1)
Conduit sharing rules were determined through EMI and shared conduit testing. These rules indicate wiring methods that have
no adverse affect on the proper operation of the equipment, but do not necessarily indicate compliance with local codes.
2)
Check local codes concerning wire gauge and distance to extend the 3-foot pre-determined “Fan Output” cable. The 3-foot
cable is No. 18 AWG.
