Power connections – Box E-Clipse Bypass configurations
Line input connections
Connect the input power to the terminals at the bottom of the disconnect switch or
circuit breaker. Connect the equipment grounding conductor to the ground lug near
the input power connection point.
Motor connections
Connect the motor cables to the terminals at the bottom of the bypass section.
Connect the motor grounding conductor to the ground lug near the motor cable
terminal block connection point.
Note: Route cables through the cable guides on the left side of the enclosure. Use
separate conduits for input power and motor cables. Follow the guides to separate
the cables from each other.
WARNING! Check the motor and motor wiring insulation before connecting the
ACH580 to line power. Follow the procedure on page 16. Before proceeding with the
insulation resistance measurements, check that the ACH580 is disconnected from
incoming line power. Failure to disconnect line power could result in death or serious
injury.
Install the control wiring
Connect control wiring to terminal block X1 on the ACH580 control board and to
terminal block X2 on the E-Clipse Bypass control board. For more information on
these connections, refer to the following:
• X1 terminal block location and terminal data are defined in the
instructions for the drive on page 8.
• X2 terminal block location is illustrated in the figures starting with on page 86.
• X2 terminal data are provided in
Default
• Basic connections are described in the following paragraphs. Alternate
configurations using the E-Clipse Bypass macro are described in the ACH580
HVAC control program firmware manual.
• On Terminal Block X1 inside the ACH580, analog inputs and outputs and
additional digital input and relay output connections (AI1, AI2, AO1, AO2,
DI1...DI6 and RO1...RO6) are available for use.
Note: The E-Clipse Bypass control circuitry uses serial communications connections
(X1:29...X1:31) inside the ACH580. These connections are not available for any
other purpose and must not be reconfigured.
