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 Certificate No. PTB 00ATEX1063. This box was designed to conform to
International Standards EN 60079-0, EN 60079-1, EN 60079-7, EN 61241-0 and EN 61241-1.
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.

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, nonfixed installation. Blowers have no mount
ing features to support rigid duct or fix 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.
• 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
unintended use.
