Preface

Equipment components are SENSITIVE to electrostatic discharge (ESD).
Undetectable permanent damage can result if you do not use proper ESD
procedures. Ground yourself, your work surface, and this equipment
BEFORE removing any cover from this equipment. If your facility is not
equipped to work with these components, contact NR about returning this
device and related NR equipment for service.

Insufficiently rated insulation can deteriorate under abnormal operating
conditions and cause equipment damage. For external circuits, use wiring
of SUFFICIENTLY RATED insulation that will not break down under
abnormal operating conditions.

SEVERE power and ground problems can occur on the communications
ports of this equipment as a result of using non-standard cables. Please use
the wiring method recommended in the manual for communication terminals.

DO NOT connect power to the relay until you have completed these
procedures and receive instruction to apply power. Equipment damage can
result otherwise.

Use of controls or adjustments, or performance of procedures other than
those specified herein, may RESULT IN hazardous radiation exposure.

The firmware may be upgraded to add new features or enhance/modify
existing features, please MAKE SURE that the version of this manual is
compatible with the product in your hand.
