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 3-phase AC system (TN, TT system in accordance with IEC 60364-1) with rated voltages of 400 – 500 V, 50 – 60 Hz; 24 V DC output voltage, isolated, short-circuit and no-load proof.
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 (EN 60715).
- The device should be mounted so that the terminals are at the bottom.
- A clearance of at least 40 mm must be maintained above and below the device (max. cable duct depth 50 mm).
Connecting up
WARNING
Before starting any installation or maintenance work, the main system switch must be opened and measures are 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.
When installing the devices, the relevant country-specific regulations must be observed.
Important note:
A fuse, a miniature circuit breaker, or a circuit breaker must be provided at the input. The supply voltage must be connected according to IEC 60364 and EN 50178.
Use copper cable certified for use at 90 °C.
