Installation Preparations

2.1

Installing the Mounting Bracket

2.2

Installation Space Expansion Bolt

(1) Expansion sleeve

(2) Flat washer

(3) Spring washer

(4) M12x60 bolt

The M12x60 expansion bolts and M12x40 bolt

assemblies are supplied with the SmartACBox.

M12x40 bolt assemblies are used for support-

mounting and pole-mounting the SmartACBox.

Such a bolt assembly consists of a flat washer,

a spring washer, and an M12x40 bolt.

The mounting bracket has four groups of tapped holes, each group containing four tapped holes.

Mark any hole in each group based on site requirements and mark four holes in total. Two round

holes are preferred.

Wall-mounted Installation

Avoid drilling holes in the utility pipes and/or cables attached to the back of the wall.

NOTE

1. Mark hole positions.

Support-mounted Installation

3. Secure the mounting bracket.2. Install expansion bolts.

1. Mark hole positions. 2. Drill holes. (You are advised

to apply anti-rust paint on the

hole positions for protection.)

3. Secure the mounting

bracket.

•To prevent dust inhalation or contact with

eyes, wear safety goggles and an anti-

dust respirator when drilling holes.

•Clean up any dust in and around the

holes using a vacuum cleaner and

measure the distance between holes. If

the holes are inaccurately positioned,

drill a new set of holes.

•Level the head of the expansion sleeve

with the concrete wall after removing the

bolt, spring washer, and flat washer.

Otherwise, the mounting bracket will not

be securely installed on the concrete

wall.

•To pole-mount a SmartACBox, you need to prepare pole-mounting brackets by yourself based

on the SmartACBox dimensions. You are advised to use M12 U-shaped bolts to secure the

pole-mounting brackets.

•Figures are for reference only. The actual poles and pole-mounting brackets prevail.

Pole-mounted Installation

1. Secure the pole-mounting brackets. 2. Secure the mounting bracket.

Securing the Enclosure

2.3

2. Install the enclosure on the

mounting bracket. 3. Tighten the security torx screws using a

security torx wrench.

NOTE

1. Remove the security torx wrench

and enclosure door key from the

base of the enclosure and save them

for later use.

3Opening the Enclosure Door

•Before opening the enclosure door, turn off all upstream switches for the SmartACBox. If you

have to operate an energized SmartACBox, wear insulation gloves and take preventive

measures.

•If you need to open the enclosure door on rainy or snowy days, take protective measures to

prevent rain or snow from entering the enclosure. If it is impossible to take protective measures,

do not open the enclosure door on rainy or snowy days.

2. Open the enclosure door and install the

support bar. 3. Hold the handles on the cover and

remove the cover.

1. Insert the key into the lock hole in the enclosure door and open the lock.

4Installing the Router

•The SmartACBox is not factory-installed with a router, so you need to purchase and install a

router by yourself.

•This document introduces how to install an SC-RRX230 or SC-RRX280 router produced by

SUN DENSI in Japan.

NOTE

Installing the Router Antenna

4.1

Remove the four screws from the cover. Start from the one at the lower left corner, and then the

rest in counterclockwise sequence.

NOTE

An SC-RRX230 or SC-RRX280 router is supplied with a 1P184-FMM800W-5M5 or 1P184-DP-

BR0-RE remote outdoor antenna.

NOTE

1. Remove the screw assemblies from the router tray and remove the antenna support.

2. Install the antenna support in the upper part of the left wall of the enclosure and secure it using

the removed M4 screw assemblies.

3. Secure the router antenna on the support by attaching the antenna base to it.

1P184-DP-BR0-RE Antenna

1. Remove the screw assemblies from the router tray and remove the antenna support.

2. Align the fixing holes in the antenna base with the holes in the antenna support and secure the

antenna base to the antenna support using screws.

3. Install the antenna support in the upper part of the left wall of the enclosure and secure it using

the removed M4 screw assemblies.

The screws used for tightening are supplied M5 screw assemblies.

NOTE

Installing the Router SIM Card

4.2

1. Remove the SIM card

shielding cover from the

router panel.

2. Insert the SIM card.

3. Reinstall the SIM card

shielding cover.

Securing the Router

4.3

1. Loosen the captive

screws and remove the

router tray.

2. Horizontally place the

router on the tray and

ensure that the DC-IN

port on the router faces

the power compartment.

Then, secure the router

by routing the supplied

M4 Phillips screws

through the holes at the

bottom of the router tray

and the holes at the

bottom of the router.

3. Place the router tray

back onto the router

support and tighten the

captive screws.

5General Operations

•Pay attention not to damage

the core wire when stripping

a cable.

•The cavity formed after the

conductor crimp strip of the

OT terminal is crimped must

wrap the core wires

completely. The core wires

must contact the OT

terminal closely.

•Wrap the wire crimping area

with heat shrink tubing or

PVC insulation tape. The

following figure uses heat

shrink tubing as an example.

•When using the heat gun,

protect devices from being

scorched.

Knocking Off the Barrier Chip from a Cable Hole

5.2

•Before connecting the PE cable, AC input

power cable, and AC output power cable

for the first time, knock off the barrier chips

from the cable holes 1 and 2 for the AC

input power cable and the cable hole for

the AC output power cable.

•The edges of the cable holes for the AC

input and output power cables are sharp.

Recommended: Use a file to smooth the

edge of the cable hole. Protect yourself

during operation from being hurt.

•The FEK-65B cable glands of Mirai

Industry Co., Ltd. are recommended for

the cable holes for the AC input and output

power cables.

Routing a Cable Through a Cable Gland (COM)

5.3

1. Remove the gland and cap

from the cable gland.

2. Route the cable through the

gland and then cable gland.

3. Connect the cable.

4. Tighten the gland.
