Expansion Chassis Specifications
:$51,1*
Service must be performed by qualified personnel. All terminals, including the AC line and
analog inputs, must be disconnected prior to opening NetScan main unit or expansion
chassis casing. Internal voltage potentials exist which could cause bodily injury or death!

The Expansion Chassis contains no fuses; However, fuse failure in NetScan’s main chassis
indicates a possible problem with device circuitry. If a fuse blows, contact a qualified
service representative. Replacement fuses are to be installed by qualified service personnel
with the unit disconnected from the NetScan unit and with all other terminals disconnected.
If the line voltage selector is changed, then the fuse designated for that line voltage must be
used.
