2. Grasp the isolating handle and push up until the switch is fully engaged.
Note: Depending on the position of the transfer switch and the RPTCS controller status the
transfer switch may automatically transfer as soon as it is connected.
RTS03-ABL (Load Break)
3. Grasp the bypass handle, and then push up on the handle until the bypass switch
is in the un-bypassed position.
RTS03-ABO (Overlapping)
4. Verify that the transfer switch position is the same source that the bypass switch
is bypassed by checking the switch position lights on the RPTCS controller or
the optional status indicator lights on the accessory panel.
Note: You can only bypass an overlapping bypass switch to the source that the transfer switch
is connected. Do not force the handle. There are solenoid interlocks that prevent bypass to
the source that the transfer switch is not connected.
5. Push the solenoid interlock pushbutton; while keeping the pushbutton depressed,
grasp the bypass handle and then push up on the handle until the bypass switch is
in the un-bypassed position
Internal Manual Operation
Open transition transfer switches can be manually operated by operating a crank handle on the
end of the operator(s).
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Only properly trained personnel should perform this procedure.
It is preferable to perform this procedure when the switch is de-
energized and locked and tagged out.
If this procedure is to be performed on a live switch follow all
NFPA 70E safety procedures and wear proper PPE.
Failure to follow these instructions will result in death or serious
injury.
Warning –Lethal voltages exist inside the bypass switch enclosure.
Only Trained Personnel should perform this procedure. Follow all NFPA
70E safety procedures and wear proper PPE.
Follow these instructions to manually operate the transfer switch:
1. Open the lower door
2. Verify the current position of the transfer switch by observing the position indicator
labels on the S1 and S2 cross arms (see figure 23). There is a mechanical interlock
on the transfer switch that prevents the switch from being connected to both sources
at the same time. On dual operator switches the closed source must be opened first,
and then the open source can be closed.
