Power Connections:
Power for the on-line analyzers is supplied by an integral universal (100-240V AC) power supply. The
appropriate AC line voltage is supplied with a standard power cord through a universal power entry
module. A standard computer type power cord (P/N A-1008 is required for the universal power entry
module.
Note: While the power entry module is universal, the heater is not. The heater must be configured to
the local power supply (100-110 or 220-240V AC) at time of order.
