For version with FO (fibre optics) refer to separate operation instructions
"AUMATIC ACExC 01.1 FO connection".
When working in potentially explosive areas, observe the
European Standards EN 60079-14 "Electrical Installations in
Hazardous Areas" and EN 60079-17 "Inspection and Mainte-
nance of Electrical Installations in Hazardous Areas".
Work on the electrical system or equipment must only be
carried out by a skilled electrician himself or by specially
instructed personnel under the control and supervision of
such an electrician and in accordance with the applicable
electrical engineering rules.
For the Ex-plug/socket connector (figure D-1), the electrical mains connec-
tion is made after removing the plug cover (50.0) at the EEx e terminals of
the terminal board (51.0). The flameproof compartment (type of protection
.
EEx d) remains hereby closed.
.
Check whether type of current, supply voltage and frequency correspond
to motor data (refer to name plate at motor).
.
Loosen bolts (50.01) (figure D-1) and remove plug cover.
Insert cable glands with "EEx e" approval and of size suit-
able for connecting cables. For the recommended cable
glands refer to appendix A, page 15.
(The enclosure protection stated on the name plate is only
.
ensured if suitable cable glands are used).
.
Seal cable entries which are not used with suitable plugs.
No more than max. 2 wires with the same cross section
. may be connected to one terminal.
Remove cable sheathing in a length of 120 – 140 mm.
.
Strip wires: Controls max. 8 mm, motor max. 12 mm.
For stranded wires use end-sleeves according to DIN 46228.
Connect bus cable. Refer to figures (D-4 or D-5).
The termination resistor for channel 1 is connected through linking the
terminals 31 – 33 and 32 – 34 (standard).
.
The termination resistor for channel 2 is connected through linking the
terminals 35 – 37 and 36 – 38 (component redundancy only).
.
Only connect the termination resistors if the actuator is the final station in
the Profibus segment.
Connect screen extensively to the cable glands. For the recommended
cable glands refer to appendix A, page 15.
If the actuator must be taken from the valve, e.g. for service purposes, it can
be separated from the mains without having to remove the wiring (figure
D-2). For that the screws (51.02) are removed and the plug/ socket
connector is pulled off. Plug cover (50.0) and terminal board (51.0) remain
together.
Flameproof enclosure! Before opening, ensure that there is
no explosive gas and no voltage.
A special parking frame (figure D-3) for protection against touching the bare
contacts and against environmental influences is available.
