Electrical Wiring

To reduce risk of SEVERE INJURY or DEATH to persons:
• All electrical wiring should be done by a qualified professional and in accordance to local
electrical codes.
• Always shut OFF the main power before performing any electrical intervention.
• Use proper wire gauge for incoming power line and for accessory connections.
• Install operator main circuit breaker next to operator for easy access for power shut-off.
• Use separate knockouts on operator control box for accessories and main power cables.
• Always separate low and high voltage wires.
• Operator should be properly grounded to the building ground and to the main power
supply ground lug.
• Always use suitable and appropriate rating circuit breakers for operator protection.
• Compare available power supply voltage to voltage on operator name plate prior to
electrical connection. Failure to connect appropriate power supply voltage may cause
serious damage to the operator.
• THE OPERATOR MUST BE ADEQUATELY PROTECTED AGAINST OVERCURRENT AND SHORT-
CIRCUIT.
• PLEASE REFER TO LOCAL ELECTRICAL CODE.
• PLEASE REFER TO NATIONAL ELECTRIC CODE (NFPA 70) ARTICLE 430 SECTION IV (430,51 /
430,52 / 430,53).
• PLEASE REFER TO CANADIAN ELECTRIC CODE (CSA 22,1) SECTIONS 28-200 / 28-206.
Guideline to determine the branch-circuit rating of the protective device [A]:
Time Delay Fuse: 1,75 x FLA
Non-Time Delay Fuse: 3,0 x FLA
A fuse that does not exceed the next higher standard ampere rating shall be permitted.
Example: If FLA = 3,8A
Time Delay Fuse: 1,75 x 3,8A = 6,65A → Standard fuse to use: 10A
•
Non-Time Delay Fuse: 3,0 x 3,8A = 11,4A → Standard fuse to use: 15A
•
