Supplying AC Power (Optional)
Connecting the Power Cord
Make sure that you perform the following steps before connecting the power. Failure to
do so may cause electrical shock or cause damage to the instrument.
WARNING
• Always use protective grounding to prevent electrical shock.
• Since the power cord supplied with the AC power supply kit has
a 3-prong grounded plug, the AC outlet to which the power cord
is to be connected must be a 3-slot grounded terminal.
• Before connecting the power cord, make sure that the power
supply voltage complies with the rated electrical power voltage
for the instrument.
• Before connecting the power cord, make sure that the
instrument's power switch is turned off.
• Never use an extension cord that does not have protective
grounding; otherwise, the protection feature will be negated.
• Do not use any AC power supply other than the power supply kit
(model 366969) from Omega.
Connecting the AC Power Supply
1
Make sure that the instrument's power switch is turned off.
2
Connect the optional AC adapter to the AC adapter jack.
