Flame Proof Enclosure: Ex d IIB
The electric motor consists of one ameproof enclosure, which contains less than 6%
magnesium by weight. The on/o switch is housed within the motor enclosure, and is
operated by a shaft, extending out from the rear end bell to a lever. The lever is accessible
via an attached push rod.
Motor connections are made through a non-detachable cable, secured to the motor with
an approved Flame Proof cable gland from the company Hawke, model 501/421/0/M20
and complies with International Standards EN 60079-0, EN 60079-1, and EN 60079-7.
The electric motor drives an aluminum or plastic fan blade which is enclosed in a plastic,
statically conductive housing with a conductivity rating of <1 giga ohms. Connection to
the motor is facilitated by a Terminal Block mounted in an Increased Safety/Flame Proof
Enclosure rated II 2 G Ex e II T6, from the company Rose Industries, Part Number 05080806,
and covered under ATEX Certicate No. PTB 00ATEX1063. This box was designed to
conform to International Standards EN 60079-0, EN 60079-1, EN 60079- 7, IEC/EN 60079-31.
The enclosure features stainless steel grounding lugs, with a high heat silicon gasket.
The Flame Proof enclosure has attached, approved, explosion proof cable glands, as
described below.
Rated: II G Ex e II
Type: Polyamide Ex metric conforms to International Standards EN 60079-0, EN 60079-1,
EN 60079-7, IEC/EN 60079-31.
Material: Polyamide Color: Black/Blue

Temperature Range: -4°F to +212°F Approval: PTB 00 ATEX 1063
If the fan power cables are not terminated with power plugs see Special Conditions for safe
use.
The fans are assembled with both Inlet and Outlet Safety Guards that conform to the safety
standards to prevent danger zones being reached by upper limbs in the BS EN ISO 12100
Safety Machinery – Guards Standard.
Installation and Start-Up
• During the installation and start-up of the RAMFAN blowers in areas where there is a
risk of explosion:
• Design of the electrical installations must be in accordance with EN/IEC/ABNT NBR IEC
60079-14.
• Ensure power source is providing an electrical ground.
• Blowers must be integrated into a system in a way to support accessibility for regular
maintenance.
• Blowers are designed for portable, nonxed installation. Blowers have no mounting
features to support rigid duct or x installations.
• Perform careful inspection of each blower system to ensure ducting is securely
attached to blower. All components of the blower system are made of electrically
conductive material. It is very important to properly and securely attach each
component to maintain a ground path.
• Inspect fan power cable and plug for damage or wear that could render the cable
unsafe for hazardous locations.
• Ensure set-up, installation, operation and maintenance are performed only by properly
trained personnel.
• Operation after a faulty installation or maintenance shall be considered as
Before STARTING the FIRST time
DO NOT start operation if there are any signs of shipping damage to the blade, guards or
housing. STOP, call your dealer. USE Ex-Rated receptacles for this equipment. IT IS NOT
recommended to use extension cords for high amperage load. (See power rating label on
limit)
