Load Shed

(Forced Transfer to OFF)

Hazardous voltage.

Will cause severe injury or death.

Disconnect all power sources before

opening the enclosure.

DANGER

Servicing the transfer switch. Hazardous voltage can

cause severe injury or death.

Deenergize all power sources

before servicing. Turn off the main circuit breakers of all

transfer switch power sources and disable all generator sets

as follows: (1) Press the generator set off/reset button to shut

down the generator set. (2) Disconnect power to all battery

chargers. (3) Disconnect all battery cables, negative (--) leads

first. Reconnect negative (--) leads last when reconnecting the

battery cables after servicing. Follow these precautions to

prevent the starting of generator sets by an automatic transfer

switch, remote start/stop switch, or engine start command

from a remote computer. Before servicing any components

inside the enclosure: (1) Remove all jewelry. (2) Stand on a

dry, approved electrically insulated mat. (3) Test circuits with a

voltmeter to verify that they are deenergized.

The load shed (forced transfer to OFF) accessory must

be factory-installed.

The load shed accessory is

available only on programmed-transition transfer

switches. See Figure 4-22 for an illustration of the load

shed acessory.

The load shed function requires an external signal

(contact closure) to initiate transfer to the OFF position.

Connect the external contact to input #1 (if available) or

input #2 on connector TB1 on the main logic board. See

Figure 4-23. Use #12--24 AWG wire and tighten to

0.5 Nm (4.4 in. lb.).

Use the Input/Output setup menu or Kohler SiteTech

software to assign the connected input (Main Board

Input #1 or #2) to the forced transfer to off function. If the

external contact is connected to a different input

connection on an optional I/O module, assign the forced

transfer to off function to that input.
