AC cable
General information on the AC terminal block
The section describes the general technical characteristics of
the AC terminal blocks. The special features which apply to the
installation of the inverter are explained in the following sec-
tions.
The specifications in this section have been
defined by Phoenix Contact. Check if the techni-
cal specifications have changed before starting
installation work; see www.phoenixcontact.com.
NOTICE
Danger of a cable fire.
Bending and twisting causes damage to the
inner structure of the conductor, which leads to
punctiform increase in electrical resistance. This
can result in an overheating of the conductor
and destruction of the insulation.
► When bending and twisting cables or
conductors, always comply with the
manufacturer’s instructions.
