MegaDySC Dynamic Voltage Sag Corrector

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 left of the switchboard. Se

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 Communication: connect either an analog telephone line to RJ11 jack or Ethernet cable to RJ45 jack. The RJ11 and RJ45 jacks 

are in the upper switchboard compartment. They can be accessed through a 
1" conduit knockout in the top of the cabinet.Se

Figure 6

 and Refer to

i-Sense Voltage Monitor Communication on page 12

.

MegaDySC System Interconnections Checklist

• Connect the Automatic Bypass (ABP) Switchboard-to-MegaDySC ground cable to the vertical strut in the MegaDySC cabinet at the 

location labeled with the ground symbol.

• Connect line side cables from input circuit breaker (CBI) 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) 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.

Communication

Remote Diagnostics and Remote Bypass

Relay dry contacts are available for remote monitoring of the state of the Bypass Circuit Breaker CBB and the Input Circuit Breaker CBI shunt-trip 
condition (See 

Figure 7

). In addition, a customer-supplied relay can be used to remotely command a Seamless Bypass operation, as described in 

Publication 1608M-UM005. These functions are available from terminal block TB1 in the upper compartment of the bypass switchboard. See 

Figure 9

 and 

Figure 6

 for recommended conduit entry location.
