RTP3034SPG
RTP Surge Protector with Isolated Ground
1. PREPARATION
DANGER: Possible electrical shock or burn hazard.
Only qualified personnel should install this product. Failure to
lockout electrical power during installation or maintenance can
result in fatal electrocution or severe burns. Before making any
connections please ensure that power has been removed from all
associated wiring, electrical panels, and other electrical
equipment.
CAUTION:
1. The installation of this Remote Transmitter Protector (RTP)
should follow and observe nationally recognized codes of
authorities having jurisdiction to ensure correct and safe
operation.
2. Check to ensure that the maximum continuous operating
voltage Uc of the RTP is higher than that expected on the
circuit being protected.
3. It is important to ensure that the maximum line current rating
IL of the RTP is not exceeded.
4. The ground (earth) terminal must be connected to a low
impedance earth (<10 ohms) for correct operation.
5. Do not perform a "Flash Test" or use a Megger to test
circuits that are protected with these RTP units. This may
damage the RTP(s) and affect the insulation readings being
performed.
6. The RTP must be installed in a dry non-condensing
environment.
7. Do not attempt to tamper with the RTP unit in any way as
this may compromise performance and will void warranty.

2. INTRODUCTION
The ERICO CRITEC Remote Transducer Protector (RTP) has been
designed to protect field 4-20mA transducers and transmitters from the
damaging effects of surges on low voltage data, control and signaling
lines. Its stainless steel ¾" (NPT thread) pipe housing makes the unit ideal
for direct connection to the spare transducer port or installation into the
wiring conduit. The unit is suitable for use in outdoor environments. The
internal protective module provides screw terminals for connection of
field wiring.
The RTP3034SPG provides both a nonisolated and optional isolated
grounding connection to provide grounding for shield wires.
For control side protection applications, ERICO recommends the DIN rail
mount ERICO CRITEC Universal Transient Barrier (UTB) series.
3. MOUNTING
Mounting methods for the RTP include:
• Connecting to the spare port of the transducer
• Connecting in-line with wiring conduit
• "T" connecting to wiring conduit
For the "in-line" connection, the end cap, grounding wire, spring and
grounding disk should be removed. The electrical grounding connection
at the transducer should be made with field wiring to the center
(ground) terminal located at the LINE end of the protective module. An
optional isolated grounding connection can be made with shield wiring
at the transducer by connecting field wiring to the center (ground)
terminal located at the EQUIP end of the module.
Pipe adapters can be installed to connect to non-¾ NPT systems
