User manual LP11 924 6 & 10 kVA UPS 1.0

After 24 hours of charging time, the battery voltage did not reach the normal float
voltage. This may be caused by faulty batteries, too many battery packs connected or

a charger fault.

BATTERY CHARGERY
NO FLOAT

The main DC-capacitor needs replacement due to aging or failure.

CAPACITOR C1
CAPACITY LOW

Due to a failure the output converter's output is not available. As a result the load may
have been transferred to bypass.

LOADnotPROTECTED
INVERTER OFF

The remaining runtime is zero. As a result the load may have been transferred to

bypass.

LOADnotPROTECTED
BATTERY DEPLETED

The remaining run time is less than the set time (standard 2 minutes). This text

alternates with the following screen:

LOADnotPROTECTED
BATTERY LOW

UPS SHOUTDOWN
LEFT 2 MINUTES

The output voltage can be lost after the indicated time due to discharged battery.

Controlled shutdown of any computer equipment is absolutely necessary at this point.
(Using the RS232 or SNMP communications interface, this procedure can be initiated

automatically on unattended systems). If the UPS operates at 100% load, the

shutdown procedure should be completed within 2 minutes after the 'battery low'
alarm started. When the batteries are fully discharged, the UPS is no longer able to

power the connected equipment.

The static bypass circuit breaker (rear panel, 9) is in 'off' (down position): no bypass

voltage available. Utility voltage is available. If not manually operated, this may have
been caused by an overload situation.

BYPASS ERROR
FUSE FAILURE

The utility circuit breaker (rear panel, 8) is in the 'off' (down position): no line voltage
available, bypass voltage is available. If not manually operated, this may have been

caused by an internal system failure.

INPUT ERROR
FUSE FAILURE

The internal battery fuse is defective; this may have been caused by an internal system

failure. This alarm also appears if no batteries are installed.

INTERNAL BATTERY

FUSE FAILURE

The external battery has been disconnected from the system: its energy reserve is not
available. See section 4.5.5 step 7 for details.

EXTERNAL BATTERY
FUSE FAILURE

The batteries are (almost) chemically worn out. If the batteries are aged, they must be
replaced as soon as possible to ensure full protection for your equipment (see section 8.4).

REPLACE BATTERY

The utility voltage and/or utility frequency are outside UPS input tolerance (see chapter
10, specifications).

INPUT out LIMITS
137V 60.0Hz

The utility voltage and/or utility frequency are outside bypass input tolerance but
inside UPS (rectifier) input tolerance (see chapter 10, specifications). Bypass operation

is inhibited: if for whatever reason the output converter is unable to deliver the
required output, output power is lost.
