POWER CONNECTION
WARNING
Do not connect the M-207A power supply to any AC power other than the ones
listed in section 2.0.2.
The M-207A can operate on 9 different input line voltages and must be set up for
the one you are using. Use the following procedure to insure that the M-207A is
set-up for the correct AC power.
1. The M-207A is supplied with a 25’ power cord. One end has a connector on it
that plugs into the side of the M-207A. The wires on the other end are pig-
tailed (no connector). A suitable AC line connector, matching the input
power, must be supplied and installed by the user. Color coding of the
power cord is as follows:
Black ................. = Hot (high line side)
White ................. = Neutral (low line side)
Green/Yellow .... = Ground (protective earth ground)
NOTE
For additional ground reference there is a ground symbol silk-screened next to
the ground pin on the M-207A Input AC connector on the Input Panel.
