To adjust contrast, press and hold [ * ] and then press [Up Arrow] or [Down Arrow]. You may need to adjust the display contrast if the ACS 501 has been installed in a location with high ambient temperatures. The factory default setting is optimum for an ambient temperature between 59°F and 86°F (15°C and 30°C).
Ground Faults connected to the ground terminal. If the ACS 501 is connected to a system without system ground, the ground fault protection must be capable of starting at ground fault currents containing high frequency and DC components. The ACS 501 ground fault protection guards the variable frequency drive against ground faults occurring in the motor or the motor wiring.
If the cooling air contains dust, clean the cooling surfaces of the unit regularly using compressed air and a brush. If the ACS 501 is in a NEMA 1 enclosure, cover the vents to prevent the dust from entering the unit.
• DO NOT mount in direct sunlight. • DO NOT mount on surfaces with temperature above 104°F (40°C). • DO NOT allow the ambient temperature around the ACS 501 to exceed the ambient temperature as stated in Environment above. • Mount the ACS 501 vertically with the factory supplied conduit knockouts at the bottom.
