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.

CAUTION:
Connect the low voltage circuits of the electronic drive only
to Safety Extra Low Voltage (SELV) circuits. The circuits pro-
vided for use with external communications and control
equipment are designed to provide isolation from neighbor-
ing hazardous circuits within the drive. The communications
and control circuits within the ecocirc XL drive are floating
from ground and are classified as SELV. They must be con-
nected only to other SELV circuits in a manner which main-
tains all the circuits within the SELV limits and prevents
ground loops. Physical and electrical separation of the com-
munications and control circuits from non-SELV electrical cir-
cuits must be maintained both within the inverter and exter-
nal to the inverter.
