Air Inlet Filter
A stainless steel grille incorporating an electrostatic particulate air
filter ensures cooling air drawn through the charger modules is free
of dust and particulate matter.
The filter assembly is fastened to the front of the housing with
thumbscrews.
The Maintenance section of this document covers the air filter
cleaning procedure.
AC Input Filter Board
FS3LU, FS5, FS9
The AC Filter Board distributes AC supply to the modules and
auxiliary power supply while providing protection to these
components from surges in the supply voltage.
AC input cables are terminated onto the AC filter board input
terminal via a five way terminal strip.
FS3LU only – Input Voltage Configuration
Configuration possible for single and three phase, 208V-480V
supplies. Configurable bus bars provide AC input type selection and
two headers allow either 240V or 480V connection to the auxiliary
power supply.
