Alpha Technologies CFR Intelligent Interface Device - Manual (Page 36)

Remote Installation
The Intelligent Interface Device can also be used for remote applications
away from the UPS. The distance is dependent upon the gauge of wire used:
300 feet with standard telephone line cord; 1,000 feet with 24 gauge cable;
2,000 feet with 22 gauge cable. The remote Intelligent Interface Device sits on
a desktop and requires no additional retrofit. Simply plug its cable into the
back of the UPS. Note: If you are using two Intelligent Interface Devices, one
in the UPS and one as a remote unit, make sure that the unit used most often
is configured as master (see Section 3 "User Parameters").
1. Mount the Intelligent Interface Device in the desired location.
2. Connect the cable to the MMJ jack in the back of the Intelligent Interface
Device.
3. Connect the other end of the cable to the MMJ jack, labeled "I 2 D",
on the back of the UPS. Note: The UPS can continue to run while
plugging in the cable.
4. Test the unit for proper operation (see Section 3 "UPS Test").
5. Additional details regarding remote (serial and modem) operation can be
found in Section 5 ("Communication Interface Options").
Event Descriptions, continued
Equalize Charge Mode - Indicates that the battery charger was switched into the
equalize mode. This mode is automatically enabled after the UPS has operated
in the backup function, and serves to ensure that the batteries are optimized (all
at the same potential).
Float Charge Mode - This is the normal operating mode of the battery charger.
During LINE PRESENT operation, the batteries constantly receive a "Float"
charge voltage to ensure that backup power is available when required.
Service Codes (1-6) - These codes indicate a potential fault within the UPS. Call
Alpha Customer Support and report any Service Codes recorded in the EVENT
HISTORY log.
