CAUTION:
If stranded wire is used to connect power to the pump, make
sure that all the individual strands enter the terminal block as
the wire is inserted. Peeled back strands can cause a short
circuit hazard at the pump terminal block connections.

4.7.2 I/O connections

CAUTION:
Connect the electronic drive only to Safety Extra Low Voltage
(SELV) circuits. The circuits provided for use with external
communications and control equipment are designed to pro-
vide isolation from neighboring hazardous circuits within the
drive. The communications and control circuits within the
ecocircXL drive are floating from ground and are classified as
SELV. They must be connected only to other SELV circuits in a
manner which maintains all the circuits within SELV limits and
prevents ground loops. Physical and electrical separation of
the communications and control circuits from non-SELV elec-
trical circuits must be maintained both within the inverter and
external to the inverters.
