Planning the electrical installation
44
Install the protective component as close to the inductive load as possible, not at the
relay output.
Residual current device (RCD) compatibility
ACSM1-04 drives are suitable to be used with residual current devices of Type B.
Other measures for protection in case of direct or indirect contact, such as
separation from the environment by double or reinforced insulation or isolation from
the supply system by a transformer, can also be applied.
Selecting the control cables
It is recommended that all control cables be shielded.
Double-shielded twisted pair cable is recommended for analogue signals. For pulse
encoder cabling, follow the instructions given by the encoder or motor manufacturer.
Use one individually-shielded pair for each signal. Do not use a common return for
different analogue signals.
