The power connecter have the option of running four cables
instead of two, which allow the cable to be twice as long.
Cables with larger cross-section area that 1.5 mm2 may be
connected to the TT-3038G by use of the pigtail that is
supplied with the system (683088A; item 8).
By use of this pigtail, you may extend the cable length as
long as you keep the total source impedance < 250 mΩ and
cable inductance < 5µH.
The TT-3038G is equipped with an internal 10A thermal
circuit breaker; therefore no external fuse is necessary in
order to protect the unit. However, in order to avoid short
