2.4 Communication ports
Comet EX RT provides 3 communication methods that can be used simultaneously:
◗ The COM port provides RS232 communications using MGE UPS SYSTEMS SHUT protocol. Compatible with most power
management software applications available into the enclosed Solution Pac CD-Rom.
◗ The output contact port is used for basic signaling or for protection of IT systems like IBM iSeries (formerly AS400) and
more.
◗ The slot is compatible with any MGE UPS SYSTEMS communication card (check www.mgeups.com web site for the
complete list of compatible cards).
Connection to the RS 232 communication port
1 - Connect the RS 232 23 communications
cable to the serial port on the computer.
23
2 - Connect the other end of the
communications cable 23 to the RS 232

communications port on the UPS.
The UPS can now communicate with various
MGE UPS SYSTEMS power management
application software. Please note that the
configuration software is included with
Personal Solution Pac for Windows.

2. Installation
2.7 Connections of input/output power cables
◗ This type of connection must be carried out by qualified electrical personnel.
◗ Before carrying out any connection, check that the battery circuit breaker 12 and that the upstream protection devices
(Normal and Bypass AC sources) are open ("0").
◗ Comet EX RT UPS always comes from factory with Normal and Bypass AC inputs already connected together, using a
bridge.
◗ Use included insulated ferrules with stranded wires.

Thermal characteristics
◗ The operating temperature is 0 to 40°C (8 hours at 45°C), however optimum operation is within the +20 to +25°C range.
◗ Battery backup time is adversely affected by high and low temperatures. It is significantly reduced at temperatures under
10°C. Above 25°C, battery service life is cut in half every 10°C. Above 40°C, battery manufacturers no longer guarantee
operation due to the risk of thermal runaway.
◗ Air enters through the front and exits through the back.
5.2 Glossary
Backup time
Time that the connected loads can operate on battery power.
Bypass AC source
ECO mode
Source supplying the bypass line. The load can be transferred to the bypass line if an overload
occurs on the UPS output, for maintenance or in the event of a malfunction.
Operating mode by which the load is supplied directly by the AC source if it is within the
tolerances defined by the user. This mode reduces the consumption of electrical power.
Load
Devices or systems connected to the UPS output.
Manual bypass
Rotary switch controlled by the user, used to connect the loads directly to the AC source.
Transfer of the load to the manual bypass enables UPS maintenance without interrupting the
supply of power to the connected loads.
Normal (double conversion) mode
The normal UPS operating mode in which the AC source supplies the UPS which in turn
supplies the connected loads (after electronic double conversion).
Normal AC source
Relay contacts
UPS
Normal source of power for the UPS.
Contacts supplying information to the user in the form of signals.
Uninterruptible Power Supply.
