WARNING:
1. When the UPS sends the "shunt trip signal" to trip the breaker, it
requires 24Vdc/ 120W power to trip the breaker. If the power is below
120W or under 24Vdc, the tripping device may not work. The power
must be supplied from an isolated power source.
2. For installation of the power supply device, please contact Delta
customer service. Only authorized Delta engineers or service
personnel can perform the installation.
NOTE:
1. Suitable cable size of the function contact is 22 ~ 18 AWG.
2. Strip length of the cables should be 0.35" ~ 0.39" (9 ~ 10 mm).
3. The maximum length (recommended) of the cables connected to the
UPS is 33 ft (10 m).
4. The maximum length (recommended) of the cables connected to the
24Vdc power supply is 6.6 ft (2 m).
