1. Safety Instructions and Waste Disposal Rules

Warning!

Because several components of operating electrical modules are charged by dangerous voltage, the

improper handling of electrical modules may be the cause of accidents involving electrocution, injury,

or material damages.

Operation and maintenance of electrical modules must be performed by qualified skilled

personnel such as electricians in accordance with EN 50110-1 or IEC 60950.

Install the module only in areas with limited access to unskilled personnel.

Before starting work, the electrical module must be disconnected from mains. Make sure that

the module is earthed.

Do not touch connector pins as they can be charged with dangerous voltage up to 30 seconds

after disconnection.

Only spare parts approved by the manufacturer must be used.

All electric modules must be disposed of separate from domestic waste at collecting points that

have been set up by the government or municipal authority.

“Separate collection is the precondition to ensure specific treatment and recycling of WEEE and is

necessary to achieve the chosen level of protection of human health and the environment in the

Community.”

The above statement from EU directive 2002/96/EC applies to all electric modules installed within

EU countries.

In countries outside the EU, different rules may apply regarding waste disposal of electric modules.

For more information about waste disposal of your discarded equipment, contact your

ELTEK VALERE INDUSTRIAL partner.

2. General Information

The static transfer switch STS118 is designed for a nominal switching capacity of 18kVA and is

used for nearly interruption free switching (<4 ms) between two AC sources (usually inverter and

substitute-mains supply). It is intended for operation in combination with inverters of series

INV215/222. Consequently AC consumers can be driven nearly without interruption if one of the two

power sources fails. All operation and indication elements as well as an Ethernet connector are user-

friendly integrated in the front plate of the unit.

The STS118 is a hot plug-in module with rear side connectors and is designed to be mounted in an as-

sembly set sub rack (see section 3.2). A maximum of eight INV222 (two fully equipped AC power racks

ACR INV222-9.0) can be connected to the STS118.

2.2 Operating modes

The static transfer switch STS is designed for the operating modes “inverter priority” and

“mains priority”. The consumer load is energized by the priority source if the operating system works

under fully functional conditions.

2.2.1 Inverter priority configuration

In the operating mode “inverter priority” the load is switched on inverters during normal operation.

This is the standard configuration (factory setting).

Source “Mains” only is required to energize the consumer load if source “Inverter” fails or is overloaded

(i. e. distortions by short circuit behaviour or overload).

The priority source is programmable via the service menu.

2.2.2 Mains priority configuration

In the operating mode “mains priority” the AC mains works as priority source and the inverter

(as “substitute mains”) as source 2.

3.4 Electrical connections

All electrical connectors such as AC inputs and outputs, DC supply, CAN-Bus, synchronous bus and signals are fitted on the rear side of the module. A sub rack

with backplane is necessary to connect the module to the system. The rear side connections of the backplane are shown in figure 3) and defined in the table

“Assignment of the rear side backplane connectors” on the next page.
