Communications
i-Sense Voltage Monitor An i-Sense voltage monitor is mounted on the Automatic Bypass Switchboard to
continuously monitor the 3-phase input and output voltages of the MegaDySC
system. The i-Sense is wired in parallel with the bypass circuit breaker CBB. For
3-wire systems, the i-Sense monitors Line-Line voltages. For 4-wire systems, it
monitors Line-Neutral voltages.
The i-Sense requires communication via the Internet to access the recorded
voltage data. Two options for communication are provided: Ethernet (RJ45
port) or PSTN (analog only) telephone line (RJ11 port). These communications
ports are extended to the top of the Bypass Switchboard for permanent wiring
installation. The ports are labeled as shown in
Figure 5 .
Refer to the i-Sense User Manual (publication 1608S-UM001A-EN-P) for
registration, configuration, and operation instructions.

Remote Diagnostics—TB1
Relay Contacts TB1 Schematic Diagram and Contact Ratings
The Automatic Bypass Switchboard contains relay dry contacts, available at
terminal block TB1, for remote monitoring of the state of the Bypass Circuit
Breaker and certain status conditions in the MegaDySC. Refer to
Figure 6 .
TB1 is located in a compartment at the top of the right switchboard section.
The terminal block is labeled: TB1 CUSTOMER CONTACTS.

ATTENTION: Remove power from the MegaDySC system prior to connecting
any alarm notification device. Access to the terminal contacts risks exposure to
120 VAC potential. Accidental operation of the automatic bypass circuit is
possible.
