To Bypass the Transfer Switch
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
When in bypass mode and with the transfer switch racked in “not
isolated”, the “S1” and “S2” sources are still connected to the transfer
switch. Depending upon the status of the sources, the transfer switch
may still be electrically “live”. The transfer switch is not electrically
“dead” until it is “isolated”.
RTS03-ABL (Load Break)
1. Verify that the source that you are bypassing to is available by checking the
source available LED on the RPTCS controller or the optional status indicator
light on the accessory panel.
2. Grasp the bypass handle and slide it either right or left, then pull down on the
handle to bypass the switch to either the S1 or S2 source.
RTS03-ABO (Overlapping)
1. Verify that the source that you are bypassing to is available by checking the
source available lights light on the RPTCS controller or the optional status
indicator lights on the accessory panel.
2. Verify that the source that the transfer switch is connected by checking the
source 1 and 2 position LEDs 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.
3. Push the solenoid interlock pushbutton; while keeping the pushbutton depressed,
grasp the bypass handle and slide it either right or left, then pull down on the
handle to bypass the switch to either the S1 or S2 source.
