Delta M88H_121 ST, Quick Installation Manual

Page: 18 / 60

General information
The section describes the general technical characteristics of
the AC and DC terminal blocks. The special features which
apply to the installation of the inverter are explained in the fol-
lowing sections.
AC and DC terminal blocks are of the same type.
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.
