Only competent personsshould replace the fuse.

AC fuse (F2,F3)

Littelfuse

215; AC 250V, 3.15A, 5×20mm, rated

breaking capacity: 1500A

WARNING

Risk of electric shock –Both A.C. and D.C. voltage sources are

terminated inside this device. Each circuit must be individually

disconnected before servicing.

WARNING

Hot surfaces –To reduce the risk of burns –Do not touch device

surface when the device is running.

Allow 30 minutes cooling down period after switch off before

handling the device.

WARNING

Risk of electric shock from energy stored in capacitor! Do not

remove cover until 45 minutes after disconnecting all sources of

supply.

WARNING

The printed circuit boards contain components sensitive to

electrostatic discharge. Wear a grounding wrist band when

handling the boards. Do not touch the boards unnecessarily.

WARNING

Do not operate device if found to be damaged or lacking parts.

WARNING

Before installing the unit, obtain approval from the utility

company.

WARNING
