1 Safety rules
This manual contains all necessary information about the correct use of the VH Programming Board for a
firmware update of the Digital Energy™ VH Series. Before attempting to install or operate the equipment,
carefully read this manual. Keep this manual together with the User manual next to the UPS for future
references.
Full understanding of and compliance with the safety instructions and warnings contained in this

Please refer to the “Safety Rules” included in the “User Manual” of the UPS.
If any problems are encountered with the description of this installation guide, please
contact the nearest Service Centre before proceeding.
CAUTION!
These are sensitive electronic devices. Risk of electrostatic discharge!
Qualified, skilled personnel
are persons who (because of their training, experience, and position as well as their knowledge of appropriate
standards, regulations, health and safety requirements and working conditions) are authorized to be
responsible for the safety of the equipment, at all times whilst carrying out their normal duties and are
therefore aware of, and can report, possible hazards (observe IEC 60364 and national wiring regulations and

2 Introduction
Description
The Firmware Update must be performed using the Programming Board that is an option required when the
Digital Energy™ UPS VH Series model should be updated. The correct use of the Programming Board must
be performed with the using of an E8a Programmer and an External Power Supply adjusted between 4.75
and 5.8 Volt.
Do not attempt the Digital Energy™ UPS VH Series if all the necessary equipment is not available.

5 Remove dangerous voltage
CAUTION
To avoid damage due to ESD (ElectroStatic Discharge) be sure that maintenance work is
performed under ESD-safe conditions: work on an anti-static mat; ground yourself and the unit
when it is opened.
CAUTION
When the UPS is uncovered use the proper caution to not damage the board and all the
electrical parts.
• 1 Wait 10 Minutes to allow discharge of the DC-Capacitors.
Put a multimeter on the 2 indicated points to check if the capacitor is discharged.
(remaining voltage has to be less than <20V)
Use a 100 Ohm / 10 Watt resistor to discharge the capacitor on the correct indicated points how
shown in the picture.
