Open the door and locate the power switch in the center of the upper rail. Be sure it is in
the OFF position.
CAUTION
The analyzer has been factory set to operate on either 110 or 220 VAC. Check
the voltage setting marked near the AC inlet. See Figure 5. The analyzer may be
damaged if operated on a different voltage than marked. Changing the operating
voltage requires the analyzer to be returned to the factory.
The power cord provides the protective earth connection. Ensure that the power
cord is plugged into a properly grounded outlet that conforms to national and
local electrical codes. Avoid damaging the power cord. Do not bend it
excessively, step on it, or place heavy objects on it. A damaged cord can be a
shock or fire hazard. Never use a power cord if it is damaged. Do not use a power
cord with inadequate ratings (less than 120 VAC, 10 Amps) or without a
protective earth wire
