EQ3XXX CONTROLLER
INSTALLATION
The following paragraphs describe how to properly
install and configure the EQ3XXX Controller.
ENCLOSURE REQUIREMENTS
The Controller must be properly installed in a suitable
enclosure that is rated for the location. The enclosure
must provide space to install and wire the Controller
and must also provide for ground wire termination.
The enclosure must contain either a keyed lock or a
special tool to gain access into the enclosure. The
enclosure should be rated for the temperature range
of the location plus the temperature rise of all
equipment installed inside the enclosure. The
enclosure must be rated for electrical equipment that
is going to be installed.
NOTE
The Controller and enclosure must be
connected to earth ground.
For ordinary locations when entry is required to
operate the equipment, the cabinet should be a
dead-front construction and 16-gauge cold-rolled
steel. The door lock system shall accept different
keys for entry. An Authorized Persons key and a
Person-in-charge key will allow entry into the cabinet.
The cabinet should contain a window to view the
Controller’s text display and LED indicators.
NOTE
For any selected enclosure, the enclosure must
conform to all applicable regulations and
requirements.
NOTE
The Trouble signal must be located in an area
where it is likely to be heard.
Classified locations require the appropriate hazardous
rated enclosure. It is recommended that operators/
switches be installed in the enclosure. This avoids
the need to declassify the area in order to operate the
Controller. Regulations require that key switches be
installed for certain operations. An appropriate
window should be part of the enclosure in order to
allow an operator to view the text display and LED
indicators.
NOTE
If an enclosure does not have a keyed entry, a
special tool is required to gain entry into an
enclosure.
Det-Tronics offers several approved (FM/CSA/ATEX/
CE) hazardous area enclosures that have Eagle
Quantum Premier equipment installed in the
enclosure. Contact Det-Tronics for further information.
MOUNTING
The Controller is designed for direct panel mounting
or DIN rail (optional) mounting. See “Specifications”
section of this manual for mounting dimensions.
NOTE
Clips for DIN rail mounting are available, but
must be specified at the time of ordering.
NOTE
A minimum clearance of 4 inches between the
Controller and nearby equipment is required to
provide room for wiring and ventilation.
SERIAL INTERFACE BOARD
An optional Serial Interface Board is available for the
EQP Controller. See Figures 3-8 and 3-9 for details on
the electrical connections.
