NOTE: Do not use power tools to tighten these screws, use hand tools only. Refer to
page 17
for wire size and torque information.
1.
Power Input Connector: Remove one of the knockouts on the bottom left side of the drive. Route the
incoming power leads through the opening on the bottom left side of the drive and connect them to
the Power Board terminal block (#1 above).
• Use positions marked L1, L2, and
incoming power.
• Use positions marked L1, L2, L3, and
power.
2. J10, J11 EMC Jumper: If any line to ground measurements exceed specification,
these jumpers must be removed (four jumpers total; two on each one). Refer to
the NOTICE on the previous page and 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 (#3 in
the top image) positions marked
(U).
For drives that include an dV/dt filter, motor connections are made at the termi-
nal block (#3 at right) on the left side of the dV/dt filter. In this case, the termi-
nals are marked
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). Do not use power tools to tighten these screws, use hand tools only.
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 suitable for use on low voltage isolated circuits, and not recommended to
control critical systems (chemical dosing, etc.).
