Section 3: Wiring
3.1 Hazardous Location Safety:
See drawing CI-35152-XP or CI-35152-IS for all Hazardous Location installation safety information.
3.2 Proper Grounding:
Conduit is not an acceptable form of grounding.
Proper grounding is required in hazardous locations to prevent damage to the equipment and the
following:
•
electrical faults to ground
•
accumulation of electrostatic charges
•
atmospheric discharges
The JMT is supplied with both an external and internal earth grounding screw. Either of these
screws can be used to properly ground the device.
3.3 Recommended Loop Wiring (Diagram)
BEST PRACTICE:
All JMT Transmitters come with the UPPER
housing conduit entry plugged as shown in
image below. (Second entry is plugged with
temporary plastic NPT plug.) It is best practice
to connect conduit via lower available entry to
prevent water ingress. In the even unit is
flipped in field, Jerguson recommends
switching the plug to follow this orientation.
