Ground Connections
1.
Make sure a service entrance ground rod is properly installed and connected.
2. An input power ground wire from the supply panel must be connected to the drive.
3. A dedicated output ground wire from the drive must be connected to the motor. Motor and ground
wires must be bundled together.
Power Circuit and Motor Connections
NOTE:
Power connection terminals accept wire sizes from 6 to 20 AWG and
should be tightened to a torque of 15 in-lbs (1.7 Nm).
1.
Power Input Connector:
Route the 230VAC or 460VAC (depending on drive
model rating) power leads through the opening on the bottom left side of the
drive and connect them to the terminal block positions marked L1, L2, L3, and
(Ground).
2.
J10 EMC Jumper:
If any line to ground measurements exceed specification, this
jumper must be removed (both pins). Refer to
3.
Output to Motor:
Route the motor leads through the opening on the bottom
center of the drive (large opening) and connect them to the terminal block posi
-
tions marked
(Ground), Red (W), Yellow (V), and Black (U).
For drives that include an output filter, motor connections are made at the termi
-
nal block on the left side of the filter. In this case, the terminals are marked
(Ground), Red (U), Yellow (V), and Black (W). These terminals accept wire sizes
from 2 to 20 AWG, and can be tightened to 31 in-lbs (3.4 Nm).
NOTE:
Relay terminals accept wire sizes from 12 to 26 AWG and should be tightened to a torque of 3 in-lbs
(0.35 Nm).
4.
System Run Relay:
This connection activates whenever the system is actively pumping. Both normally-
open (NO) and normally-closed (NC) contacts are provided. The contacts are rated 5 A at 250 VAC/30
VDC for general purpose loads, or 2A at 250 VAC/30 VDC for inductive loads (i.e. relay).
5.
System Alarm Relay:
This connection activates whenever the system is faulted. Both normally-open
(NO) and normally-closed (NC) contacts are provided. The contacts are rated 5A at 250VAC/30VDC for
general purpose loads, or 2A at 250VAC/30VDC for inductive loads (i.e. relay).
NOTE:
These relays are not recommended to control critical systems (chemical dosing, etc.).
