Actuator controls AUMA MATIC AM/ AMExB/ AMExC
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".
The bus connection is realised via terminals (figure E-1) The terminal
compartment is designed for explosion protection "EEx e" (increased
.
safety). The controls AUMA MATIC (type of protection EEx d) remain closed.
.
Loosen bolts (1) (figure E-1) and remove terminal cover.
Insert cable glands with "EEx e" approval and of size suit-
able for connecting cables. For the recommended cable
glands refer to appendix D, page 57.
(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.

Suitable bus cables, see page 19.
Connect bus cable to channel 1 according to configuration of the termi-
nals (figure E-2).
.
The termination resistor for channel 1 is connected through linking the
terminals 1 – 2 and 3 – 4.
Only connect the termination resistors if the actuator is the final device in
the Modbus segment.
