Configure Branch-circuit Protection
Branch-circuit protection for the line interface module is customer configurable.
By moving the CB2/CB3 wiring harness (P4) from one side of CB1 to the other,
you can change the module operation. To understand this option, see the
simplified block diagram and table below.

Follow these steps to move the CB2/CB3 wiring harness to the optional
configuration.
1.
Remove all input power from the line interface module.

Input VAC to CB2 and CB3 before CB1
(default configuration)
Closing CB1 removes 3-phase power to the device (servo
drive), however 24V DC (CB2) and 230V AC (CB3) auxiliary
circuits remain energized.
Input VAC to CB2 and CB3 after CB1
(optional configuration)
Closing CB1 removes all power to the line interface module.
(1) Applies to 2094-AL xx S and 2094-BL xx S (series B) line interface modules only.
IMPORTANT For the input VAC to CB2/CB3 before CB1 (default) configuration, no action is required.
ATTENTION: To avoid shock hazard or personal injury, verify that all power has
been removed before proceeding. This system may have multiple sources of
power. Multiple disconnect switches may be required to de-energize the
system.
