WARNING! To protect the operator, the wire connected to the GND
terminal must be connected to earth ground. This unit should not be
operated without an adequate ground connection.
CAUTION! Use wire rated for currents drawn as specified on
equipment label.
WARNING! A device to disconnect the CW system from the energy
supply source is required. This switch or circuit breaker must be
close to the CW system, within easy reach of the operator, and
clearly labeled as the disconnection device for the CW system.
3.6 POWER OUT CONNECTIONS
1. Remove the protective cover from the terminal block.
2. A factory jumper has been added to connect NEUTRAL to GROUND.
If the front connector requires LINE and NEUTRAL to be reversed, move
this jumper to connect LINE to GROUND. See Figure 3-7 below. Most loads
require NEUTRAL to be grounded.
The factory jumper may be removed if the load has a GROUND or if LINE or
NEUTRAL voltages are held to less than 500 VRMS with respect to chassis.
3. Reinstall the protective cover on the terminal block.
WARNING! Verify that the load is set up to be LINE GROUNDED or
NEUTRAL GROUNDED. (Equipment with polarized plugs requires
NEUTRAL to be grounded.)
