NOTE
If the external earthing conductor connection is used, the thruster's
pivoting ability and the surface temperature must be considered.
 The earthing conductor must always be connected before all other
cables.
There is one earthing conductor in the junction box (⇒Junction box
and terminal diagram section) and one in the immediate vicinity of the
junction box on the outside of the ELDRO
conductor must be installed on the ELDRO
with the applicable standards. The purpose of the earthing connector
is to reduce the contact voltage in the event of coil or insulation
damage to a safe amount and to switch the system off in conjunction
with monitoring equipment. This can only be achieved by measuring
the earthing conductor sufficiently, installing it properly and ensuring
that it is intact.
NOTE
Before connecting, check whether the mains voltage and the mains
frequency correspond to the specifications on the type plate.
Always keep the junction box clean.
Check that the sealing elements on the junction box are intact and
tight.
Always lock the junction box cover after connecting.
The M 25x 1.5 cable insert must be provided by the operating
company properly in accordance with the IP protection class
specified on the type plate.
Due to hydraulic laws, the motor's power consumption reduces
when the piston has reached the limit position. This prevents an
overload. A thermal protective switch is therefore not required. If
a motor protection switch is used to safeguard the ELDRO
thrusters despite this, we recommend adjusting the thermal
overcurrent trigger to 3 times the thruster current according to
the type plate.
If using a quick lowering switch (capacitors) and a motor protection
switch, the overcurrent trigger must be adjusted after consulting EMG
Automation GmbH.
