1 GENERAL INFORMATION AND FEATURES The compact iDRN power supplies are designed to supply well-regulated 24 volt DC power to sensors, signal conditioners, data acquisition systems and high level logic equipment.
SAFETY CONSIDERATIONS 2 This device is marked with the international Caution symbol. It is important to read this manual before installing or commissioning this device as it contains important information relating to Safety and EMC (Electromagnetic Compatibility). Unpacking & Inspection Unpack the instrument and inspect for obvious shipping damage. Do not attempt to operate the unit if damage is found. This instrument is a DIN rail mount device.
3 INSTALLATION AND REMOVAL Warning! If a rail assembly is to be transported, then disconnection, dismounting and separate packing of the power supply is recommended. For units that must be shipped installed on the rail, additional bracing to resist transportation shocks is recommended. Do not attempt to install or connect to the power supply when the mains are energized.
INSTALLATION AND REMOVAL 3 3.1 Installation Clearance Ensure that there is enough room for mounting the power supply unit. There should be a minimum of 1" [25mm] spacing to allow sufficient air circulation for proper cooling. 1" [25mm] 1" [25mm] AC POWER IN SIGNAL INPUT SIGNAL INPUT DC POWER IN DC POWER IN SIGNAL INPUT DIN RAIL SIGNAL CONDITIONER MODULES DC POWER OUT DC POWER IN POWER SUPPLY 24V-BUS Figure 3.
3 INSTALLATION AND REMOVAL 3.2 Mounting on DIN Rail To install unit onto DIN Rail 1. Tilt unit, position mounting slot onto DIN Rail, as shown. 2. Push unit towards DIN Rail and it will snap into place. Figure 3.
INSTALLATION AND REMOVAL 3 3.3 Removal of Unit 1. Insert flat screw-driver into tab and push downwards. 2. Unit will detach from DIN Rail. Figure 3.
4 INPUT AND OUTPUT CONNECTIONS 4.1 Block Diagram of Power Supply Figure 4.1 — Block Diagram 4.2 Wiring Warning: Do not turn on the ac power to the power supply unit until you have completed all output connections. Failure to do so may result in injury! This device must only be installed electrically by a specially trained electrician with corresponding qualifications.
