Power Supply Systems
The product warranty becomes invalid if the following safety precautions are not followed during handling,
installation, commissioning and general use/operation of Eltek power supply systems.

General Precautions
Environmental Precautions
Precautions during Installation
CAUTION: Even though the product incorporates protection circuitry and other safeguards, it can be damaged, perform poorly or
have a reduced lifetime if it is exposed to incorrect treatment during transport, installation or service. Always handle the equip-
ment using proper lifting techniques, do not roll, climb or drill hole in the cabinets or enclosures.
CAUTION: Read the user documentation carefully before installing and using the equipment, as installation and operation is to
be performed as described in it. Always tighten screws and bolts with the torque values recommended in the documentation. For
safety reasons, the commissioning and configuration of the equipment is only to be performed by Eltek’s personnel or by author-
ized and qualified persons.
CAUTION: This product is tested and verified according to international safety, environmental and EMC standards. Any non-Eltek
equipment installed into this product after delivery might influence the performance and could infringe the original approvals. The
installer is responsible for ensuring that the environmental properties of this product/ system do not deteriorate during installa-
tion, and that it is performed in accordance with applying regulations.
Installations in USA and Canada must comply with NEC/CEC requirements.
CAUTION: Before you start the electrical installation, you must always disconnect all external supply fuses, as well as internal
battery and load fuses/ breakers, if any.
CAUTION: To avoid damage the equipment, keep objects clear of system ventilation inlets, outlets and system fans, if any, ensur-
ing the airflow through the units is not obstructed, and that the fans rotate freely. Use caution with power modules, as they can
reach extreme temperatures under load and normal operation.
WARNING: The installer/user is responsible for ensuring that the power system is not damaged by current surges, over-voltages,
etc. caused by external transients, lightning, electrostatic discharge, etc. To avoid damage and obtain the expected system reli-
ability, it is mandatory to always install SPDs in Eltek’s power supply systems. Follow the instructions given in “Guidelines for
Lightning and Surge Protection”, doc. 2024623.
WARNING: The electronics in the power supply system are designed for indoor, clean environment. When installed in outdoor
enclosures — using heat sinks or closed loop heat management systems — it is important to maintain the equipment closed and
tight during operation, to avoid external air entering the enclosure. Also, when using open loop heat management systems, it is
important to replace the filters on a regular basis. Indoor installations in dusty or humid areas require appropriate air filtering of
the room, or filtering of the air entering the power system. Follow the instructions given in “Generic Guidelines Environmental
Protection.”, doc. 2038879
WARNING: Opening the equipment may cause terminal injury — even if the mains AC supply is disconnected. Hazardous voltages
may be present inside, as large capacitors may still be charged.
WARNING: For safety reasons (high leakage current / high touch current) you must always connect the AC earth wire (PE) to the
terminals, before you connect the AC input cable(s).
The batteries, if any, represent a major energy hazard. To avoid short-circuit of battery poles, you must always remove metallic
objects — uninsulated tools, rings, watches, etc. — from the vicinity of the batteries.
