Assembly

Assemble only during a process break. That is to say, the transmitter and the receiver
must have been assembled completely in conformity with the operating instructions
before the process can restart. Note that the Safety-Interface is not permitted for
operation in explosive atmospheres and so it must only ever be placed outside the
explosive atmospheres.
The PG cable screw is intended for cables with an external diameter of 8 to 11 mm;
other cables should not be used. The cables must be laid in such a way that they are
not at risk of damage.
The PG cable screw of the transmitter and the receiver must be carefully tightened in
such a way that the strain relief device can withstand the following test:
When subjected to stress with a value representing the diameter of the cable in mm
multiplied by 10, at the very least 100 N, the cable must not be pulled out of the PG
further than 6 mm at most in the course of 6 hours.
Do not open when the power is on.
Opening transmitter or receiver under a live tension may produce sparks and may lead
to explosion of gases or dust in the explosive atmospheres! Therefore, the housings
may only ever be opened after the power supply tension has been disconnected
outside the Ex-zone and safeguarded against reconnection. Wait for at least 60
seconds after switching off.
When the devices are fitted, the "Do not open under tension" warning must be easily
legible on the transmitter and receiver.
Warning:
Nicht unter Spannung öffnen!
Do not open under tension!
Ne pas ouvrir sous tension!
