AC (120/220V) 16A Power Supply
Environment and Enclosure
ATTENTION
This equipment is intended for use in a Pollution
Degree 2 industrial environment, in overvoltage
!
Category II applications (as defined in IEC
publication 60664–1), at altitudes up to 2000
meters without derating.
This equipment is considered Group 1, Class A
industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring
electromagnetic compatibility in other
environments due to conducted as well as radiated
disturbance.
This equipment is supplied as "open type"
equipment. It must be mounted within an
enclosure that is suitably designed for those
specific environmental conditions that will be
present, and appropriately designed to prevent
personal injury resulting from accessibility to live
parts. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent
sections of this publication may contain additional
information regarding specific enclosure type
ratings that are required to comply with certain
product safety certifications.
See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations
of the degrees of protection provided by different
types of enclosures. Also, see the appropriate
sections in this publication, as well as the
Allen–Bradley publication 1770–4.1, ("Industrial
Automation Wiring and Grounding Guidelines"),
for additional installation requirements pertaining
to this equipment.
The 1771-P7 power supply can power one 1771-A1B, -A2B, -A3B,
-A3B1, or -A4B I/O chassis when used with any adapter module or
programmable controller (Mini-PLC-2/02 , Mini-PLC-2/05 ,
Mini-PLC-2/16 , Mini-PLC-2/17 , or PLC-5 family processor)
that does not have an internal power supply.
The power supply is not compatible with the
1771-A1, -A2, or -A4 I/O chassis.
