Section 4. INITIAL START-UP (“LOCAL” CONTROL)
4.1 PRE-POWER CHECKS
• Verify wires are properly connected
and no erroneous grounds exist.
• Remove all debris removed from the
GPD 503 enclosure. Check for loose
wire clippings.
• Verify all mechanical connections
inside the GPD 503 are tight.
• Verify motor is not connected to load.
• For 460V, 15HP (CT) and above only:
Verify that the GPD 503 power voltage
select connector, located at lower left
corner inside drive chassis (see Figure
4-1, A), is positioned correctly for
the input power line voltage. Voltage is
preset to 460V at the factory.
Reposition, if required, to match nominal
line voltage.
• For 575V, 15HP and above only: Verify
the GPD 503 power voltage select
connector (see Figure 4-1, B) is
positioned correctly for the input power
line voltage. Voltage is preset to
575/600V at the factory. Reposition if
required.
