MegaDySC Dynamic Voltage Sag Corrector
System Clearance
The MegaDySC doors are hinged on the left, and clearance must be given to allow the door to swing open 90 degrees to the front of the enclosure.
Clearance for the Automatic Bypass switchboard must allow the front panels to swing (left side hinged) open 90 degrees to the front of its
enclosure.
Only front side access to the Automatic Bypass switchboard will be required during installation wiring and cabinet interconnect wiring.
System Mounting
The MegaDySC system is floor-mounted, and should be secured using the 0.63” diameter mounting holes provided along the bottom channels. The
MegaDySC section is provided with all necessary interconnect wiring to the Automatic Bypass switchboard section. Proper line-up is critical: The
MegaDySC section must be to the right of the Automatic Bypass section when viewed from the front of the system.
The DySC 400A Module MegaDySC section is shipped separately from the Automatic Bypass switchboard. The MegaDySC section must be
secured to the Automatic Bypass enclosure with the 3/8” hardware supplied. See
for fastening locations and hardware arrangement. The
optional ER enclosure is permanently connected to the MegaDySC section prior to shipment.
Figure 3 - System Mounting
Attach the MegaDySC section to the Automatic Bypass
switchboard using the six sets of 3/8” hardware supplied.
• Install three sets along the front door frame and three sets
along the rear frame. Hardware along the rear frame can be
omitted if rear access to the switchboard is not available: it
is necessary to remove the rear panel of the switchboard to
install the rear sets of hardware.
• Install bolts from the switchboard side and thread into the
weld nuts in the MegaDySC section enclosure.
• Each set consists of one 3/8-16 x 1.0” bolt, one 3/8 split lock
washer and one 3/8” flat washer, assembled as shown.
