Functional Test
The functional test of the UPS should be performed every six months and include the following tasks:
-
Activate the manual bypass according to chapter 4 of this manual.
-
Disconnect the UPS according to chapter 4 of this manual and check
display and LED’s when restarting the
system as well as :
o
Correct start of the rectifier and inverter,
o
Function of the static switch,
-
Check the output voltages of the rectifier and the inverter as well as of the static Bypass and the battery charge
voltage.

Inspection of Battery
If the UPS is out of operation for a prolonged period, maintenance-free batteries, for example, must be recharged at
three-monthly intervals. Observe the instructions of the battery manufacturer!
The instructions for the battery are attached in the appendix of this manual.
CAUTION:
Acid vapour emitted in the battery compartment are corrosive and can cause injury upon contact with
the skin, eyes and when inhaled.
The applicable protective measures must be complied with in accordance with the safety regulations
of VDE 0510, Part 2.
When using an open battery the electrolytic level must be inspected. If it has reached its lower level, the battery must be
refilled with distilled water according to DIN 43530 part 4. The battery must be kept clean and dry in order to prevent
leakage current. Plastic-components of the battery, especially the cell compartments, may only be cleaned with pure
water. Every three months the measuring and logging shall include the following:
-
Battery voltage, if possible the voltage of each cell / block
-
(If applicable)The electrolyte temperature of the block batteries.
If applicable, the following items must be checked and logged every year according to DIN 43539 part 1 and special
inspections are to done according to VDE 0108:
-
Density of electrolyte
-
Voltage of all cells / blocks of battery
-
Quality of bolted fastening
Additional checks with automatic test equipment are not permitted, except the written approval of the battery manufac-
turer.

NOTE:
In case the battery voltage is out of tolerance and/or charging is not successful, the
JOVYATLAS
-Service should be contacted.

Environmental Temperature (Operation)
The temperature-correction factor for calculating the capacity of the battery is set to 0.006 if the battery-manufacturer
does not specify a different value (see also chapter 18.8 IEC-Draft-896-2).
