Cable connections for UPS WITH manual bypass
Note: the Manual Bypass Switch is OPTIONAL EQUIPMENT, not standard. If the customer desires a
Manual Bypass Switch it must be specifically ordered as a separate item.
This section describes cable connections for using the POWER+ PREMIUM SA 15 in 3-3
configuration using the rear-panel adapter that
HAS A MANUAL BYPASS SWITCH
.
The rear panel adaptor provides “single-feed” input, meaning that the bypass input is taken from the
rectifier input lines.
For 3-3 connections for the adapter
without
a manual bypass switch, see section
