WARNING
Power supply selection will depend on the input power and load requirements of the
application. Load specifications for Series 90–70 modules are listed on page 9.
AC power supplies mount in the leftmost slot of a Series 90–70 rack. DC power
supplies can be mounted on the side of the rack or used as freestanding modules. The
DC power supplies require a power supply adapter, which installs in the power supply
slot and is connected to the power supply by a short cable.
