SAFETY SYSTEM DESIGN
REQUIREMENTS
Many factors need to be considered when
determining proper EQP System design. The
following paragraphs will discuss these factors
and other issues useful in designing, installing
and configuring the Eagle Quantum Premier
System.
IDENTIFYING THE AREA OF PROTECTION
In order for the system to provide optimum
coverage and protection, it is critical to properly
define the required “Area of Protection” (total
area being monitored by the system). The area
of protection should include all hazard sources
requiring monitoring, as well as suitable
locations for mounting detection, extinguishing,
notification, and manual devices. In order to
accurately define the area of protection and
provide maximum protection, all potential
“Real” and “False” hazard sources must be
identified. The number and location of Real
Hazards determines the extent of the area of
protection, and impacts all subsequent design
decisions.
WARNING
When drilling through surfaces in the
process of mounting equipment, verify
that the location is free of electrical
wiring and electrical components.
IDENTIFYING WIRING, NETWORK (LON),
AND SYSTEM POWER REQUIREMENTS
General Wiring Requirements
WARNING
DO NOT open any junction box or device
enclosure when power is applied without
rst de-classifying the hazardous area.
CAUTION
Any deviation from the manufacturer’s
recommended wiring practices can
compromise system operation and
effectiveness. ALWAYS consult the factory
if different wire types or methods are
being considered.
NOTE
All eld wiring must be marked per NFPA
70 Article 760.
NOTE
Specific installation requirements may
differ depending on local installation
practices and compliance with third
party certications. For local installation
practices, consult the local authority
having jurisdiction. For compliance with
third party certifications, consult the
appropriate appendix in this manual for
additional installation requirements.
Power Wiring
IMPORTANT
To ensure proper operation of field
devices, the voltage input to the device
(measured at the device) must be within
the range indicated for that device in the
“Specifications” section of this manual
(18 Vdc minimum).
System Wiring (ATEX and IECEx)
For the interconnection of the modules within
the EQP system, use fixed installed wiring.
(For correct wiring size and type for a specific
device, refer to the appropriate section in this
manual.)
For ambient temperatures below –10°C and
above +60°C, use field wiring suitable for both
minimum and maximum ambient temperatures.
The EQP Ex n modules may only be installed,
connected, or removed when the area is known
to be non-hazardous. The screw terminals are
to be tightened with a minimum torque of 0.5
Nm. Equipotential bonding connection facilities
on the outside of electrical equipment shall
provide effective connection of a conductor
with a cross-sectional area of at least 4 mm
