Description

The SITOP power supply is a built-in unit, degree of protection IP20, protection class I.

Primary switched-mode power supply for connection to 1-phase AC system (TN, TT system in accordance with IEC 60364-1) with rated voltages of 100 - 240 V, 50 - 60 Hz; 24 V DC output voltage, isolated, short-circuit and no-load proof.

See Figure 1 View of devices.

Safety instructions

NOTICE
Appropriate transport, proper storage, mounting, and installation, as well as careful operation and service, are essential for the error-free, safe and reliable operation of the device/system.
Setup and operation of this device/system are permitted only if the instructions and warnings of the associated technical documentation are carefully observed.
Only qualified personnel are allowed to install the device/system and commission it.

Mounting

Mounted on a standard mounting rail TH35-15/7.5 (EN 60715).

The device should be mounted so that the terminals are at the bottom.

A clearance of at least 50 mm must be maintained above and below the device (max. cable duct depth 50 mm).

See Figure 2 Design

Connecting up

Before starting any installation or maintenance work, the main system switch must be opened and measures taken to prevent it from being reclosed. If this instruction is not observed, touching live parts can result in death or serious injury.

It is only permissible to use an insulated screwdriver when actuating the potentiometer.

For installation of the devices, the relevant country specific regulations must be observed.

A miniature circuit breaker or motor circuit breaker must be provided on the input side.

The supply voltage must be connected according to IEC 60364.

Use copper wire certified for 60/75°C.

For operation at 2 line-to-line voltages, a suitable fuse protection is required at terminal N.
