Page 5: Terminology And Abbreviations
Terminology and Terminology Descriptions Abbreviations Describes a condition where the supply voltage is in the rated supply voltage range and the Power supply mode supplying power supply can deliver enough current for the buffer module and the load. This mode can also be called “Normal mode”. Describes a condition where the input voltage is below the transfer threshold level, the unit Buffer mode is running on capacitors (buffering), and the output is loaded within the allowed limits. -

Page 9: Select The Backup Threshold Voltage
Select the Backup The functionality of the buffer is determined by what mode the buffer is in, either Fixed mode or Variable mode. You can set the mode using the backup Threshold Voltage jumper selector. The factory default setting is Fixed mode. If the buffer has no jumper, it is also in Fixed mode. -
Page 10: Buffer Time
Buffer Time The buffer time (sometimes also called autonomy time) is the maximum period for which the capacitor can maintain the required output current. The buffer time mainly depends on the output current in buffer mode. To increase the buffer time, any given number of buffer modules can be connected in parallel. -

Page 19: Mounting Brackets
Mounting Brackets This section describes the brackets that can be used to mount the buffer module. Wall Mounting Bracket 1606-XLC This bracket is used to mount the buffer module on a wall without using a DIN rail. To mount a unit on a wall or a panel, the two Zinc-plated steel brackets have to be installed on the side of the unit. -
Page 20: Side Mounting Bracket 1606-Xla-S76
Side Mounting Bracket 1606-XLA-S76 This bracket is used to mount the buffer module sideways with or without using a DIN rail. The two aluminum brackets and the black plastic slider of the unit have to be detached, so that the steel brackets can be mounted. For sideway DIN rail mounting, the removed aluminum brackets and the black plastic slider must be mounted on the steel bracket. -
