Standard Paralleling -F Option
With standard paralleling, up to three SynQor MPC units with identical model numbers can be
combined in various ways to achieve:
• Higher output power
• Higher output voltage
• Multiple output phases
• A balanced or unbalanced load for a 3-Phase AC input source
A configuration-specific CONFIGURATION cable determines each MPC unit’s role in a standard
parallel system. These CONFIGURATION cables are available from SynQor, and the proper part
number for any configuration is given in the pages that follow. These CONFIGURATION cables are
unique to –F option paralleling and cannot be used with –R option MPC units.
Configuration-specific OUTPUT and/or INPUT power cables are also required. These power
cables can be assembled by the user following the wiring diagrams shown below, or they can be
ordered from SynQor using the proper part number given in the pages that follow.
In a standard parallel system, the AC output will remain off until all MPC units are enabled. Each
unit must be enabled by actuating the front panel switch “on”, or by sending the appropriate
signal over the USER I/O cable. If any MPC unit is “off”, all of the MPC units will disable their
outputs. If any MPC unit cannot deliver output power because it cannot draw power from its
AC INPUT or its DC INPUT, or because there is an internal fault, then all of the MPC units will
disable their outputs.
