Electrical power may only be supplied once the earthing conductor is
connected and can be provided as a fixed cable if the thruster is
arranged stationary.
A pivoting arrangement requires a flexible cable. A minimum cable
cross section of 1.5 mm
connection terminals permit a maximum cable cross section of 2.5
mm 2 . When selecting the cables, the ambient conditions (e.g.
temperature, humidity) at the installation location must also be
considered.
The junction box is equipped with an M25 x 1.5 cable infeed (cable
diameters from 10 mm to 19 mm).
 The supply lines are always connected in accordance with the
switch diagrams on the inside of the junction box cover (⇒Junction
box and terminal diagram section).
 Only connection cables with a temperature approval of at least
110°C may be used.
Unless ordered differently, all ELDRO
star connection as delivered from the factory. If required, the
user can reconnect the bridges (⇒Junction box and terminal
diagram section) to also operate the motors in delta connection.
The motor's phase sequence and therefore its direction of
rotation do not matter.
thrusters with additional heating
NOTE
To control the additional heating, the operating company must
provide a temperature control unit that switches the heating on
below an ambient temperature of -20 °C and switches it off again
above -20 °C. The heating must not be switched on above -20 °C
due to the risk of overheating.
ELDRO ® thrusters with integrated additional heating (observe the
supply voltage) are connected in accordance with the terminal
diagrams located inside the junction box cover (⇒Junction box and
terminal diagram section). The cables for the motor's power supply
are guided via the M25 x 1.5 screw connection. The heating's power
supply is provided via the second M25 x 1.5 screw connection on the
junction box.
