6. Mounting
The SINEAX TI 807 can be mounted either on a top-hat rail or directly
onto a wall or mounting plate using the adapter (standard accessory).
Make sure that the ambient temperature stays within
the permissible limits:
–25 and +55 °C for standard instruments
–20 and +55 °C for instruments in Ex version!
6.1 Top-hat rail mounting
Simply clip the device onto the top-hat rail (EN 50 022) (see Fig. 3).
7. Electrical connections
The electrical connections are made to screw terminals which are easily
accessible from the front of the signal isolator (see Fig. 8 and 9) and can
accommodate wire gauges up to 2.5 mm2.
Make sure that the cables are not live when making
the connections!
In the case of “Intrinsically safe” [EEx ib] IIC or
[EEx ia] IIC explosionproof versions, the supple
mentary information given on the type examination
certification, the EN 60 079-14 and also local regula
tions applicable to electrical installations in explosion
hazard areas must be taken into account.
