5.1 Gantry Cable Connections
Please refer to Figure 2-2 for complete system interconnect details.
1.) If using a rear cable entry box (B7850RC), install it now, before routing cables to gantry.
NOTICE Potential for equipment damage.
Observe correct polarity when connecting the high voltage DC power. Reversing these
leads will result in serious equipment damage. The HVDC positive conductors have red
insulation and are labeled “ONE.” The HVDC negative conductors have black insulation
and are labeled “TWO.” Lead “ONE” must be connected to lead “ONE,” and lead “TWO”
must be connected to lead “TWO.”
Observe correct phase rotation when connecting the axial motor power. Phases one,
two and three should be connected top to bottom.
2.) Install the cables to the gantry power pan. The power pan is located on the rear of the gantry
at its base. See Figure 2-18 and Figure 2-19 for connections.
Note: The gantry 120VAC cable may not fit under the gantry frame. Install this cable before gantry
placement—or remove the power plug—to route it under the gantry.
