How to install Johnson AE55/NIE55?

Equipment Overview and Application Scenarios

core positioning

NAE (Network Automation Engine) and NIE (Network Integration Engine) are monitoring devices that support web access and are based on Ethernet. Their core functions are to monitor and control on-site building automation equipment, HVAC equipment, and lighting systems. Unless otherwise specified in the document, the MS-NAE55xx-x and MS-NIE55xx-x series are collectively referred to as NAE55.

Emission compliance requirements

United States: Compliant with FCC Part 15 Class A digital device restrictions, only applicable to commercial environments. If interference occurs in residential environments, users need to resolve it themselves.

Canada: Meets the requirements of the Canadian Interference Equipment Regulations (R è glement sur le mat é riel brouilleur du Canada).

Preparation before installation

Package contains components

1 NAE55 host

1 data protection battery (individually packaged)

1 installation manual

Required materials and specialized tools

4 fasteners for compatible mounting surfaces (M4 screws for Europe, # 8 screws for North America)

2 sections of DIN rails 36 centimeters (14 inches) and above (only for DIN rail installation scenarios)

1 small flathead screwdriver (used to fix the communication cable of the terminal block)

Installation environment requirements

Stay away from corrosive gases and follow the environmental restrictions specified in the technical specifications.

Avoid installing on surfaces that are prone to vibration (such as pipelines) or near electromagnetic interference sources (to prevent interference with communication).

Reserve sufficient space for wiring and terminal connections (refer to size requirements in Figure 2).

The power supply should not be installed below NAE55.

When installing panels/enclosures, it is necessary to avoid sealing the enclosure and ensure that the enclosure walls or transformers do not obstruct the equipment ventilation openings.

Devices that cause the temperature of the NAE55 processor to exceed 77 ° C (171 ° F) must not be added inside the casing (embedded temperature sensor data must be viewed through diagnostic tags).

Installation process

Installation method selection

NAE55 supports three installation methods: wall mounting, DIN rail mounting, and shell mounting. The core operations are as follows:

1. Wall installation (vertical surface)

Mark the four installation hole positions on the wall according to the dimensions in Figure 3 (horizontal installation hole spacing of 317.5mm, vertical installation hole spacing of 63.5mm) or directly using the host as a template.

After drilling, if anchor bolts need to be fixed, they should be inserted into the holes. First, screw the screws into the top two holes, leaving enough space to accommodate the installation feet.

When installing horizontally, hang the top mounting foot of the host on the screw; When installing vertically, the host needs to be held in a fixed position.

Insert the screws into the two holes at the bottom, being careful not to tighten them too tightly (to avoid damaging the mounting feet or housing).

2. DIN rail installation

Install two sections of DIN rails horizontally, with a center to center distance of 125 millimeters (4.9 inches).

Pull the DIN buckle at the bottom of the host to the outer position.

Hang the DIN rail hook on the back of the host onto the rail.

Push the DIN buckle back to its original position and secure the host.

Disassembly steps: First, move the DIN buckle to the outside, and then remove the host from the guide rail.

3. Shell installation

Install the casing according to the manufacturer's instructions.

Following the "Installation Environment Requirements" and the above installation specifications, fix NAE55 inside the casing.

Special installation requirements

The UL 864 certified models (MS-NAE5510-0U and MS-NIE5510-0U) must be installed inside a lockable housing.

Wiring operation

Precautions before wiring

Before wiring, a data protection battery must be installed (see "Settings and Adjustments" section), and a 24VAC power supply must not be connected.

Only copper conductors are used, and wiring must comply with local, national, and regional regulations.

Do not exceed the electrical rating of the equipment (NAE55 is a low-voltage equipment,<30VAC), and do not connect to high voltage (otherwise the equipment will be damaged and the warranty will be invalidated).

The terminal block key must not be removed, and the terminal plug and socket are designed to be foolproof and can only be correctly connected.

Prevent electrostatic discharge (avoid damaging equipment and void warranty).

The power cord and communication cable should be kept at least 50 millimeters (2 inches) away from the ventilation duct on the side of the equipment.

Reserve a certain degree of slack in the cables, and arrange the wiring neatly to ensure ventilation, LED visibility, and maintenance convenience.

Core wiring steps

Ethernet connection: Insert the Ethernet cable into an 8-pin RJ-45 Ethernet port (supporting 10/100 Mbps).
