Installation and operating instructions Wilo-Yonos GIGA2.0-I/-D
Electrical connection
Cable requirements
Terminals are intended for rigid and flexible conductors with or without ferrules.
If flexible cables are used, wire end ferrules must be used.

Cable length ≥ 2 m: Use shielded cables.
**
When using ferrules, the maximum cross-section at the terminals of the communic-
ation interfaces is reduced to 0.25 ... 1 mm².
Table 10: Cable requirements
In order to comply with electromagnetic compatibility standards, the following cables
must always be shielded:
ƒ
Cable for EXT. OFF at digital inputs
ƒ
External control cable sensors at analogue inputs
ƒ
Differential pressure sensor (DPS) at analogue inputs, if installed on-site
ƒ
Twin-head pump cable with two single pumps in the Y-piece (bus communication)
ƒ
CIF module to the building automation (bus communication)
The shield is connected to the cable bushing on the electronic module. See Fig. 27.
Terminal connections
Terminal connections for all cable connections in the electronic module correspond to
push-in technology. They can be opened with a screwdriver type slot SFZ 1 –
0.6 x 0.6 mm.
Length of cable to strip
The stripping length of the cables for the terminal connection is 8.5 mm ... 9.5 mm.
