CHAPTER OBJECTIVES
Chapter 3 provides the information needed to properly install
and wire the SMP-3 overload relay. All items must be read and
understood before the actual installation begins.
ATTENTION: The following information is
merely a guide for proper installation. The
National Electrical Code and any other governing
regional or local code will overrule this
information. The Allen-Bradley Company cannot
assume responsibility for the compliance or
proper installation of the SMP-3 overload relay or
associated equipment. A hazard of personal
injury and/or equipment damage exists if codes
are ignored during installation.
ATTENTION: The hard contact output includes
surge suppression circuitry that will allow voltage
to be present across terminals 30 and 40 when the
contact is open. The power supply must be
disconnected before performing any service.
ATTENTION: The green ground wire of the
SMP-3 overload relay must be connected to
earth ground. (See page 3-13 for fastening
requirements.)
ATTENTION: Outputs A and B are triac outputs
through which leakage current may flow in the
Off condition. This leakage current can be
hazardaous. The power supply must be
disconnected before performing any service.
