Operating Instructions

3. Brief description

The signal isolator serves to electrically insulate SINEAX SI 815-5

the 4...20 mA input circuit of a two-wire transmitter. It performs two

tasks at the same time. Firstly it provides electrical insulation and

secondly it conducts the power supply needed for measurement to

the two-wire transmitter without injecting into the circuit itself. Thus

the isolator does not require an power supply connection itself.

Some versions of the SINEAX SI 815-5 are designed for FSK com-

munication. They are used in conjunction with “intelligent” two-wire

transmitter which are capable of dialogue and operation according

to the FSK principle and the HART or user-speciﬁ c protocol.

The series also includes “intrinsically safe” versions [EEx ia] IIC with

an intrinsically safe measurement/supply circuit. These operate in

conjunction with intrinsically safe two-wire transmitters located in

explosion hazard areas.

are .observed

The device should only be handled by appropriately

trained personnel who are familiar with it and author-

ised to work in electrical installations.

Unauthorized repair or alteration of the unit invalidates

the warranty.

Indoor use statement!

6. Mounting

The SINEAX SI 815-5 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 version!Ex

6.1 Top-hat rail mounting

Simply clip the device onto the top-hat rail (EN 50 022) (see Fig. 4).

Fig. 4. Mounting on top-hat rails 35 x 15 or 35 x 7.5 mm.

6.2 Wall mounting

Drill 2 holes in the wall or panel as shown in the drilling pattern

(Fig. 5). Now secure the adapter (standard accessory) to the wall or

panel using two 5 mm diameter screws (Fig. 6). Clip the device onto

the adapter (Fig. 7).
