B) 

The MCP should be mounted at least 5 feet outside of the swept area of the fan blades; 

this will allow safe operation of the fan and still provide access to the MCP when the fan is 

running. 

C) 

Be sure to keep the lockable service disconnect located on the side of the MCP within 

line of sight of the fan motor to comply with OSHA and local safety codes. 

D) 

Mount the MCP, making sure the enclosure is firmly fixed to the mounting surface. 

Step 5

, Mount Remote Switchbox

Select a location for the remote switchbox and mount securely. 

A) 

The remote switchbox should be no more than 100 feet away from the MCP. 

B) 

Mount the remote switch box in a location that is easily accessible for personnel 

authorized to operate the fan. 

C) 

Locate the switch box in an area where it will be safe from damage caused by 

unintended contact. 

D) 

Securely mount the remote enclosure, making sure it cannot be easily detached by 

incidental contact. 

Step 6

, Make Control Circuit Connections

A) 

Strip cable and conductors at both ends. 

B) 

Install one supplied strain relief fitting in the remote switchbox and make appropriate 

connections, referring to the wiring diagram (on page 28) packaged in the control panel 

and/or the sticker inside the remote enclosure.  Close up the remote enclosure. 

C) 

Install the other supplied strain relief fitting in the MCP enclosure and make control circuit 

connections at the terminal strip of the VFD located inside the MCP, see included wiring 

diagram (on page 28).  Do not make any incoming power or motor lead connections at 

this time. 

D) 

Ground the shield of the control circuit cable to the ground screw located in the lower 

left corner of the VFD next to the MAINS terminal. 

E) 

Daisy chain additional controllers if used, see included wiring diagram (on page 28).  

Ground the shielding of the cable at the slave controller side only.  There is no need to 

specifically designate a “Master” drive — any drive may be used as either a master or 

slave with no changes.  If interfacing with any kind of automated building management 

system, however, please consult factory as there may be additional programming 

required. 

F) 

Route the control circuit cables away from all incoming power and motor cables, 

keeping them separated by at least 6 inches.  When control circuit wiring must cross 

power cables, make sure they do so at 90 degree angles to minimize interference. 

Step 7

, Make Motor Lead Connections

A) 

Verify controller voltage; this can be found on the lower left corner of the MCP, as well as 

the sticker on the side of the VFD (see “input”).
