3SU18 enclosures
10.1 Enclosures for actuating and signaling elements
SIRIUS ACT 3SU1 pushbuttons and signaling devices
224 System Manual, 08/2018, A5E03457306020A/RS-AK/010
The mounting position of the contact modules or LED modules is specified by the
combination of letters and numbers (permissible numbers: 1, 2, 3).
The lowest mounting position of an actuating or signaling element is always A and the
highest possible is F (for enclosures with 6 command points). This yields the following
highest possible mounting positions, depending on the number of command points in the
enclosure:
● Enclosures with 2 actuating or signaling elements ⇒ B
● Enclosures with 3 actuating or signaling elements ⇒ C
● Enclosures with 4 actuating or signaling elements ⇒ D
● Enclosures with 6 actuating or signaling elements ⇒ F
Contact modules can be mounted at the mounting positions 1 and/or 2 and/or 3, but LED
modules only at mounting position 3.

command points.
