Power Wiring Information
• Verify the correct supply voltage (115VAC or 230VAC) with the
nameplate affixed to your MPC. Ensure that your supply voltage
matches the MPC configuration.
• Wires should be routed within the enclosure in a manner that
maintains separation between low voltage and extra-low voltage
conductors.
• Applicable national and local electrical codes take precedence over
recommendations in the table below.
• A circuit breaker or fuse must be provided as noted below.
• Upon initial application of AC power, a current inrush will occur to
charge the DC bus capacitors. This is normal operation, and
breakers and other circuit protection devices should be sized
accordingly.

The MPC requires one connection to an external power source. It uses
this same connection to power its own supply, as well as the AC pump
motor. You must take all of these loads into consideration when sizing
