In combination with the UEI 710 changeover and monitoring device, the motor-driven switch-disconnectors form the automatic changeover in accordance with DIN VDE 0100-710 (VDE 0100 Part 710). The switch-disconnectors meet the criteria of reliable disconnection.
The switch-disconnectors are electrically interlocked so that it is prevented that both supply lines are connected unsynchronized.
The UEI-710-V.5 is a multifunctional switching and monitoring device for IPS according to DIN VDE 0100-710 (VDE 0100 Part 710) or IEC 60364-7-710 in medical applications.
Monitoring:
All operating or fault messages are indicated via LEDs and full graphic display. Two integrated digital outputs and external coupling relays allow connection to the building management system (BMS).
Insulation fault detection system:
In conjunction with insulation fault detectors (e.g. IFS-710-W6), the UEI-710-V.5 represents a complete insulation fault detection system. The UEI-710-V.5 controls the insulation fault search (with integrated test current generator) and outputs output circuit-related fault messages.
Automatic switch-over:
In conjunction with motor-driven switch-disconnectors, the UEI-710-V.5 is an automatic switch-over and monitoring device in accordance with the German regulations:
The switching between the supply lines of the general and the safe power supply (AV / SV) or the battery-supported and the safe power supply (BSV / SV) takes place within 0.5 seconds.
2-pole miniature circuit breakers to protect the output circuits against overload and short-circuit in accordance with DIN VDE 0100-430 and DIN VDE 0100-530. If a second insulation fault occurs within the IPS, the miniature circuit breaker ensures fault protection (protection against indirect contact) in accordance with DIN VDE 0100-410. 16A miniature circuit breakers with B characteristic and 10kA breaking capacity are used as standard.
The following transformer sizes require the use of miniature circuit breakers with lower rated currents:
3.15 kVA: 10A miniature circuit breaker
4.00 kVA: 13A miniature circuit breaker.
The isolating transformers of the TRAK series meet all requirements of DIN VDE 0100-710 (VDE 0100 Part 710) for IPS in medical applications.
In isolating transformers, the secondary side is electrically isolated from the primary side. They have reinforced insulation and meet the requirements of DIN EN 61558-1 (VDE 570 Part 1) and DIN EN 61558-2-15 (VDE 0570 Part 2-15).
In order to reduce electrical interference, there is a static shield between the windings with an insulated connection leading out for connection to equipotential bonding. The corrosion protection is ensured by a complete vacuum resin impregnation. This measure also ensures low noise emission, even after long periods of operation.
General technical features:
In addition to the standard version, the ECO version is also available. The ECO transformers are particularly characterised by their lower power dissipation and lower inrush current, which means that the upstream fuses and thus also the supply lines of the IPS distributors can be reduced.
The UEI 710 Automatic Changeover Device can be disconnected from the two supply lines via the feed load disconnectors, without these having to be disconnected in the upstream distribution boards.
The feed load disconnectors enable a bypass function to be carried out.

The IFS-710-W6 has 6 integrated current transformers and is used to detect insulation faults in IPS. For this purpose, the IFS is installed on a DIN rail behind the circuit breakers of the outgoing feeders and thus monitors all assigned individual circuits.
Advantages
Principle sequence of an insulation fault search:
The multifunctional changeover and monitoring device UEI-710-V.5 constantly monitors and determines the insulation resistance in the entire IPS. If the insulation resistance falls below a specified value, the search process is started by the integrated test current generator of the UEI-710-V.5. The test current generator feeds a test signal into the IPS. The insulation fault locator IFS-710-W6 uses its current transformers to detect the test signal in the faulty output circuit and reports it to the UEI-710-V.5 via CAN bus. This evaluates the fault locator and transmits the evaluation to the CAN bus. The evaluation can be output as individually configured messages on the peripheral display devices.
The information on the faulty circuit is stored in the integrated message memory and can be used for later evaluations.

Switch for implementing the bypass function in combination with upstream feed-in switch-disconnectors. The supply line used for the bypass is defined in advance (preferred supply line). When switched on, the changeover direction is bridged and the preferred feed line supplies the IPS transformer directly.
The bypass switch is used for testing the changeover device without voltage interruption on the outgoing feeder line to be supplied and for voltage-free replacement of the devices during operation. An LED is used to indicate the switching status of the bypass switch.
If the bypass switch is used, the available space for miniature circuit breakers is reduced. There are 6 less outgoing circuits available.
Bypass clamping system (3x3x35/25mm²) for the realisation of the bypass function in combination with upstream load disconnectors. The supply line used for the bypass can be selected as required (preferred or alternative supply line).
The bypass clamping system is used for testing the changeover device without voltage interruption on the outgoing feeder line to be supplied and for voltage-free replacement of the devices during operation.
The bypass clamping system does not reduce the number of outgoing circuit breakers that can be installed.
