Power supply unit UPS 60
The power supply unit UPS 60 is a power supply unit and includes the electronics that builds up an
uninterrupted power supply (UPS) in combination with battery set for UPS 60 (order no. 77 3450 00).
Input voltage of 115 - 230 V AC is transformed into 24 V DC output voltage. The UPS feature ensures
the supply of the connected DC users also in case of a mains power failure.
If the mains input voltage fails or when it drops to less than 90 VAC, the two connected lead batteries
will continue to supply the users without any interruption.
To protect the batteries from going flat, circuit breakers will open when during the UPS mode the
output voltage drops below to 19.5 V. When the mains supply voltage is active again, the system
reverts to its normal operating mode.
Roughly, every 15 minutes, an integrated test circuitry performs a voltage check at the battery
terminals, the connections and at the circuit breakers. Upon the return of the mains supply current, the
battery is isolated from the outputs, and the internal charging module recharges the battery.
Safety
The device has been constructed according to the latest valid regulations governing technology and is
operationally reliable. It has been tested and left the factory in a technically safe and reliable state.
However, residual hazards remain. Read and adhere to the safety instructions to prevent hazards of
this kind. Tunstall GmbH accepts no liability for any failure to observe the safety instructions.
Target group / Qualifications of personnel
Installation, commissioning and maintenance of the device must only be carried out by trained and
properly qualified electrical installers.
The electrical installer must have read and understood the manual and follow the instructions
provided.
The electrical installer must adhere to the valid national regulations in his/her country governing the
installation, functional test, repair and maintenance of elec-trical products.
The electrical installer must be familiar with and correctly apply the "five safety rules" (DIN VDE 0105,
EN 50110):
1. Disconnect the power
2. Secure against being reconnected
3. Ensure there is no power
4. Connect to earth and short-circuit
5. Cover or barricade adjacent live parts
Safety instructions
•
Electrical systems may only be constructed, extended, modified and maintained by
an authorised group of personnel.
•
The power supply unit is intended for the use in an operating area with
restricted access.
•
The power supply unit is suitable for mounting above a non-combustible
surface only.
•
Work must only be carried out when the system has been disconnected from the
power. Before starting installation and service work, the input voltage must be
disconnected and secured to prevent it being reconnected. Failure to observe this
may result in persons touching live parts or experiencing serious injury.
•
The supply voltage must be connected in accordance with the regulations that apply
in the country concerned (in Germany's case, these are VDE 0100 and VDE 0160).
•
Protective and isolation equipment for disconnecting the input voltage must be
provided.
•
If the values specified in the technical data are exceeded, there is the risk of the
device overheating, which may result in the supply voltage device being destroyed
and the electrical safety being impaired.
•
Safe isolation of the AC and DC supplies must be ensured at the premises.
•
General safety instructions on handling batteries must be observed. In par-ticular, it
