Å
(ac) and above configuration. In phase-to-neutral, 100 V
Å
(ac) and
above applications, L2 is neutral and must not be fused or switched. Failure to follow this guideline could result in personal injury or

NOTE:
Grounding
•
Use a grounding conductor
terminal plate (fork terminal)
having upturned lugs or the
equivalent to hold the wire in
position. Maximum 6 mm
2
(10
AWG) wire.
Fusing
•
Recommended fusing options (see
page 6) to meet 200KA SCCR, type
1 and 2 approved. All other fuse
and SCR combinations are defaulted
to 5KA SCCR per UL508A and NEC
guidelines.
Torque Guidelines
• Properly torque line and load
terminals to 1.4 Nm (12 in-lb).
• Retorque after 48 hours to
minimize wire cold flow.
• Retorque line and load terminals
every 3 to 6 months.
