Input Power
Each unit incorporates an INRUSH circuit. When the MAIN CIRCUIT SWITCH is turned on, the inrush circuit provides
pre-charging for the input capacitors. A relay in the Power Control Assembly (PCA) will turn on after the input capacitors
have charged to operating voltage (after approximately 5 seconds)
NOTE!
Damage to the PCA could occur if 253 VAC or higher is applied to the Primary Power Cable.
