Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel.
No responsibility is assumed by Hubbell for any consequences arising out of the use of this material.
Installation 1. Turn off all power supplying this equipment before working on or inside
equipment.
2. For mounting, see Figure 1.
3. Confirm HBLSDSA36 is rated for your system by comparing voltage
measurements to the Line Voltage (L-L, L-N) on the product label.
4. Install in accordance with Article 285of the National Electric Code.
5. Confirm that the electrical terminals used to attach this device are
identified for these conductors.
6. Twist conductors 1/2 turn or more for every 12 inches of length.
7. Keep conductor length as short as possible with no sharp bends.
8. Ensure a high quality ground is in place.
9. Install cover and/or close door on equipment.
Diagnostic Operation
•LED ON = Normal Operation
•LED OFF = Fault, check phase voltage, breakers (if used) and
connections. If OK, replace unit. (see Figure 2)
