9.0 Wiring Connections – PXL-250
Before performing any wiring or connection operations, ensure that controller power
is OFF. Serious damage to sensitive components on the controller may occur if wiring
changes are made while controller power is on.
The following instructions assume that J1, the RS-232 serial port, is pointed up. With
one exception (the RS-232 serial port), all connections to the PXL-250 controller are
made on the left side of the unit (see Figure 9-1). Specific information for making each
wiring connection is provided throughout the rest of Section 9.
NOTE: It is the responsibility of the installation organziation to have only technically
qualified personnel performing the installation.
