ACH580 Installation, Operation and Maintenance Manual 99
ACH580 E-Clipse Bypass
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 Installation
instructions for the drive on page 40.
• X2 terminal block location is illustrated in the figures starting with Connection
diagrams – Vertical E-Clipse Bypass on page 91.
• X2 terminal data are provided in Basic control connections for E-Clipse HVAC
Default on page 108.
• 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.
Basic connections
The figure on page 108 shows the basic
control connections for use with the
E-Clipse Bypass HVAC Default macro.
These connections are described in the
following paragraphs.
In typical installations, only analog input
wires connect to the ACH580 terminal
block, with other control connections
made on the E-Clipse Bypass control
board.
Use wire ties to permanently affix control/
communications wiring to the hooked wire
race tie points provided, maintaining a
minimum 6 mm (1/4 in.) spacing from
power wiring.
