210 ACH580 E-Clipse bypass and packaged drive user manual
Technical data
E-Clipse Bypass control unit connections (RBCU)
Control cable requirements for connections to the E-Clipse Bypass (RBCU) (X2) are the
same as those described for the ACH580 control panel (X1). Refer to the ACH580-01
Hardware Manual (3AXD50000044839) for additional information.
Bypass control unit connection specifications
WARNING! Relay coils generate noise spikes
in response to steps in applied power. To avoid
drive damage from such spikes, all AC relay
coils mounted across control panel inputs
require R-C snubbers, and all DC relay coils
mounted across control panel outputs require
diodes – see figure.
