■

Do not attach any cables or power cords to the power supply until it is installed in the carrier.

Do not power up the control unit until all of the modules and power equipment are installed.

Once they are installed, follow the procedures under “Powering Up the System” later in this chapter. Failure to

comply with these procedures can result in shock hazard or damage to the equipment.

■If a ring generator is specified in the system forms (Control Unit Diagram), install it in the power supply before putting the power supply in the carrier. The detailed procedure is provided in the section “Step 2a: Installing a Ring Generator,” later in this chapter.
