3.5.2 Electrical connection
All terminals are rated for maximum 8 A.
Terminals 1, 2, 3, 5, 10 and 11 are for wire size 0.08
- 3.3 mm
2
(AWG 28-12); terminal 17 is for wire size
0.08 - 1.3 mm
2
(AWG 28-16). For voltage rating of
the individual terminals, see section 3.5 Electrical
connection .
For terminals 5 and 17, one 3-hole socket and one
8-hole socket are provided as accessories in the
package.
Terminals T1 and T2 are normally connected to 220-
240 VAC. See fig.
20 , pos. 1.
Terminal I3 may be connected to up to 600 VAC. See
fig.
20 , pos. 10 and the diagrams at the end of these
instructions.
4. Configuring the product
4.1 Potentiometer
Set the warning limit for stator insulation resistance
by means of a potentiometer. See fig.
20 (4). The
warning limit can be set between 1 and 10 MΩ. The
alarm limit is 1 MΩ.

4.2 DIP switch configuration
IO 113 must be configured for the connected pump
by means of the DIP switches. See fig.
20 (12).
Fig. 5 Shows that all DIP switches are in OFF
position
A configuration alarm will be given in the following
cases:
•
The configuration does not correspond to the
pump connected.
• The configuration fault is of safety-related
importance (see section
6.7 Approval ).
A configuration warning will be given if the
configuration fault is of function-related importance
(see section
6.7 Approval ).
The insulation between the cabinet in
which the module is fitted and the sensor
input terminals must have a dielectric
strength of 2210 VAC, or the cabinet must
be connected to earth.
External controllers connected to the IO
113 module via the RS-485 connection
must meet the requirements of IEC 60950-
1 or 61010-1 (USA: UL 60950-1).
If SM 113 is used in the installation,
connect a PTC sensor to IO 113.
