Chapter 2 Installation
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.
Either rear (preferred) or left 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 located 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
Figure 3 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 (6) sets of 3/8” hardware supplied.
• Install three (3) sets along the front door frame and three
(3) sets along the rear frame. Hardware along the rear
frame may 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 located 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.
