STEP 2 - Mount the Controller
IMPORTANT
: The 3D TRASAR controller is
designed to meet NEMA4X standards for weather
resistance. It is recommended that the unit be
installed in a sheltered area to minimize the
chance of water or debris entering the enclosure
when the cover is opened for wiring and mainte-
nance.
In order to maintain the NEMA 4X rating:
• Unused cord grips must remain plugged.
• Enclosure cover must be tightly closed at
all times.
• Ethernet port cover must also be in place
when this port is not in use.

2.2.1 General Instructions
1. Avoid installing the 3D TRASAR controller close to any high voltage source(s), large motors,
or any known generator of electrical and strong magnetic noises.
2. The mounting location should be well lit and dry.
3. If mounting outside, provisions must be made to protect the controller from direct sunlight
and driving rain.
4. In cold weather climates, provisions must be made to prevent piping from freezing.
5. The mounting location should be accessible to sample water (5 gpm minimum) and an
electrical power source (20 amp circuit at 85-250 VAC).
6. If using the bio-reporter Pellet Feeder, install it on the right hand side of the 3D TRASAR
controller (as you face the controller) within 10 ft.
a. The Pellet Feeder is electrically connected to the 3D TRASAR controller with a 25 ft.
pre-configured cable. If necessary, this cable can be spliced in the field to lengthen it
to a maximum of 100ft.
b. The Pellet Feeder should be plumbed to the bottom 3/4” sensor outlet piping of the
3D TRASAR controller off the right side of the panel (Refer to Section 2.4.3).
7. If using liquid bio-reporter, mount the feed pump in a location convenient to the bio-reporter
tank and the 3D TRASAR controller.
8. Chemical feed pumps should also be mounted conveniently to the 3D TRASAR controller
and chemical feed tanks.
