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 national power cord with IEC C13 line plug may be used to connect AC power to the power module. 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.
