W1 Ring Generator Switch Configuration (PSTU1 and PSTU2)
➤
On the PSTU1 or PSTU2, 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 PSTU1 or
PSTU2 experience ring trip.

RSTU2 Installation
1. Make sure the factory-installed SSTS or SSTU subunit is securely attached to the RSTU2
( Figure 9-29 and Figure 9-30 ).
2. Insert the RSTU2 (component side facing right) into the appropriate slot, and apply firm, even
pressure to ensure proper mating of connectors. RSTU2 must be installed per tables in Chapter
2 – DK40i Configuration .
3. After installing the RSTU2, gently pull the RSTU2 outward. If the connectors are properly
mated, a light resistance is felt.

WARNING! The shield on the back of the RSTU2 is designed to protect the installer from
potentially hazardous ring voltage. Do NOT remove this shield.
