Precautions
When working on or using this type of equipment, the following
precautions should be noted:
• The Galaxy Power System must be installed, serviced, and operated
only by skilled and qualified personnel who have the necessary
knowledge and practical experience with electrical equipment and
who understand the hazards that can arise when working on this type
of equipment.
• The Galaxy Power System may be powered by multiple ac inputs.
Make sure that the appropriate circuit protection device for each ac
input being serviced is disconnected before servicing the equipment.
• If batteries are connected to the Galaxy Power System, disconnecting
the ac alone will not necessarily remove power to the equipment.
Make sure the equipment is not also powered by the batteries or the
batteries are not connected to the output of the equipment.
• High leakage currents may be possible on this type of equipment.
Make sure the equipment is properly safety earth grounded before
connecting power.
• Hazardous energy and voltages are present in the Galaxy Power
System and on the interface cables that can shock or cause serious
injury. Exercise care and follow all safety warnings and practices
when servicing this equipment.
• Load cables must be sized in accordance with the cable lengths
shown in Table 2-A and Figure 2-1 to keep short circuit currents less
than the interrupt ratings of dc protectors in each panel (as shown in
Table 2-B).
