When using the CB-37F-HVD with hazardous voltages (>30 Vrms, 
42.4 V

pk

, 60 VDC), it is required that all signal wires must be strain 

relieved, and the CB-37F-HVD must be placed in a UL listed, 
suitably-rated NEMA or IP enclosure, shown in Figure 1, which is 
grounded to a safety earth ground. The enclosure must be entirely enclosed 
and none of the parts should be accessible to the user when the system is 
running.
