15.3.8 Power Supply

The Service Module Power Supply is a 24 V(dc) supply that provides power to the
Service Module Components and is only available in the 110/220 V(ac) Service
Module (IPN 930-202-G1) model. The Service Module Power Supply also supplies
power to the Analytical Module when attached. The 24 V(dc) power is not supplied
to the electrical connector at the top of the Service Module unless the Analytical
Module is connected. The 24 V(dc) Service Module (IPN 930-202-G3) utilizes the
external 24 V(dc) power supply to power the Service Module and Analytical
Module.
