Sync Control
An optional Sync Control maintains the critical load outputs of two separate single
module Powerware 9390/9390IT UPS systems in synchronization. This option
facilitates the uninterrupted transfer of the load from one load bus to another by
means of transfer switches. The Sync Control is housed in a wall‐mounted panel that
can be located between the UPS cabinets for easy wiring.
1.2.6
Optional X-Slot Cards
The optional X-Slot cards support several protocols, such as SNMP, HTTP, AS/400

and Modbus

. See Chapter 12, “Communication,” for additional information.

Remote Monitor Panel II
An optional Remote Monitor Panel II (RMP II) contains backlit status indicators and a
local horn, allowing you to monitor the operational status and alarm condition of the
UPS from virtually any location within your facility. This option is described further in
Chapter 10, “Using Features and Options.”
1.2.8
Relay Interface Module II
An optional Relay Interface Module II (RIM II) uses relay contact closures to indicate
the operating status and alarm condition of the UPS. This option is described further
in Chapter 10, “Using Features and Options.”
1.2.9
Supervisory Contact Module II
An optional Supervisory Contact Module II (SCM II) establishes an interface between
the UPS system equipment and the customer's monitor. This option is described
further in Chapter 10, “Using Features and Options.”
1.2.10
Energy Saver and High Alert Modes
Energy Saver mode allows the UPS to operate in Bypass mode. In this mode, the
UPS is operating on bypass, with the UPMs in standby, ready to automatically
transfer to Normal mode if a commercial electrical power brownout, blackout,
overvoltage, undervoltage, or out‐of‐tolerance frequency condition occurs.
In High Alert mode the unit transfers from Energy Saver mode to Normal mode
(inverter online) or if in Normal mode remains in Normal mode for a default time
period of one hour. The High Alert mode time period is configurable by an Eaton
Customer Service Engineer. High Alert mode allows the user to place the unit online
with full protection when outside conditions could cause a power disturbance. At the
completion of the time period, the unit defaults back to Energy Saver mode. If the
High Alert command is received during the time period, the timer will be restarted.
