1. General descriptionIO 351 is a module for exchange of digital and ana-log signals between CU 351 and the remaining elec-trical system via GENIbus. IO 351 comes in the vari-ants A and B.IO 351 A is used for one to three Grundfos pumps with fixed speed.IO 351 B is used for one to six Grundfos pumps with fixed speed and/or pumps controlled by external fre-quency converters. The module can also be used as an input-output module for communication with mon-itoring equipment or another external equipment.

Prior to installation, read these installation and operating instructions. Installation and operation must comply with local regula-tions and accepted codes of good prac-tice.

Instructions with this symbol require spe-cial attention. If the instructions are not fol-lowed, there is a risk of personal injury.

If IO 351 is used in a manner not specified by the manufacturer, the protection pro-vided by IO 351 may be impaired.

Before installing the IO 351, make sure that the electricity supply has been switched off and that it cannot be acciden-tally switched on.

The terminals L and N as well as 76-81 and 82-89 may be connected to danger-ous contact voltage. External control volt-age from other groups may occur.

All wires to units outside the control panel must be of the type H05VV-F according to CENELEC HD21 (to avoid injury from touching wires).

3.1 LocationIO 351 is designed for indoor installation. For out-door installation the IO 351 must be mounted in a suitable panel.

3.2 Enclosure classIn order to reduce the external pollution level to max-imum 2, the IO 351 must be installed in a protecting environment with minimum IPX4 enclosure accord-ing to IEC 60529. The cabinet must be of a flame-retardant material.

3.3 TerminalsAll terminals are suitable for conductors of 0.5 to 2.5 mm² or AWG 20-13.

3.4 MountingIO 351 is prepared for mounting on a 35 mm DIN rail (EN 50022). Recommended height: 7.5 mm.Module dimensions and minimum clearance above and under the module, see 13. Dimensions.1. Fit the IO 351 by hooking the top on the DIN rail

and holding the bottom against the rail. 2. Push the locking tabs (pos. 1) into the module as

shown in fig. 5.3. Connect the conductors, see 8. Overview of

inputs and outputs.If the modules are mounted vertically, it is recom-mended to fit an end stop on the DIN rail below the lowest module.

Fig. 5 Mounting on DIN rail

3.5 EMC-correct installationIO 351 is usually mounted in a panel also containing a CU 351 and frequency converters, contactors and other power equipment. In order to ensure a faultless function, it is very important to install the electronic modules in an EMC-correct way:• Use screened cables for GENIbus. Connect the

screen to the cable clamp of the module forward of the terminals AA, YY and BB.

Fig. 6 Screen fixed with cable clamp

Any isolating plastic tape between screen and sheath must be removed before mounting the cable in the cable clamp.Signal conductors for digital and analog inputs and outputs should be screened, i.e. run the screen all the way to the IO 351 and connect it to frame with for instance a cable clamp. Alternatively, the signal conductors in the panel may be unscreened if the panel is divided into a power and a low-voltage area. Unscreened signal conduc-tors must not run in the power area, but exclusively in ducts in the low-voltage area. • Do not twist screen ends, as this will destroy the

screen effect at high frequencies. Use cable clamps.

• The module construction ensures a good electri-cal contact to the DIN rail. The DIN rail must therefore have a good connection to functional earth. If the module is mounted without a DIN rail by means of the four mounting holes (pos. 6), there must be a connection to functional earth through the fitting (pos. 3). See fig. 1 or 2.

• Use toothed washers and galvanically conducting mounting plates.

3.6 Allocation of address

1. Point the R100 against the IO 351 and press [OK]. See fig. 7.

2. Press [>] to go to the menu INSTALLATION.3. Press [∨] to get to Number (address).4. Set the address with [+] and [–].5. Point the R100 against the IO 351 and press

[OK].

The installation must incorporate a circuit breaker in order to switch off the mains supply. It must be close to the IO 351 and easily accessible for the operator. It must be marked as circuit breaker for IO 351. The circuit breaker must be according to IEC 60947-1 and IEC 60947-3.

10. ServiceIO 351 cannot be serviced. If the module is faulty, it must be replaced. See 12. Replacement of IO 351.

11. MaintenanceThe IO 351 is maintenance-free during normal use and operation. IO 351 must only be cleaned with a dust-free cloth.

12. Replacement of IO 3511. Switch off the power supply to the IO 351.2. Switch off the power supply to components with

external supply.3. Mark the individual conductors with the numbers

of the corresponding terminals.4. Disconnect all conductors.5. Pull the locking tabs free of the rail, see fig. 9.

The module can now be lifted off the rail.6. Mount the new IO 351, see 3.4.
