1Getting to know LOGO!
What is LOGO! ? –
LOGO! is the new universal logic module from Siemens.
With dimensions of 72 x 90 x 55 mm, LOGO! provides:
SControl functions
SAn operating and display unit
SA power supply
S6 inputs and 4 outputs
SAn interface for program modules and a PC cable
SReady-to-use basic functions that are often required in practice, such as
functions for on- and off-delays and pulse relays
SA time switch/clock (LOGO! 230RC)

You can use LOGO! for domestic and installation engineering tasks (e.g.
stairway lighting, external lighting, sun blinds, shutters or shop window
lighting) and for mechanical and apparatus engineering (e.g. gate control
systems, ventilation systems or rainwater pumps).

2Installing and wiring LOGO!
You install LOGO! in a distribution box or cabinet, ensuring that the con-
nectors are covered. If they are not, there is a danger of touching live
parts.
LOGO! must be installed and wired by a trained technician who knows
and complies with both the universally applicable engineering rules and
the regulations and standards that apply in specific cases.
Dimensions
The dimensions of LOGO! comply with the DIN 43880 standard for the
dimensions of installation equipment.
LOGO! must be snapped onto a DIN rail with a width of 35 mm
(DIN EN 50022).
LOGO! is 72 mm wide, which corresponds to the size of 4 modules.

2.1 Installing/deinstallingLOGO!
You install LOGO! on a DIN rail as follows:
1. Place LOGO! on the rail.
2. Swivel it. The snap catch on the back of LOGO! must engage.
Depending on the type of DIN rail used, the snapping mechanism may be
a bit stiff. If it is too stiff and LOGO! will not snap on, you can pull the
snap catch down a little, as you do when deinstalling LOGO! as described
below.
You deinstall LOGO! as follows:
1. Insert a screwdriver in the hole shown in the picture at the lower end of
the snap catch, and pull the snap catch downward.
