The following method is correspondingly applicable for all mono-bloc devices, but will be explained
here on the basis of the example of a 9 kW single-phase model and a 12 kW three-phase model
(both J Generation) (→
Installation example (Mono-bloc units), p.
Carry out the following steps to connect the power cord to the mono-bloc unit:
1. Open the mono-bloc unit (→
2. If there is a cover on the cable gland on the rear side of the cabinet (depends on model),
remove the cover before connecting the cable and re-assemble it afterwards.
If there is a cable sleeve (depends on model), cut the cable sleeve crosswise using a knife.
3. Guide the cable through the cable glands (2, 3) into the device.
4. Fix the cables using cable binders (5) and cable clamps/strain reliefs (8).
5. Connect the power cords 1 and 2 accordingly to power supply 1 and 2 (9, 10 or 11, 12),
according to the following installation example (see below) and the connection diagram
following it and take care to leave the earth conductor longer than the other cords in every
case. Also see that the cables do not come in contact with the pump (4) or other hot objects
such as the water pipes at any point, so that the insulation is not damaged.
6. Connect the other end of the power cord to the power grid via the disconnector which is
absolutely required in all cases.
7. Protect the individual power supply connections with a suitably sized fuse according to the
cable cross section and the maximum power consumption. Note that the contact clearance
between the poles must be a minimum of 3.0 mm.
