This replacement device will be sent either in advance or after prepayment of the value of the replacement device and the costs of delivery, or after receipt of the defective device.

If TENKA POWER has decided to request from the warranty claimant the prepayment of the value of the replacement device or the assembly before delivery of the replacement device or the assembly, TENKA POWER will refund to the warranty claimant the amount received by the warrant claimant as prepayment of the value of the replacement device or the assembly once the warranty claimant has returned to TENKA POWER the defective device or the defective assembly, the defective device or defective assembly has been received by TENKA POWER and this defective device or defective assembly does not have any further defects not previously made known to TENKA Power.
Should the warranty claimant return the defective device or the defective assembly more than fifteen (15) working days after receipt of the replacement device or the assembly, then TENKA POWER has the right to charge the warranty claimant for the cost of administering the overdue Return Material Authorization (RMA) account. Return items will not be accepted without a valid RMA number obtained from TENKA POWER that is clearly displayed on the returned items packaging.
Specific Information on the Coverage of Other Costs
TENKA Power will inform the warranty claimant of any costs (including, but not limited to transportation, replacement device value, export certifications, inspections, customs duties, travel, or accommodation) that require payment in advance of the repair action. The repair will be performed depending on the warranty claimant’s consent to cover these costs.
