no: The difference is probably due to distortion of the mains
voltage (the inverter voltage is an almost perfect
sinewave)
Continue with G
yes: Continue with G
G: Static Switch Commutation Check • C
OMMUTATION TO THE BYPASS
Press the pushbutton on the CPHC16-S pcb for the bypass.
The static switch SSB will switch on and SSI will switch off, as
indicated on the front panel and on the SS/FY pcb (red LEDs).
• C OMMUTATION TO INVERTER
Press the pushbutton PB3 at the bottom of the ICP pcb. The
static switch SSI will switch on and SSB will switch off, as
indicated on the front panel and the SS/FY pcb (green LEDs).
H: Battery Charging Current Limitation
Check • Connect the load and open IRP.
The load is now supplied only by the batteries.
• Discharge the batteries for about 2 minutes at nominal UPS
load or longer if the connected load is smaller than nominal
UPS load
• Close IRP again.
• After 30 seconds, measure the battery voltage.
? Is the battery voltage lower than the set floating charge voltage?
no The rectifier is not yet in battery current limitation. In order to check
the battery current limitation you must discharge the batteries for a
longer period.
• Return to H.
yes The battery current limitation can now be checked according to the
battery installed. Standard setting is 10% of the battery capacity.
• Measure the battery recharging current with a dc clip-on amme-
ter.
? Is this approximately 10% of the battery Ah capacity?
no Check the settings of the dipswitch S1 on the CPHC16 -R pcb for
the rectifier according to JUE400899 programming of PCBs (V2.0
or later). Otherwise, the battery charging current may need to be
adjusted using the RS232 connector on the CPHC16-R pcb and a
portable computer. This must be performed by first discharging the
battery by switching off IRP, connecting the PC and adjusting the
charging current. The battery must remain connected through-
out the procedure.
• Return to H.
yes T HE S TART -U P PROCEDURE HAS BEEN SUCCESSFULLY COMPLETED NOW .
