CHAPTER 2
INSTALLATION
2.2 Electrical Installation
With a built-in AC power chassis, AC power is supplied to the chassis through a standard IEC C14 3-
prong receptacle, located on the rear of the chassis. Any detachable nationally approved power
cord with IEC C13 line plug may be used to connect AC power to the chassis unit. With a built-in
DC power chassis, DC -48V is connected to the terminal block located on the rear of the chassis,
observing the proper polarity. The chassis should always be grounded through the protective
earth lead of the power cable in AC installations, or via the frame ground connection for DC
installations.
