Introduction

 

This document contains information necessary to successfully install your hardware.

 

NOTE

 

Only used with analog connector on KPCI-3108/7 boards.

 

WARNING

 

The STP-36CJC is not intended for use in circuits carrying voltages in excess of 
30V RMS, 42.4V peak, or 60VDC.

 

General definitions

 

The types of product users are:

 

Responsible body

 

 is the individual or group responsible for the use and maintenance of equipment, and for ensuring that oper-

ators are adequately trained.

 

Operators

 

 use the product for its intended function. They must be trained in electrical safety procedures and proper use of the

instrument. They must be protected from electric shock and contact with hazardous live circuits.

 

Maintenance personnel

 

 perform routine procedures on the product to keep it operating, for example, setting the line voltage

or replacing consumable materials. Maintenance procedures are described in the manual. The procedures explicitly state if the
operator may perform them. Otherwise, they should be performed only by service personnel.

 

Service personnel

 

 are trained to work on live circuits, and perform safe installations and repairs of products. Only properly

trained service personnel may perform installation and service procedures.

The 

 

 

 

symbol on an instrument indicates that the user should refer to the operating instructions located in the manual.

The 

 symbol on an instrument shows that it can source or measure 1000 volts or more, including the combined effect of

normal and common mode voltages. Use standard safety precautions to avoid personal contact with these voltages.

The 

 

WARNING

 

 heading in a manual explains dangers that might result in personal injury or death. Always read the associated

information very carefully before performing the indicated procedure.

The 

 

CAUTION

 

 heading in a manual explains hazards that could damage the instrument. Such damage may invalidate the warranty.

 

Descriptions

 

The screw terminals on the STP-36CJC screw terminal connector let you connect field wiring to the analog connector on the
KPCI-3108/7 board using a CAB-1284CC cable. The screw terminals are labeled from 1 to 36 and correspond directly to the
functions of the pins on the main analog I/O connector on the KPCI-3108/7 board. For example, if pin 24 is assigned to the
analog function OP0, use screw terminal 24 to attach hardware to output 0. Refer to the KPCI-3108/7 Series User’s Manual  for
detailed wiring information on connecting the STP-36CJC.
