!WARNING

Hazardous voltages are present in certain parts of this electrical equipment during operation.Incorrect handling of the

equipment can result in death, severe personal injury or substantial property damage. Only qualified personnel are allowed

to work on or around this equipment. The successful and safe operation of this equipment is dependent on proper transport,

storage and installation.

Before installation or maintenance work is carried out, the mains switch must be switched off and locked to prevent it from

being switched on again. If these rules are not adhered to, contact with live parts or improper use can result in death or

severe personal injury.

CAUTION

The device may only be opened by qualified personnel. Electrostatically sensitive devices (ESD)

Description

The optional mains buffer module is a built-in device belonging to the SITOP series.

The device must be installed taking into account all relevant DIN/VDE specifications and other national standards.

It is used in combination with a stabilized 24 V load power supply unit (SITOP 20A (6EP1436-3BA00) or SITOP 40A (6EP1437-3BA00)) to

buffer the load current if the AC power supply is interrupted temporarily.

The buffer module is connected in parallel with the SITOP load power supply unit. The "+" input of the buffer module must be connected to

the "+" output of the power supply unit for this purpose, and the "-" input of the buffer module to the "-" output of the power supply unit (see

wiring information on page 2). The buffer module must be wired with the same conductor cross-section as the output cable of the power

supply.
