Locate the RTU as close as possible to the 

control cabinet while considering the antenna 

cable length. 

Warning:

 Turn off station power to 

avoid damage to mainboard.

Note:

 MyDro units should be connected 

to a LPS-certified power supply (12 VAC 

60 Hz 

~

 or 12 VDC           ).

1.  Mount the enclosure.

2.  Cut the conduit and wiring holes. Drill and 

attach the conduit in the control cabinet 

and Mission RTU. Use sealant where 

appropriate. 

3.  Pull the wires and cables. 

4.  Ground the RTU. Use 12 to 14 gauge 

green wire to connect the grounding lug 

on the backplate in the RTU to the stations 

Earth ground (refer to Figure 1). 

Note:

 If using the Safe Module Plus 

for sensing the high-level float in an 

intrinsically safe manner, install it now. 

Refer to the MyDro Expansion Module 

Installation Manual for more information. 

5.  Terminate digital inputs. Refer to the 

wiring diagram on the M150/M850 cover/

door and the RTU Installation Form in the 

packing box. Record input names on the 

setup form and the diagram.
