7. ELECTRICAL CONNECTION
7.1. Cable connection to transmitter
All connection and installation operations shall be performed with disconnected supply volt-
age and other external voltages, if used.
Failure to provide proper connection of the transmitter may result in danger.
Risk of electric shock and/or ignition in potentially explosive atmospheres.
7.1.1. Connection of transmitters with PD-type connector
In order to properly connect the wires, remove the terminal block with its cover from the contact pins
and remove the block from the cover, undermining it with the end of the screwdriver inserted into the
slot provided for this purpose. Connect the wires to the cube as shown in the picture below.

If the sealing of the cables in the gland is ineffective (e.g. when single cables are con-
nected), the opening of the gland must be sealed with a flexible sealing compound to
achieve IP54 protection. It is advantageous to form the section of the signal cable lead-
ing to the cable gland in the form of a drip loop in order to prevent condensation from
running off towards the cable gland.
7.1.2. Cabling specification
Aplisens S.A. recommends using two-wire screened twisted pair cable. The recommended cable outer
diameter is 8-10 mm (PG-11 gland).
