Single-Phase Ac Motors; Connecting Ex Motors - Eaton PowerXL DC1 20 Series Installation Manual

2.11.6 Single-phase AC motors

2.11.7 Connecting Ex motors

It is strictly prohibited to use the DC1 variable frequency drives described in
this manual to run single-phase AC motors (induction motors), single-phase
asynchronous motors (capacitor motors), shaded-pole motors, etc.
There are other DC1 variable frequency drive models designed for use with
these motors: DC1-S1... and DC1-S2... with IP20 and IP66 degrees of
protection.

The following aspects must be taken into account when connecting
hazardous location motors:
• A DC1 variable frequency drive can be installed in an explosion-proof
enclosure within the hazardous location or in a control panel outside the
hazardous location.
• All applicable industry-specific and country-specific regulations for
hazardous locations (ATEX 100a) must be complied with.
• The specifications and instructions provided by the motor's
manufacturer with regard to operation with a variable frequency drive –
e.g., whether motor reactors (dV/dt limiting) or sine filters are required –
must be taken into account.
• Temperature sensors in the motor windings (thermistor, Thermo-Click)
must not be connected directly to the variable frequency drive, but
instead must be connected through a relay approved for the hazardous
location (e.g. EMT6).
