4.1. Mounting Instructions
Open the latch and lift the cover. Remove
the black caps located on each of the four
mounting holes. Mount the enclosure on
the wall using four screws. Be sure the
electrical knockouts are at the bottom of
the enclosure in order to prevent water from
entering the controller. Insert the screws in
the mounting holes and tighten. Fasten the
four black caps provided with the controller
onto the four mounting holes. The enclosure
must be mounted in a location that will allow
the cover to be completely opened right up
against the wall.
4.2. Connections
Refer to the wiring diagram enclosed with
this user's manual to connect the controller.
Use the electrical knockouts provided at the
bottom of the enclosure. Do not make ad-
ditional holes in the enclosure, particularly
on the side of the enclosure when using a
computer communication module.
All wiring must be done by an autho-
rized electrician and must comply with
applicable codes, laws and regulations.
Be sure power is off before doing any
wiring to avoid electrical shocks and
equipment damage.
Do not install rigid conduit into electrical
knockouts. Only nylon cable glands are
permitted for cable or wire fastening.
The controller has no power-on switch.
An external switch or circuit breaker
shall be included in the building instal-
lation to interrupt power to L and N
electric power lines. It shall be in close
proximity to the equipment and within
easy reach of the operator. It shall be
marked as the disconnecting device for
the equipment.
Note that the input terminals can be
taken off from the main board to make
the connections easier.
4.2.1. Probe Inputs
Probes operate at low voltage and are isolated
from the supply. Make sure that probe cables
remain isolated from all high voltage sources.
In particular, do not route the probe cables
through the same electrical knockout as other
cables. Do not connect the shield from the
probe cable to a terminal or a ground.
Extending a probe: Each probe can be ex-
tended up to 500 feet (150 meters).
To extend a probe: Use a shielded cable of
outside diameter between 0.245 and 0.260
in (6.22 and 6.60 mm) (the cable dimensions
should not be under 18 AWG) to ensure the
cable entry is liquid tight. Do not ground
the shielding.
It is preferable to solder the cable joint to
ensure a proper contact between the two
cables.
Do not run probe cables next to other
power cables. When crossing over other
cables, cross at 90°.
4.2.2. Alarm Connection
There are two types of alarms on the market.
One type activates when current is cut off at
its input, whereas the other activates when
current is supplied at its input. For an alarm
of the first type, use the NC terminal as
shown on the wiring diagram. For an alarm
of the second type, use the NO terminal.
