Each cycle consists of an on-load and an off-loadperiod. The operation can be either periodic duty or non-periodic Local Control Panel makes up a complete interface forcontrol and Programming of the adjustable frequency control panel is detachable and can be installed up to 10ft [3 m] from the adjustable frequency Drive , , in a frontpanel by means of the installation kit significant significant for Mille Circular Mil, an American measuring unit forcable cross-sections.
