Introduction
The N-IO field enclosure is a standardized remote I/O enclosure for outdoor use, which
include N-IO node. There are two types of N-IO field enclosure, one is for CENTUM VP and
the other is for ProSafe-RS.
This document provides guidance that allows users to consider how to accumulate
the power capacity and install devices at a planning stage of deploying the N-IO field
enclosures for CENTUM VP and ProSafe-RS.
Chapter 1 System installation requirements
This chapter describes specifications covering N-IO field enclosure installation and
environmental specifications, inrush current, power consumption, noise prevention, and
grounding necessary for designing a power supply system.
Chapter 2 Transportation, storage and installation
This chapter describes general cautions for transporting and carrying the N-IO field enclosure
which is a precision device, precautions for temperature and humidity changes when unpacking
or storing it temporarily, space necessary for maintenance (servicing area), and how to install
devices.
Chapter 3 Cabling
This chapter describes how to connect power, grounding, signal and communication cables to
the installed devices, and how to connect optical fiber cables.
Chapter 4 Installation specifications
This chapter covers power consumption and power dissipation, in-rush current, circuit protector
and breaker ratings, and parts that need replacement within 10 years. Read this section when
deciding power supply capacity.
Chapter 5 Post-installation inspection and environmental preservation
This chapter describes items that must be checked before applying power and the precautions to
be taken to safeguard the environment after installing the system.
