UPS by yourself, installation must be under the supervision of authorized Delta engineers
or service personnel.
Before wiring or making any electrical connection, make sure the power supplied to the in-
put and output of the UPS is completely cut off.
When connecting the UPS to the utility AC power, you must install a protective device and
current must be equal to or larger than the current of the breaker shown in the table below,
and the coil voltage shall be from the input voltage. For installation of the protective device,
please refer to Figure 6-9~6-17.
