As a general rule, the following precautions must be taken:
• Terminals of the battery must be tight.
• Terminals must be clean and protected against rust.
• In case of solar panels, they must be clean, orientated
and well maintained.
This controller model has only one output with polarity
(pay attention to the connection), although all the pro-
tection elements and fuses meet the same quality stan-
dards.
The same power cable must be used for supplying power
to the outputs of controller. (In some cases, it is possible
to install two batteries).
12 Vdc power supply (batteries)
In battery-supplied controllers, pay special attention to
the quality of the connections made.
If an alternative manual control is installed, it is neces-
sary to take the precaution of having a second protection
fuse for the manual control of the system.
Originally, the output fuse is a 1,6 Amp fuse. This value
must never be exceeded under any circumstances.
Furthermore, the output supply has a 39V protection
varistor.

We recommend using only 2Amp fuses.
Never use fuses higher than 2Amp. In case it is fused
repeatedly, you should contact JIMTEN’s technical ser-
vices.
The power supply is protected by a fuse, varistors and a
network filter.
These varistors have the property of short circuiting when
the voltage is higher 220Vac, causing the fuse to blow.
They are placed between phases and phase to earth. If
we detect that the fuse is fused, this can be a result of
varistors operating. Therefore, we must check and repla-
ce them if necessary.
Moreover, this connection can also be used for extracting
the appropriate phase for the installation of a network
representation or of an alternative manual control, as
shown in this diagram.
The 1,6 Amp output fuse of the controller only acts on
the output common.
Never use the common phase as an output common sin-
ce, in this case, the protections that the controller in-
corporates (varistors, RC circuits and fuse) are disabled.
