Installation
Line disconnect switch
The line disconnect switch serves as the supply-voltage disconnecting (isolating) device. Install this
switch near the power supply for easy access by the operator.
Installation must be performed by a licensed electrician and according to applicable national and local
codes.
The switch should:
• Isolate the electrical equipment and disconnect all live conductors from the supply voltage when in
the “OFF” position
• Have one “OFF” and one “ON” position clearly marked with “O” (OFF) and “l” (ON)
• Have an external operating handle capable of being locked in the “OFF” position
• Contain a power-operated mechanism that serves as an emergency stop
• Have slow-blow fuses installed for the proper breaking capacity (see table on previous page).
Main power cable
Wire sizes vary based on the temperature rating of the cable insulation and the distance of the unit from the main box.
Use a 4-conductor Type SO input power cable with a conductor temperature rating of 60° C (140° F) or 90° C (194° F).
Installation must be performed by a licensed electrician.
