Ex-separating chamber

To ensure sufficient "Air and creeping

distances" an Ex-separating chamber must

be mounted for the measuring data inputs in

case of Ex-applications. First of all loop the

lines through the Ex-separating chamber and

connect the lines. When using a multipoint

connector type "Screw terminals" the lower

wall on the Ex-separating chamber must be

broken away acc. to the notches. Fasten the

Ex-separating chamber with the lower screw.

Note the operating instruction of the carrier.

Coding

To exclude interchanging of the module card

VEGATOR 532 Ex, the multipoint connector of

the housing or the carrier rail is provided with

pins and the multiple plug of the module card

with holes (mechanical coding).

A function coding with fixed coded pin

ensures that not-Ex and Ex-module cards

are not interchanged.

An instrument coding with the coded pins

attached to the housing or module ensures

that the signal conditioning instruments are

not interchanged.

Insert the two coded pins into the determined

holes of the multipoint connector.

Transparent cover

To protect the instrument against

unauthorized adjustment, the front plate of

VEGATOR 532 Ex can be provided with a

lockable transparent cover.

Mounting single housing type 505 Ex

The socket can be either screwed directly to

the mounting plate or plugged on a carrier

rail (TS 35 x 7,5 acc. to EN 50 022 or TS 32

acc. to EN 50 035).

Connect the terminals of the basic plate acc.

to paragraph "3 Electrical connection". Furt-

her information on mounting is stated in the

operating instruction of the housing.

Protection with Ex-applications

For Ex-applications a protection of IP 20 must

be maintained. Therefore cover the gaps or

not coordinated modules from the front by

appropriate blind covers.
