3.6.1
CONNECTING AC/DC POWER CABLE
This section will explain how to make and connect your power cable to power the SOLYS2.
Important Rotation lap
Please understand that by applying power to the SOLYS 2 it will trigger a routine initialization
procedure.
During this procedure it will check for GPS signal, make a 540° rotation and stops in home position for
a complete minute.
Therefore it’s advisable to actually apply the power while checking chapter 3.6.4
SOLYS 2 is supplied with 2 waterproof power connectors, for both AC and DC. These connectors are in
accordance with safety regulations for outdoor usage. The voltage drop over the cable should not cause the
supplied voltage to be out of specifications.
Both the AC and DC connector are suitable for cable diameters between 6 and 12 mm. For 6 – 9 mm
and 9 – 12 mm different sealing rings are used.
The AC connector is female type Hirschmann CA 3 LD connector.
The DC connector is a male type Hirschmann CA 3 LS connector.
