Mier products Acht series User manual

Also Available:

* BP Series - Enclosures with back panels. Some of

these are NEMA 4 and can be used with one of Mi-

er’s accessory heater/blowers if you only want heat.

* Non-Metallic Series - NEMA 4X & UL listed

polycarbonate enclosures (some models rated

up to NEMA 6/6P). These are also available with

heater/ blowers if you only want heat.

* Indoor DVR/CPU Lockboxes - Indoor standard,

tower, rack-mountable, 12RU rack-enclosure, and

12RU rack-cart models. All lockboxes come with

fans and louvers for ventilation

ATTENTION: When choosing an enclosure for your application,

careful consideration must be given in determining the heat load

and operating temperature parameters of the electronics mounted

within. Also consider the conditions of the environment where

the unit is to be mounted, and the moisture toleration of the

electronics mounted within. Based on these facts, the need for air-

conditioning, humidity control, heat, and/or fans can be determined

as well as the NEMA rating needed. (For example, if the electronics

cannot be exposed to moisture of any kind, a NEMA 3R fan-

ventilated unit would NOT work; you would need at least a NEMA 4

or NEMA 4X unit.) Mier commonly recommends the highest NEMA

rated and most effective Temperature Controlled units which are

the “ACHT” series enclosures.

NOTE: To keep NEMA Rating, installers must strictly

follow OEM installation instructions and must use water-

tight ttings on all openings.

Keep in mind, depending on the model you purchase, some ACE or ACHT units have less or more cubic volume inside.

Units with the 2000 BTU A/C Unit, and units with the 500 Watt Heater (aka: T-20s) - with an internal heat load of 200 watts:

Mier’s “• ACHT” and “ACE” models which come with a 2000 BTU A/C Unit, when installed and functioning properly, will maintain an internal

preset temperature of (+/- 30F). For example the BW-124ACE (enclosure size 24”W x 24”H x 12”D) is capable of maintaining an 800F internal

temperature (+/- 30F) up to an outside temperature of 1350F.

Mier’s “• ACHT” models which come with a 500W Heater integrated into the A/C unit, when installed and functioning properly, will maintain an

internal temperature (+/- 30F). For example the BW-124ACHT (enclosure size 24”x24”x12”) maintains a preset temperature (+/- 30F) up to a

maximum of up to 600F with an outside temperature of -200F. The BW-136ACHT (enclosure size 24”x36”x12”) maintains a preset temperature

(+/- 30F) up to a maximum of up to 600F with an outside temperature of -100F.

Units with the 800 BTU A/C Unit, and units with the 150 Watt Heater (aka: T-15s) - with an internal heat load of 100 watts:

Mier’s “• 8ACHT” and “8ACE” models which come with the smaller 800 BTU A/C Unit, when installed and functioning properly, will maintain

an internal preset temperature (+/- 30F). For example the BW-1248ACE (enclosure size 24”x24”x8”) is capable of maintaining an 800F internal

temperature (+/- 30F) up to an outside temperature of 1250F.

Mier’s “• 8ACHT” models which come with a 150W Heater integrated into the A/C unit, when installed and functioning properly, will maintain an

internal temperature (+/- 30F). For example the BW-1248ACHT (enclosure size 24”x24”x8”) maintains a preset temperature (+/- 30F) 400F inter-

nal temperature down to an outside temperature of -200F.

Mier’s Temperature Controlled Enclosures are completely sealed with no knockouts or holes in the enclosure other than those for

mounting the AC unit. When installed correctly with the AC unit they meet NEMA 4 standards and may be used either indoors or outdoors,

and provide a degree of protection to personnel against incidental contact with the enclosed equipment, and they provide a degree of protection for

the equipment within from windblown dust, splashing water, hose-directed water, rain, sleet, snow, ice, & dirt.

Mier Products’ Temperature Controlled Enclosures

Installation and Warranty Information

Power:

Once installed correctly, the power cords for the AC unit and the heater are within the enclosure. Thus, the installer/electrician is responsible for get-

ting power inside the enclosure. It is up to the installer to cut, andproperlyinstallwithwater-tightttings, any holes needed to run power within or

run cables out of these enclosures.

Both the AC unit and the heater get their power from AC 115V, 60hz. Mier recommends the installer/electrician run power into the box via exible or

rigid conduit, with water-tight ttings, to outlet boxes mounted within the enclosure.

Wiring: use #12 AWG standard house wiring to a quad outlet box

Connection: the AC/Heater unit has a standard 3-prong NEMA 5-15P plug and the tamper switch connects to the standard low-voltage alarm circuit.

Mier Recommends using at least two people to pole-mount

heavy enclosures, and performing steps 1-4 PRIOR to going to

job site.

1) Mark the center point of each Mounting Rails (A).

2) Slide the Adjustable Band Guides inside both Mounting

Rails, and center them to the point marked on step 1 (B).

3) Place the 1/4” x 20 Screws and 1/4” Washers on the outside

of the Mounting Rails, run the bolts through the Mounting Rails

and Adjustable Band Guides, and secure with the 1/4” x 20

locknuts on the inside (C and B).

4) Insert the two (2) Heavy-Duty Adjustable Bands into the

two (2) Adjustable Band Guides inside the Mounting Rails.

The bands should curve outwards, away from the inside of the

Mounting Rails. One (1) of these Heavy-Duty Adjustable Bands

goes in each of the Adjustable Band Guides assembled inside

each of the Mounting Rails (D).

5) Attach the two (2) assembled Pole-Mount Rails onto the two

(2) Mounting Lips of the Enclosure using the four 3/8” x 16

Carriage Bolts entering through the inside of the Mounting Rail,

use TWO (2) of the eight 3/8” EXTRA THICK Washers ON EACH

bolt between the rail and the enclosure lip for proper spacing,

then use the 3/8” Standard Washers on the outside of the Enclo-

sure Lip with the 3/8” ange-nuts (E).

6) Wrap the bands around the pole and use a power driver with

a straight blade screw-driver, or a 3/8” socket tting, to tighten

the bands securely around the pole (F). F
