Installation
If the remote sensor is not easily accessed, it is best practice to install tubing that can be used to
apply calibration gas from the device display. Route the tubing to the remote sensor, ensuring that
there are no kinks, leaks or other obstructions. Secure this tubing near the monitor.

3.4.1 Electrical Warnings - Read before Connecting Power
WARNING!

Before wiring the TG5000 transmitter, disconnect the power source supplying the transmitter to
ensure no electrical shock could occur.

Install wiring in accordance with the electrical code of the country in use, the local authority
having jurisdiction and these installation instructions, as applicable.

Do not make any connections to the TG5000 main board or junction box input, output, and relay
connections while under power. Making connections under power could lead to electrical shock
or ignition of a hazardous atmosphere.

Ensure that water and dirt are not able to enter the unit via the wire or conduit. If the unit is
installed in a location known to be wet or damp, it is good practice to loop or bend the entry
into the unit that prevents water incursion.

The internal grounding terminal located in the base of the transmitter enclosure must be used
for equipment grounding. The external grounding terminal is only to be used as a supplemental
bonding connection where local authorities permit or require such a connection.

