WARNING
Risk of electrical shock, fire, personal injury or death.
- Turn power off before working on the device. Protect against inadvertent re-powering.
- Do not modify or repair the unit.
- Do not open the unit as high voltages are present inside.
- Use caution to prevent any foreign objects from entering the housing.
- Do not use in wet locations or in areas where moisture or condensation can be expected.
- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.
Obey the following installation instructions:
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to the factory for
inspection.
Turn power off and disconnect the battery fuse before working on the device.
Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN-rail according to EN 60715 with the battery terminals on the bottom of the unit.
The input can be powered from a regulated power supply or a similar DC source. Use an appropriately sized power supply, which can
deliver the additionally required internal current consumption of the DC-UPS and the required current for charging the batteries. If a
power supply with a continuous output current greater than 50A is used, a fuse with 63A B- or C-Characteristic must be connected
between the power supply and the DC-UPS. The continuous voltage between the input and ground must not exceed 60Vdc. The input
must be powered from a PELV or SELV source or an “Isolated Secondary Circuit” in order to maintain a SELV or PELV output.
Check for
correct input and battery polarity. The device will not operate when the voltage is reversed.
Use only VRLA lead acid batteries with a capacity between 12Ah and 200Ah.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that are designed for a
minimum operating temperature of 60°C for ambient temperatures up to +45°C, 75°C for ambient temperatures up to +60°C and 90°C
for ambient temperatures up to +70°C. Ensure that all strands of a stranded wire enter the terminal connection.
Do not use wires smaller than 6mm
2
(AWG 10) and not longer than 2x1m between the power supply and the DC-UPS controller. Longer
or smaller gauge wires can cause malfunctioning of the system.
Do not use wires smaller than 6mm
2
(AWG 10) and not longer than 2x1.5m between the battery and the DC-UPS controller. Longer or
smaller gauge wires can change performance of the system.
Use two fuses each 35A or 40A in parallel (ATOF® 287 035 or ATOF® 287 040 from Little fuse or an UL listed fuse with the same
characteristics) in the battery circuit. The battery fuse protects the wires between the battery and the DC-UPS and shall be located close
to the battery.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed.
T
he device is designed as “Class of Protection III” equipment according to IEC 61140.
