1 Safety First!

It is very important to follow all safety procedures when unpacking, installing and operating any sort of power equipment.

1.1. Warning Symbols

CAUTION: An indication that special care is required to prevent injury, equipment damage or misuse

WARNING: An indication of an electrical hazard that may cause serious personal injury or death, catastrophic equipment damage or site destruction.

1.2. General Precautions:

WARNING: Hazardous ac voltage levels are present inside the power system. Keep the ac input cover in place when the system is operational or energized.

WARNING: Hazardous energy levels are present on bare conductors in the -48Vdc distribution connection area of the plant. Accidental shorting of distribution conductors can cause arcing and high currents that can cause serious burns or other physical harm. It is recommended that:

Remove any jewelry, rings or watches while working on this equipment.

Use insulated wrenches, screwdrivers, cutters, pliers and other tools.

WARNING: Ensure that all of the dc and external ac circuit breakers are in the OFF position prior to connecting service to the power plant. Confirm that all voltages have been removed including any battery sources before proceeding.

Specific CAUTION and WARNING will be placed in manual where appropriate.
