Rockwell Automation 1606-XL240-UPSE Power Supply Reference Manual - Manual (Page 18)

All parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.
It is assumed that the input power source can deliver a sufficient output current.

25. Installation Notes
Mounting:
The power terminal shall be located on top of the unit. An appropriate electrical and fire end-product enclosure should
be considered in the end use application.
Cooling: Convection cooled, no forced air cooling required. Do not obstruct air flow!
Installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left side are recommended when loaded
permanently with more than 5A. Do not place heat sources next to the 1606-XLS240-UPSE
since it can influence the function of rthe internal temperature sensor. Keep a minimum of
15mm from the adjacent device.
Risk of electrical shock, fire, personal injury or death!
Turn power off and disconnect battery fuse before working on the DC-UPS. Protect against inadvertently re-powering.
Make sure the wiring is correct by following all local and national codes. Do not open, modify or repair the unit. Use
caution to prevent any foreign object from penetrating in the housing. Do not use in wet locations or in areas where
moisture and condensation can be expected.
Service parts:
The unit does not contain any service parts. The tripping of an internal fuse is caused by an internal fault. If damage or
malfunctioning should occur during operation, immediately turn power off and send unit to the factory for inspection.
Wiring and installation instructions:
(1) Connect the power supply to the input terminals of the DC-UPS.
(2) Connect the battery to the battery terminals of the DC-UPS. Do not install the battery in airtight housings or cabinets.
(3) Connect the buffered load to the output terminals of the DC-UPS. The output is decoupled from the input allowing load
(4) Install the fuse upon completion of the wiring.

The battery should be installed according to EN50272-2, which includes sufficient ventilation. Batteries store energy and
must be protected against energy hazards. Use a 30A battery fuse type ATO® 257 30 (Littelfuse) or similar in the battery path.
The battery fuse protects the wires between the battery and the DC-UPS. It also allows the disconnection of the battery from
the DC-UPS which we recommend when working on the battery or DC-UPS. Disconnect battery fuse before connecting the
battery. Please note: Excessively long or short wires between the DC-UPS and battery may shorten the buffer time or result
in a malfunction of the DC-UPS. Do not use wires smaller than 2.5mm² (or 12AWG) and no longer than 2x1.5m (cord length
1.5m). Avoid voltage drops on this connection.
circuits to be easily split into buffered and non-buffered sections. Noncritical loads can be connected directly to the|
power supply and will not be buffered. The energy of the battery can then be used in the circuits that require buffering.
