Environment and Enclosure
IMPORTANT
To avoid electrolytic corrosion on the external earth terminal, avoid spraying
moisture directly on the terminal. When used in wash-down environments,
apply a sealant or other corrosion inhibitor on the external ground terminal
to minimize any negative effects of galvanic or electro-chemical corrosion.
Ground connections should be inspected regularly.
IMPORTANT
To comply with the CE Low Voltage Directive (LVD), all connections to this
equipment must be powered from a source compliant with the following:
• Safety extra low voltage (SELV) Supply
• Protected extra low voltage (PELV) Supply
To comply with UL/C-UL requirements, this equipment must be powered
from a source compliant with the following:
• IEC 60950-1 Ed. 2.1, Clause 2.2 - SELV Circuits
IMPORTANT
This equipment is supplied as enclosed equipment. It should not require an
additional system enclosure when used in locations consistent with the
enclosure type ratings stated in the
section of this
publication. Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings, beyond what this
product provides, that are required to comply with certain product safety
certifications.
In addition to this publication, see the following:
• See also the following: NEMA 250 and IEC 60529, as applicable, for
explanations of the degrees of protection provided by enclosures.
IMPORTANT
This equipment is not intended for use in residential environments and may
not provide adequate protection to radio communication services in such
environments.
IMPORTANT
This equipment is intended for use in overvoltage Category III applications
(as defined in IEC 60664-1), at altitudes up to 2000 m (6562 ft) at the default
carrier frequency without derating. See PowerFlex® 755 On-Machine Drive
Specifications, publication
for altitude and derating information.
At the End of Life, this equipment should be collected separately from any
unsorted municipal waste.
