SAFETY NOTES

PLEASE READ THIS AS WELL AS THE REST OF THIS MANUAL

FOR YOUR SAFETY.

There are dangerous voltages present in a UPS system. The
internal battery allows AC output with no external power con-

nected.

During installation and maintenance, the battery fuse should

be removed, and the 250VDC buss should be disengaged at
the external disconnect switch.

After installation and proper operation, keep the internal status
door  closed to protect personnel from dangerous internal

voltages.

Although this unit uses a sealed battery, explosive hydrogen
gas and/or corrosive acid may be generated if a system fault
takes place. 

 Keep sparks and flames well away from the UPS

system.

Use care when replacing the batteries.  Rough handling may
break the seal and cause an acid leak.

Eye protection is always recommended when working in an
industrial environment.
