2. FEATURES
2.3 CFR Rear Panel
1. AC Line Cord
The UPS is equipped with a standard, grounded AC line cord.
2. EXTERNAL BATTERY Connector
The connector accepts a standard plug from the EBP Series Battery Pack.
Extending backup time is as simple as plugging in the battery pack.
3. BATTERY Circuit Breaker
The battery breaker protects the DC circuit. When the UPS is not in service,
the breaker should be switched OFF to preserve the batteries in the UPS and in the
EBP Series Battery Pack, if installed (see section 4.1 “UPS Startup, Test, and
Shutdown”).
4. External Ground Lug (Single Point Ground)
The external ground lug provides a single point connection for optimum
grounding protection. Always refer to your local electrical codes for prescribed
grounding practices.
5. UPS Nameplate Label
The nameplate label contains valuable information relating to the UPS. Always
verify input voltage and frequency ( i.e., 120 VAC / 60 Hz) before use.
6. RS-232 Serial Connector (DE-9 Female Connector)*
The standard RS-232 serial interface allows for connection to a host computer /
dumb terminal for remote monitoring, control and calibration of the UPS. Use a
straight through serial cable to connect the UPS to the computer.
7. LAN Interface Connector (DE-9 Female Connector)
The LAN Interface connector provides dry contact status monitoring and output
shutdown capability on a DE-9 female connector. Used by basic UPS monitoring
software for orderly shutdown of computer networks.
8. External IID Connector (MMJ Connector)*
This connector is used for the optional desktop Intelligent Interface Device (IID)
for remote monitoring and control of the UPS (up to 2000 ft.).
NOTE: This port is disabled by the factory unless an internal IID is installed.
9. External Alarms Connector (RJ-45 Connector)
This provides dry contact closure alarm status on a RJ-45 (center keyed)
connector, indicating LINE FAIL and LOW BATTERY WARNING.
*NOTE: With the SID installed in the UPS, either the External IID port or
the RS-232 port can be activated. The factory default is set for RS-232
operation. With the internal IID option installed in the UPS
both por ts are
active.
