The connections are labeled within the terminal box and are self-
descriptive (see Figure 5).
•
Plugs are inserted into the alarm and 4-20mA/RS-485 cable glands when
shipped, to ensure a watertight seal. These plugs should be removed and
discarded when cabling to either of these connections.
• Maintain watertight seal. It is the owner’s and installer’s responsibility to
assure that the watertight seal is maintained after the terminal box has
been wired for operation. Failure to properly tighten any of the cable
glands around a cable or plug can create an electrical shock/electrocution
hazard.
3.4.1 Electrical Power Connection :
Make all connections at Junction Box and securely close BEFORE
making connections to a power source and energizing MTOL+.
ONLY
licensed electrician should perform the installation.
ALWAYS take proper precautions to recognize, evaluate, and control
electrical hazards.
a. First, make sure that MTOL+ is completely de-energized and
disconnected from all power.
b. Perform required LOCK OUT/TAG OUT of electrical power.
c. Confirm that a breaker or method of disconnecting power is located
within 2 meters (6 feet) of the MTOL+.
d. All of the electrical connections to the instrument are made through
the MTOL+ Junction Box (see Figure 5), which should be located
directly under the upper portion of the instrument.
e. Carefully open the MTOL+ Junction Box (see Figure 5) by removing
the four cover screws.
f.
With the Junction Box cover removed, the connections are visible
as shown in Figure 5.
g. The power cable glands will accept cable diameters from 5.8mm
(.230 in) up to 10 mm (.395 in.). All terminals are designed to
accept wires in the range of 12-30 AWG.
h. Obtain and cut proper wires to make connections for your specific
installation and facility. All wires should be stripped to a length of 6
mm (¼ in).
i. The connections are labeled within the terminal box and are self-
descriptive (see Figure 5).
