interfaces. For installation and setup of a MiniSlot card, please contact your Eaton representative.
To install wiring to the connections:
1. If not already installed, install the LAN drops.
2. Open the front door of the UPS.
3. To remove the MiniSlot cover plate, remove the 2 screws securing the plate.
4. To install the MiniSlot communication device, push it all the way in.
5. Secure the MiniSlot communication device with 2 screws.
6. Route and install the LAN and other cables to the appropriate MiniSlot cards.
7. For operator instructions, refer to the manual supplied with the MiniSlot card.
8. When all the wiring is completed, close the front door and secure it with the latch.

Obey the instructions mentioned earlier when you install the signal interface connections in a parallel
system. Signal inputs can be paralleled between the units, that is, the same contact can be used for
several units' signal input signaling. This concerns also the EPO signal.

The outputs of multiple 93PM G2 UPS systems can be connected in parallel. Up to eight units can be
paralleled. The UPS static bypass power rating needs to be identical among all the paralleled units.
However, paralleled UPS cabinets can be populated with a different number of UPM power modules.
The outputs are paralleled to increase the load capacity of the power system and for redundancy. The
system is paralleled for (N+1) redundancy, as long as there is always one or more UPS online than
required to support the load. The system is paralleled for capacity if all UPSs in a system are required to
support the load.
Communication between the UPSs is required for system metering and mode control. The system level
communication and control are accomplished using a Controller Area Network (CAN). A pull-chain signal
in each UPS, connected to the other UPSs in parallel and tied to the bypass status relay in each UPS, is
used for a secondary communication path. This arrangement ensures bypass control even if the CAN bus
is lost.

The input feed is defined as the power source connected to the UPS rectifier. The feed to all UPS's inputs
must be derived from the same source.

The bypass feed is defined as the power source connected to the UPS bypass. The feed to all UPS's
bypass must be derived from the same source. The shortest length of power wire from the source to the
UPS must be a minimum of 95% of the length of the longest wire.
