2. FEATURES
2.3 CFR Rear Panel
AC INPUT Connector
The UPS is equipped with a standard, grounded AC power cord.
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.
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 EPS Series Battery Pack, if installed (see section 4.1 “UPS
Shutdown”).
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.
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.
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.
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.
External I 2 D Connector (MMJ Connector)*
This connector is used for the optional desktop Intelligent Interface
Device (I 2 D) for remote monitoring and control of the UPS (up to 2000 ft.).
NOTE: This port is disabled by the factory unless an internal I 2 D is installed.
External Alarms Connector (RJ-45 Connector)
This connector provides dry contact alarm status on a RJ-45 (center
keyed) connector. Contact closures indicate LINE FAIL and LOW BATTERY
WARNING.
*NOTE: With the SID installed in the UPS, either the External I 2 D port or
the RS-232 port can be activated. The factory default is set for RS-232
operation. With the internal I
2 D option installed in the UPS both ports are
active.
