About This Manual
The IQ plus 310A XPCD explosion proof digital weight indicator represents the latest in state-of-the-art
microprocessor technology specifically applied to the explosion proof weighing marketplace. This IQ plus 310A
has been modified for use in a hazardous environment.
This manual provides information on installation of the IQ plus 310A XPCD. The installer should be familiar
with the National Electrical Code and RP 12.6 ( Recommended Practice ) requirements for installation of
equipment in hazardous areas (NEC Article 504, Intrinsically Safe Systems ) published through the Instrument
Society of America.
This equipment is intended only for industrial applications.
This instrument and accompanying equipment must be installed and serviced by an
authorized technician in accordance with the instructions provided in this manual.
Improper specification, installation, or service of this equipment could result in personal injury or property
damage.
Read all of the manual prior to installation. Do not assume that all hazardous area installations are identical.
Do not begin installation until all safety procedures are in place including lockouts, additional ventilation, or
washdowns. Make sure plant safety personnel have checked the area in which you will be working and have
officially declared it safe for work to proceed.
All explosion proof enclosures must remain closed unless being serviced by qualified personnel in an area
which safety inspectors have tested and declared safe. Each opening must have a sealoff fitting or plug
correctly installed in it. Sealoff installation is critical. Maximum voltage inside of enclosure must not exceed
250VAC.

The design intent of an explosion proof enclosure is not to contain an explosion, but to control it. The flame
path is carefully controlled at the flanges. This insures that if an explosion occurs, any gases that escape will
be cooled to a temperature below the ignition point of any atmosphere specified within that enclosure’s
rating.

2.0 Installation and Wiring
This section is provided to help the installer and describes the procedures for installing the IQ plus 310A XPCD
indicator and enclosure, AC wiring, load cell wiring, conduit runs and internal modifications for the IQ plus
310A XPCD.
2.1 IQ plus 310A XPCD Enclosure
The following sections describe mounting locations and how to mount the enclosure and seal off the fittings.
2.1.1 Mounting and Mounting Locations
The mounting and installation of an explosion proof enclosure is more involved than a general purpose unit and it
is recommended that all outdoor installations have a shelter, roof, enclosure, or covering. The IQ plus 310A
XPCD enclosure is cast aluminum and direct sunlight can cause it to heat to a very high temperature which can
damage the electronics inside. (Such damage is not covered by the warranty). Sheltering the unit from sunlight
will help control the internal temperature.
Sunlight and variable temperatures can also cause moisture to condensate inside the enclosure. It is
recommended to shelter the outdoor installation by a shelter, roof, enclosure, or covering. Moist environments
can also be controlled by the use of desiccants. Contact your local dealer for information on desiccants.
Do not place desiccants on top of circuit boards. Place them in the bottom of the
enclosure away from electronics and wires.
The explosion proof enclosure is substantially heavier than a standard enclosure and thus the mounting surface
must be capable of reliably supporting the added weight.
The mounting and installation of the IQ plus 310A XPCD must be into Division II or safe electrical area per
NEC, Section 500. The inside of an explosion proof enclosure is classified as a Division II environment.
Switches and Glass
The glass and switches on the IQ plus 310A XPCD may look indestructible but they are not. If damaged in any
way, the entire unit must be completely turned off at the source until it is replaced. The enclosure must be
protected from blows and scrapes from passing equipment, falling objects, thick glues or resins, certain acids
which eat aluminum, and other hazards which can break or damage the enclosure.
The glass window in the enclosure must be not become scratched, pitted, or damaged in any way. Do not wipe
the glass with dirty gloves or rags as this can cause the glass to become scratched.
!Caution
DISCONTINUED

Installation and Wiring 7
2.2 Sealoff Fittings
The utmost care must be taken to completely seal the inside of the enclosure off from the outside world. To do
this all wiring into and out of the enclosure must be in conduit using sealoff fittings between the enclosure and
the conduit. The sealoff fittings ensure that the hazardous atmosphere does not travel either through the conduit
or through insulation or wiring back to the safe area. The graphic shown below illustrates the location of sealoff
fittings.
These fittings, once installed and sealed are very difficult to remove so make sure all the wiring has been double
checked before beginning. If rigid conduit is not being used for connection to the scale base, be sure to install an
approved strain relief fitting to avoid pulling the wires out of the sealoff fittings in an accident. Doing so would
open a flame path to the enclosure and defeat its purpose.

2.3 Cabling and Conduit Runs
2.3.1 Cabling
There are two types of cables that pass through a sealoff fitting, single conductor and multi conductor.
Single Conductor Cabling
Single conductor cables are typically redundant ground wires (used with resistive intrinsic safety barrier). Due to
the nature of the method by which insulation is applied to wire, a single conductor wire (single or multi strand)
can be considered gas tight. It is not necessary to strip the insulation back ahead of entry into the safe area. Single
conductor cables will pass through a sealoff fitting as shown below.
Figure 2-1. Single Conductor Cable
Multi Conductor Cabling
Multi conductor cables may be load cell cables, AC power, serial data inputs or other signals. Because of the
airspace that typically exists within the outer insulation of a multi conductor cable, they cannot be considered gas
tight. Therefore, to insure that the explosion proof enclosure is allowed to vent internal pressure appropriately,
the outer insulation must be removed back to the point ahead of entry into the safe area. Multi conductor cables
will pass through a sealoff fitting as shown below.
Figure 2-2. Multi Conductor Cable
A sealing fitting must be installed within 18" of the enclosure for Groups C-G and 6" for Groups A and B.
Using the enclosed packing fiber and sealing cement, follow the directions for sealing the sealoff fittings
carefully. Make sure there are no openings, no matter how small to the outside.
An enclosure without sealoff fittings correctly installed and sealed is not explosion proof
therefore can pose serious injury or death.

2.3.2 Conduit Runs
Conduit can be run either vertically or horizontally. But either way the conduit must be sealed properly to
maintain the explosion proof integrity of the unit. The following paragraphs explain the proper way to install a
conduit run and the sealing fittings.
Horizontal Conduit Runs
Install the fitting with covered filling opening facing up. Remove the threaded cover and pack Adaco
®
packing
fiber around and between cables at both ends of fitting to block the flow of cement into conduits. Packing fiber
must not project into the main cavity of fitting. The cavity length free of packing fiber must be at least equal to
inside diameter of conduit but not less than 5/8".
Mix the cement per label instructions using the enclosed shipping container. Fill the container with clean cold
water to “water line” (make sure not to exceed required amount of water). Gradually pour cement from the
plastic bag into water and stir thoroughly for proper mixture. Fill the fitting in one continuous pour to the top of
filling opening within five minutes after mixing cement. Tamp with a blunt stick to expel any air bubbles. Install
and tighten filling opening cover.
Fittings requiring more than 16 oz. of cement must be filled from a single mixture of cement and water. Do not
pour in stages.
Water-mix sealing compound should not be poured or installed at temperatures below 35F.
Vertical Conduit Runs
Install the fitting with angled fill plug or cap fill plug towards the top. Remove angled fill plug, large hole plug or
threaded cover. Pack fiber around and between cables at lower end of sealing fitting to block flow of cement into
conduit. Packing fiber must not project into main cavity of fitting. Install and tighten large plug or threaded cover
with fill plug facing up but do not install fill plugs at this time.
Mix the cement per label instructions using the enclosed shipping container. Fill the container with clean cold
water to “water line” (make sure not to exceed required amount of water). Gradually pour cement from the
plastic bag into water and stir thoroughly for proper mixture. Fill the fitting in one continuous pour to the top of
filling opening within five minutes after mixing cement. Tamp with a blunt stick to expel any air bubbles. Install
and tighten fill plug.

2.4 AC Power Wiring
Electrical connections made in an explosion proof installation are made through rigid steel conduit through
threaded openings in the back or sides of the enclosure and must comply with the National Electrical Code for
installation of equipment in hazardous areas (NEC Article 504, Intrinsically Safe Systems ).
Connect an electrically separate source of 115 VAC 60HZ to the terminals on the user wiring board marked
L1,
L2, GND.
Figure 2-3. AC Power Wiring
Do not apply power at this time.
Recheck all connections and make sure there are no hazards in the surrounding area, and turn on power. The
meter should come on and do a normal lamp test.

2.5 Intrinsic Safety Barriers
The IQ plus 310A XPCD is designed to be used by personnel already trained and familiar with intrinsic safety
barriers. They are designed to self destruct if a dangerous condition occurs.
Note:
If you are not trained to work on this equipment, stop. Call you scale dealer for assistance.
All intrinsic safety barriers have five terminals (shown below).
Figure 2-4. Intrinsic Safety Barrier
Terminals three and four are the intrinsically safe connections. Devices in the hazardous location are connected
to these terminals. Terminals one and two are the non-intrinsically safe connections for devices within the
non-hazardous location. The maximum source voltage applied to these terminals under a fault condition must not
exceed 250 V rms.
Along with the four terminals mentioned above, two additional screw terminals are provided, one on each side of
the barrier.
They are directly attached to the barrier mounting/grounding system and can be used to establish a redundant
ground system or for terminating shields. On single channel barriers they are also internally connected to
terminals two and four.
Since a common housing is shared between single, dual, and application dedicated barriers, refer to the
schematic printed on the side of each barrier to determine the designation of the floating and grounded terminals.
If an instrinsic safety barrier self destructs, do not replace it. Find out what caused the problem. Do not assume
the problem can only be in the indicator.
Only when the problem is corrected should a barrier be replaced with the exact same brand and type.
2.5.1 Intrinsic Safety Grounding
Special attention must be given to the grounding system. Without a proper earth ground system, intrinsic safety
barriers will not provide voltage protection. They must therefore be grounded to a designated grounding
electrode that references the original power source and instrumentation within the non-hazardous location. This
source of ground must be less than 1
Ω from the true earth ground.
