WARNINGS:
Ó
1
WARNING: Use National Electric (NEC) or other country-specific standard wiring practices to install and operate the DIN-A-MITE.
Failure to do so may result in damage to equipment and property, and/or injury or loss of life.
Ó
2
WARNING: Wiring examples show L2 in phase-to-phase, 200 V
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
death.
Ó
3
WARNING: Only authorized and qualified personnel should be allowed to install and perform preventive and corrective maintenance on
this unit. Failure to do so could result in damage to equipment, and personal injury or death.
4 WARNING: Hot surface, do not touch the heat sink. Failure to follow this guideline could result in personal injury.

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.
