With an AC power module, AC power is supplied to the
FRM220
through a standard IEC C14 3-
prong receptacle, located on the rear of the module. Any national power cord with IEC C13 line plug
may be used to connect AC power to the power module. With a DC module, DC -48V is connected to
the terminal block located on the rear of the module, observing the proper polarity. The
FRM220
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.
