the SINEAX TI 807 output
impedance of 500 Ω! See "Output signal" in
Section "5. Technical data"!

... the input and output cables should be twisted
pairs and run as far as possible away from
heavy current cables!
Connect the input and output leads E1 ... E3 and A1 ... A3
according to Figures 7 to 10.
