2.3.3 Changing Voltage Settings
The 1936-R/2936-R-C Series can operate on several different supply
voltages. Before powering up the unit, check the facility AC voltage supply,
and select the appropriate setting according to the procedure below.
Use the following procedure to change the 1936-R/2936-R Series voltage
setting:
1. Ensure that the 1936-R/2936-R Series is turned OFF and disconnected
from the AC power source.
2. Disconnect the power cord from the AC power input connector on the
back of the 1936-R/2936-R Series.
3. Using a small screwdriver, insert and press down into the notch at the top
of the power entry module to pry the door open.
4. Carefully remove the voltage selector drum.
5. Rotate the voltage selector until the appropriate voltage will be viewed
through the voltage window.
CAUTION
Do not rotate the voltage selector drum while the drum is
inserted in its location. By doing so, you may bend the contacts
behind the drum, making the unit inoperable.
6. Reinsert the voltage selector drum.
7. If necessary, change the fuses according to the procedure found in the
Manual under ‘Replacing Fuses’.
CAUTION
Match the voltage setting to fuse sizing. Failure to do so may
result in damage to the power meter. Do not exceed 250VAC on
the line input.
CAUTION
There are no user-serviceable parts inside the power meter.
Work performed inside the power meter by persons not
Authorized by Newport may void the warranty.
