3. SUDC Sequence Of Operation

SUDC208V42P30M, SUDC208V42P40M, SUDC208V42P60M & SUDC208V84P60M
The 30M/40M/60M suffix in the distribution center part number indicates an integral 3 breaker maintenance bypass in the
bottom of the cabinet. The feature enables make-before-break isolation of the UPS from the critical load for maintenance of
the UPS.
The drawing illustrates power flow and sequence of operation of the bypass
switch. It is important to follow the procedure correctly to avoid damaging the
UPS or dropping the critical load.
1 Put the UPS into bypass by turning off the inverter (press the red button
then turn the manual rotary switch to bypass on the back of the UPS)
2 Using the Key, retract SW2 bolt and close SW2
3 Using key, retract bolt and open SW3

The UPS is now in bypass. To return to normal operation, reverse the process.
Wiring
The drawing below shows bypass utility input
and UPS isolation output
prewired to the distribution panel, which reduces installation time. Use
the attached table as a wiring guideline subject to NEC and local codes.
Flexible cable and conduit is recommended for ease of installation.
Access panels are located on the side and rear of the bypass enclosure
for access to termination points.
