Electrical
Requirements
The unit construction provides protection against the risk of electrical
shock by grounding appropriate metal parts. The protection may not
function unless the power cord is connected to a properly grounded
outlet. It is the user's responsibility to assure a proper ground connec-
tion is provided.
The user is responsible to ensure that the power cord provided meets local
electrical codes. If not, contact qualified installation personnel.
The unit is intended for use on a dedicated outlet. The EX has an internal
circuit protection that is equivalent (approx.) to the branch circuit rating. This
is to protect the EX, and is not intended as a substitute for branch circuit
protection.
Power Cord Set
230 Volt, 50 Hertz units do not come with a power cord set, To select the
proper power cord, follow these guidelines:
The cord set must consist of a plug, cable and receptacle.
If the unit is rated greater than 12 Amps, use a cord set rated for 20A.
If the unit is rated less than 12 Amps, use a cord set rated for 15A.
The cord set must be approved by local electrical authority or other
acceptable agency.
Ensure the plug is compatible with your local outlets and receptacles.
Refer to the serial number label on the rear of the unit to identify the specific
electrical requirements of your unit.Ensure the voltage of the power source
meets the specified voltage, ±10%.
