EPS 7000 Single and Shared Systems
3.3Main AC Input, (Mains 1) Connections
The connections to be made are the three phase and ground cables from the utility AC power source to the UPS module. Complete wiring instructions for your installation are provided on the installation drawings supplied with the equipment.
3.3.1 Single Module Bypass AC Input (Mains 2) Connections
The connections to be made are the three phase, ground, and optional neutral cables from the bypass AC input (mains 2) power source to the Q4S or MBP cabinet.
Where a single AC input source is used to supply both main AC input (mains 1) and bypass AC input (mains 2) connections, the bypass AC input is derived from the main AC input by a set of jumpers. These jumpers are installed at the factory.
3.3.2 Shared System Bypass AC Input (Mains 2) Connections
The bypass AC input source is connected to the SSC. The connections to be made are the three phases, optional neutral, and ground connections. Termination of these connections within the SSC are marked on the installation drawings supplied with the equipment.
If the maintenance bypass option is included, the maintenance bypass AC input source is connected to the MBP. The connections to be made are the three phases, optional neutral, and ground connections. Termination of these connections within the MBP are marked on the installation drawings supplied with the equipment.
Upstream Bypass circuit breaker must be provided with 24vdc shunt trip and aux contact and connect to the SSC terminal block provided for.
