Control panel (cont.)

Light A - emergency shutdown This red light signals that the remote "emergency shutdown" button was pressed (external information received and stored in memory).

Light B - rectifier-charger on

This green light indicates that the rectifier-charger is on.

Light C - rectifier-charger fault This red light is an alarm stored in memory signaling a rectifier-charger fault. It can signify one or several of the following faults:

input switch Q1 open;

RC input protection fuse (FU1-2-3) blown;

RC internal over-temperature;

battery charge over-current;

battery over-voltage;

RC electronic control board faulty, not calibrated or not personalized;

power supply board fault.

Light D - Mains 1 outside tolerances This yellow light signals that the Mains 1 voltage and/or frequency characteristics are outside tolerances.

Light E - battery room ventilation fault and/or harmonics filter temperature outside tolerances This yellow light is an alarm stored in memory signaling a battery room ventilation fault (external information that must be supplied from the room). If the installation includes a harmonics filter, this light will also signal an overtemperature of the filter’s inductor (information supplied).

Light F - battery temperature outside tolerances

This yellow light signals that the battery temperature is outside tolerances (external information supplied by special board ("Temperature Monitor" option).

Light G - battery charging

This yellow light signals that the battery is being recharged (vented batteries only). This light is deactivated in systems with sealed lead-acid batteries.

Light H - inverter fault

This red light is an alarm stored in memory signaling an inverter fault. It can signify one or several of the following faults:

inverter shutdown due to inverter output voltage outside tolerances;

inverter output protection fuse (FU5- 6-7) blown;

inverter stack subassembly protection fuse blown (parallel systems);

inverter leg fault;

inverter output transformer over- temperature;

inverter leg over-temperature;

phase or output voltage fault (parallel systems only);

internal clock fault;

inverter control board faulty, not calibrated or not personalized;

power supply board fault.

Light I - battery discharged

This yellow light signals that the battery has reached its minimum voltage level, resulting in inverter shutdown.

Light J - inverter desynchronized with Mains 2

This light signals that the inverter output frequency has been voluntarily desynchronized with that of Mains 2.

Light K - transfer to inverter function fault

This red light is an alarm stored in memory signaling a fault in the systems for load transfer from Mains 2 to the inverter. It can signify one or several of the following faults:

inverter output switch K3N fault;

parallel-connection relay fault (parallel systems only);

static switch internal over- temperature;

static switch ventilation fault;

static switch power supply fault;

transfer function control board fault;

inverter control board not calibrated or not personalized;

power supply board fault.

Light L - overload

This yellow light is an alarm signaling one or several of the following faults:

inverter stack current more than 5% above rated current;

inverter output current more than 5% above rated current;

Mains 2 line current more than 5% above rated current;

inverter shutdown due to current limiting of output current.

Light M - Mains 2 outside tolerances

This yellow light signals that the Mains 2 voltage or frequency characteristics are outside tolerances.

Light N - maintenance position

This yellow light signals that devices QF1, Q4S, Q5N and Q3BP are set to the maintenance configuration. The UPS system is not available for load protection.

Test connector

This 9-pin connector is reserved for after-sales support technicians.

It is used for connection to a microcomputer for:

system calibration;

personalization;

computer-aided diagnostics.
