The Eaton 93E UPS has two standard, factory-installed Mini-Slot communication bays. The UPS is compatible
with the following Mini-Slot cards (see Figure 46):
Network Cards:
NOTE Only one of the four following network cards can be used for network connectivity at
one time.
• Eaton Gigabit Network Card (NETWORK-M2) – Eaton’s latest UPS connectivity device that delivers better
speed and cybersecurity, the Gigabit Network Card improves business continuity in two ways: by
providing warnings of pending issues to administrators and helping to perform orderly shutdown of servers
and storage.
• Eaton Industrial Gateway Card (INDGW-M2) – combines the features of an SNMP agent, HTTP/web server
and a Modbus card to facilitate remote monitoring of your UPS system through any Building Management
System. Enjoy the freedom to customize and schedule actions, like shutdown protocols and load
shedding, and receive immediate notifications during power events, without having to be onsite.
• Modbus-MS Card (MODBUS-MS) – provides remote monitoring through a Web browser interface, e-mail,
and a network management system (NMS) using SNMP and connects to a twisted-pair Ethernet (10/
100BaseT) network. The card also provides direct integration of UPS information (meters and status) to a
Building Management System (BMS) using the Modbus RTU protocol.
• Network Management Card (NETWORK-MS) – provides remote monitoring through a Web browser
interface, e-mail, and a network management system (NMS) using SNMP and connects to a twisted-pair
Ethernet (10/100BaseT) network.
Relay Cards:
• Relay Card-MS (RELAY-MS) – contains two types of interfaces via a DB9 connector are available with this
card. Dry contact mode provides a simple way to transmit UPS information to an alarm system, PLC, or
computer system via dry relay contacts. Normal, Bypass, Battery, and Alarm modes can be monitored. See
Table 21 for default triggers. RS232 mode provides an RS232 interface for connection to a PC or to a UPS
Control display unit. Jumpers are used to select the interface (contacts or RS232).
• Industrial Relay Card-Minislot (INDRELAY-MS) – can be used to indicate the operating status of the UPS
system using the customer's monitoring equipment. The Industrial Relay Card uses five isolated normally-
open or normally-closed dry relay contacts to indicate the UPS status. Normal, Bypass, Battery, and Alarm
modes can be monitored. See Table 21 for default triggers. The contact ratings and wire range are listed in
the IRC-MS installation guide. One input can be activated by a switch or dry contact. The voltage source is
provided by the card, no external voltage source is needed.
LAN and telephone drops for use with Mini-Slot connectivity cards must be supplied by facility planners or the
customer.
NOTE For installation, setup, and operation of a Mini-Slot card, refer to the instructions
supplied with the Mini-Slot card. For additional assistance, contact an Eaton service
representative.
