Operation
Operation Modes
The manual bypass switch (Q601) offers the possibility of setting the system volt-
free when performing work inside the system, e.g. service and maintenance.
There is no interruption to the load when the switch is switched over. Two
positions are available:
• AUTO: In this position, the load is supplied by the UPS.
• BYPASS: In this position the load is supplied directly from the bypass mains.

Normal Operation
In normal operation, the manual bypass switch must be in the position AUTO.
During normal operation, the UPS supports the load with conditioned power.
While the UPS is in normal operation, the status LED Normal operation is green.

Battery Operation
In battery operation, the manual bypass switch must be in the position AUTO.
If the input source becomes unavailable or outside the specified limits, the UPS
transfers to battery operation and supports the load with conditioned power from
the DC source.
If the input source is recovered, the system is automatically transferred back to
normal operation.
While the UPS system is in battery operation, the status LED Battery operation is
yellow.
If the battery discharge limit is approached an alarm is activated. If the batteries
are depleted, the system transfers to bypass operation if the bypass source is
available and within tolerance. If the input source or the bypass source are still
unavailable, the UPS system will turn off and stop supplying the load, but if Auto
Start is configured for the UPS system, then the UPS will automatically restart and
return to normal operation again as soon as the input source is recovered.

Temporary Static Bypass Operation

In temporary static bypass operation, the manual bypass switch must be in the
position AUTO.
The UPS is in temporary static bypass following an event in the UPS system
(inverter inoperable, no input source available, no battery runtime available).
During temporary static bypass operation, the load is supplied by the bypass
source. When the cause of the automatic transfer is no longer present, the system
automatically transfers back to normal operation without interruption.
While the UPS system is in temporary static bypass operation, the status LED
Bypass operation is yellow.

Requested Static Bypass Operation

In requested static bypass operation, the manual bypass switch must be in the
position AUTO.
The UPS can be transferred to requested static bypass following a command from
the display. During static bypass operation, the load is supplied from the bypass
source. To avoid interruptions during the transfer, the voltage, frequency and
phase relation of the UPS system must be synchronized to the bypass source.

990–5731B–001 27
10–80 kVA Operation

The UPS will transfer to normal or battery operation if the bypass source becomes
unavailable.
While the UPS system is in requested static bypass, the status LED Bypass
operation is yellow.

ECO Mode
In ECO mode, the manual bypass switch must be in the position AUTO. The UPS
can be transferred to ECO mode following a command from the display or when
enabled the system will automatically switch to ECO mode after system has been
running for one minute in normal operation and the bypass voltage quality is
above the acceptable limits. ECO mode will transfer the system to static bypass
operation. In this operation mode the total system efficiency is increased. During
static bypass operation, the load is supplied from the bypass source. To avoid
interruptions during the transfer, the voltage, frequency and phase relation of the
UPS system must be synchronized to the bypass source. The UPS will transfer to
normal or battery operation if the bypass source becomes unavailable or if the
bypass voltage quality drops below the acceptable limits. While the UPS system is
in requested static bypass, the status LED Bypass operation is yellow.

Manual Bypass Operation

For repair and maintenance work or work inside the system, the manual bypass
switch must be set to BYPASS.
In manual bypass operation, the load is supplied with unconditioned power from
the bypass input via the manual bypass switch. The batteries are not available as
an alternate power source in manual bypass operation.

Charger Only
When the UPS is in charger mode, the UPS does not supply the connected load
with power.

Standby
When the UPS is in standby mode, the UPS is OFF and does not supply the
connected load with power, and the batteries are not charged.

OFF
When the UPS is in OFF mode, the UPS does not supply the connected load with
power, and the batteries are not charged.
