Locations
This section contains important information regarding
installation of the IPT
2
in Hazardous Area Locations.
This equipment is suitable for use in Class I, Division
2, Groups A, B, C & D or non-hazardous locations
only. Field wiring shall be rated for 85˚C.
WARNING:
Explosion Hazard. Do not disconnect
equipment when a fl ammable or combustible
atmosphere is present.
AVERTISSEMENT:
Risque d’explosion. Ne pas
débrancher tant que le circuit est sous tension,
a moins qu’il ne s’ agisse d’un emplacement non
dangereux.
WARNING:
Explosion Hazard. Substitution of
components may impair suitability for Class I,
Division 2.
AVERTISSEMENT:
Risque d’explosion. La substitution
de composants peut rende ce materiel inacceptable
pour les emplacements de Classe I, Division 2.
WARNING:
Explosion Hazard. Test Jacks (-T and
+T) shall not be connected or disconnected when a
fl ammable or combustible atmosphere is present.
Special Conditions of Use
The following instructions must be adhered to when
the IPT
2
is used in hazardous locations and potentially
explosive atmospheres.
The IPT
2
shall be installed in compliance with the
enclosure, mounting, spacing and segregation
requirements of the ultimate application.
The IPT
2

Electrical Connections
The electrical connections are made to the removable
terminal blocks located on the front of the unit. There
are two terminals on the IPT
2
for connecting input
current.
The electrical terminals are compression screw
sockets that accept 22 to 14 AWG hookup wire. To
complete these connections, use a slotted screwdriver
with a head approximately 0.125 inch (3mm) in width
to secure the wire leads to the transmitter. Loosen
each screw prior to inserting the wire being terminated.
Strip and then tin the end of each wire with 60/40
solder. Then, while holding the uninsulated end of the
wire in place, tighten the screw of the corresponding
terminal.
Recommended Ground Wiring Practices
Moore Industries recommends the following ground
wiring practices:
• Any Moore Industries product in a metal case
or housing should be grounded.
• The protective earth conductor must be connected
to a system safety earth ground before making
other connections.
• All input signals to, and output signals from, Moore
Industries’ products should be wired using a
shielded, twisted pair wiring technique. Shields
should be connected to an earth or safety ground.
