On the PSTU, ensure the W1 switch is set to the "H" (190V P-P) position for initial
installation. The "L" (130V P-P) position is used if devices connected to the PSTU2
experience ring trip.
Only the RSTU3 will support this feature.
Make sure the factory-installed SSTS or SSTU subunit is securely attached to the
PSTU/RSTU (Figure 3-17
WARNING! The shield on the back of the RSTU is designed to protect
the installer from potentially hazardous ring voltage. Do
NOT remove this shield.
Insert the PSTU/RSTU3 (component side facing right) into the appropriate slot, and
apply firm, even pressure to ensure proper mating of connectors.
After installing the PSTU/RSTU, gently pull the PSTU/RSTU outward. If the
connectors are properly mated, a light resistance is felt.
