If for some reason the output voltage is reduced by less than 90% of nominal) these lines open. The major advantage to the PWR-240 REDs redundant power supply is that if a single power supply fails, it can be replaced by qualified personnel without shutting down the system, (hot-swap).
Since the PWR-240 REDs utilizes two 24 Vdc 10 A power supplies in parallel, they divide the required current evenly and so can provide up to a combined 20 A without going into an overload condition.

OUTPUT PROTECTION After time (t) in seconds, the MCB opens, interrupting supplied power according to the following table: CURRENT (A) MCB TIME TO TRIP (S) 14.5 16.8 19.2 21.4 The overload condition must be resolved and the MCB must be manually re-armed to restore normal operation.
Optional 12 Vdc Power Block for RFID Applications Mount the 12 Vdc Power Block inside the cabinet, prepare the AC cord and con- nect it to the AC input terminals as described in " 12 Vdc Power Block Installation (Optional)" on page 14 PWR-240 REDS...
PWR powers up correctly. On each supply the green DC-OK light should be on steady and the overload light (red) should off. 7. Close and lock the PWR enclosure and check that it does not open (lock functions correctly). The PWR-240 REDs installation is now complete. INSTALLATION MANUAL...
IMPORTANT: The cabinet must be installed vertically in such a way that the key lock is no higher than 1.90 m from the ground (see Figure 6). Figure 6 – PWR-240 REDs cabinet max. height Please note that the cabinet door can be unlocked and opened by using the key pro- vided along with the product.
CHAPTER 4 LOW VOLTAGE ELECTRICAL CONNECTIONS DC LOW VOLTAGE CABLE INSERTION The Cable Entry Plate has several forms of sealing grommets that must be inserted to provide IP65 protection capability. This includes AS-I cable sealing grommets. Cable Entry Plate Follow these instructions to correctly insert the cables: 1.

• T2013, T2014 monitor the T20 Power Supply NOTE: The PWR-240 REDs allows the station to continue functioning even in the event of a single internal power supply failure. Therefore it is strongly recommended to connect the DC OK signals to digital alarms in order to be warned about the loss of the redundant power supply.
