ALERT
ALERT! Only use components and crimping tools approved by agencies or certifying bodies recognized in
your country or region such as Underwriter’s Laboratories (UL), TUV, etc.
5. For ground wiring, use a listed (approved) crimping tool to attach
a listed (approved), single- or dual-hole compression lug (dual
hole is highly recommended) suitable for a #10 stud (~5 mm) on
⅝-in. (15.9 mm) centers onto a suitable ground wire. (Ground
wire can be up to #6 AWG for a dual-hole lug. Conductor size
depends on input interruption device.)
6. Use a coarse, nonmetallic cleaning pad to clean the terminals
and stud(s).
7. Telect recommends that you lightly coat antioxidant on the lug,
grounding screw(s) and surrounding contacting surface.
8. Connect the lug to the rear panel using the #10 screw(s)
provided, as shown in Figure 7.
