Safety Information
n The Symmetra
TM
contains an internal energy source. Hazardous voltage can be present even when discon-
nected from the utility power source.
n READ AND SAVE THIS USER’S MANUAL - This User's Manual provides safety, installation and operat-
ing instructions for optimal performance and service life from the Symmetra
TM
Power Array. A complete
list of technical support numbers are printed on the back cover. Record serial numbers on the back cover
before calling technical support.
n Before installing electrical connections -
Read, Study, and Understand the Electrical Installation Section of
this User Manual. All wiring connections must be made correctly by a qualified electrician.
n Where required, the electrician must attach the UPS warning tag to the input power distribution panel.
n Installation of the power and battery modules, and operation of the Symmetra
TM
to be performed by
personnel trained in electrical and mechanical hazards.
n Installation and replacement of the Main and Redundant Intelligence Modules (MIM & RIM) can be
performed by any untrained person.
n The protective earth conductor for the Symmetra
TM
carries the leakage current from the load devices
(computer equipment). Therefore, the size of the conductor must be at least as large as the wire required
by IEC 950. IEC 950 states the following nominal cross-sectional areas:
- 6 mm
2
for rated current between 33 & 40 A
- 10 mm
2
for rated current between 41 & 63 A
- 16 mm
2
for rated current between 64 & 80 A
- 25 mm
2
for rated current between 81 & 100 A
n The 120V, 7.2 Ah battery module constitutes a risk of electrical shock and an energy hazard. Before
replacing battery modules, remove conductive jewelry such as chains, wrist watches and rings. High short
circuit current through conductive materials could cause severe burns.
Indicates a hazard which, if not avoided, could result
in injury or death.
