Battery Set for UPS 60, Order No. 77 3450 00<br />
The battery set for UPS 60 are rechargeable batteries (= accumulators) that build an uninterrupted<br />
power supply (UPS) in combination with the power supply unit UPS 60, order no. 77 3400 10.<br />
If the mains input voltage fails or when it drops to less than 90 VAC, the two lead-gel batteries will<br />
continue to supply the users connected to the power supply unit UPS 60 without any interruption.<br />
Safety instructions<br />
1. Mounting<br />
• The battery set may only be used together with the power supply unit UPS 60, order<br />
no. 77 3400 10. The safety instructions delivered with this power supply unit have to<br />
be observed as well.<br />
• The power supply unit UPS should only be installed and commissioned by qualified<br />
specialists.<br />
• Before effecting any work at or with the power supply unit UPS, it must be isolated<br />
from any input voltage and the battery fuse (located between the batteries) has to be<br />
removed.<br />
• Always watch for the safe isolation of AC and DC circuits!<br />
• Observe the general safety instructions for the handling of batteries! Sufficient<br />
ventilation must be provided to preclude the development of an explosive hydrogenair<br />
mixture!<br />
• If the battery set for UPS 60 will not be used for a longer time, first the batteries have<br />
to be fully charged. After that the batteries must be disconnected from the mains<br />
supply. This can be done by disconnecting the battery connection cable from the<br />
power supply unit UPS 60 (see chapter 2.). Alternatively the battery fuse can be<br />
removed.<br />
The battery set for UPS 60 is designed for wall mounting. Bore holes are prepared at the housing for<br />
fixing the unit at the wall – preferably under the power supply unit - using the enclosed mounting<br />
material. A dimensional drawing is shown on the next page.<br />
Before mounting, check the condition of the wall itself.<br />
The battery set for UPS 60 weighs approx. 25.2 kg.<br />
The unit must be mounted such that the venting ports are at the top and bottom.<br />
The selected location must ensure sufficient air circulation above and below the unit. Therefore, check<br />
for minimum distance of 50 mm to walls, ceiling and other equipment. The venting ports must not be<br />
covered up. Insufficient air circulation may lead to damage to the power supply unit.<br />
