MegaDySC System Installation Connections Checklist
• Connect the Automatic Bypass Switchboard ground bus to an earth
ground in accordance with the National Electrical Code and local codes.
• Connect the AC input (line) conductors to the terminals labeled "L1",
"L2" and "L3". The set is labeled "UTILITY INPUT". These terminals are
located left of the switchboard. See
Figure 6 .
• Connect the AC output (load) conductors to the terminals labeled "X1",
"X2" and "X3". The set is labeled "OUTPUT TO PROTECTED
LOADS". See
Figure 6 .
• For 4-wire models only: connect input and output Neutral (N)
conductors to the NEUTRAL bus bar. The input N connection is
required for proper operation of 4-wire models. Do not connect to the
NEUTRAL bus bar in 3-wire models.
• Check all electrical terminations for properly torqued connections.
See
Figure 6 .
• For i-Sense communications: connect either an analog telephone line to
RJ11 jack or Ethernet cable to RJ45 jack. The RJ11 and RJ45 jacks are
located in the upper switchboard compartment. They can be accessed
through a 1" conduit knockout in the top of the cabinet. See
Figure 6 and
Refer to i-Sense Voltage Monitor Communications on page 20 .
MegaDySC System Interconnections Checklist
(To be completed by factory-trained technician)
• Connect the Automatic Bypass (ABP) Switchboard-to-MegaDySC
ground cable to the ground bus in the MegaDySC.
• Connect line side cables from input circuit breaker (CBI) located in the
ABP Switchboard to the MegaDySC section bus bars labeled RH1-L1,
RH1-L2 and RH1-L3 respectively.
• Connect load side cables from the output circuit breaker (CBO) located in
the ABP Switchboard to the MegaDySC section bus bars labeled RH1-
X1, RH1-X2 and RH1-X3 respectively.
• Plug the control cable from the ABP Switchboard into the MegaDySC
cabinet.
