1 Introduction
The product warranty becomes invalid if the following safety precautions are not followed during handling,
installation, commissioning and general use/operation of Eltek DC power supply system.
General Precautions
!
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 equipment using proper lifting techniques, do not roll, climb or drill hole in the cabinets or enclosures.
Device
Hazard
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.
Electric
Shock
Environmental Precautions
CAUTION: To avoid damage the equipment, keep objects clear of system ventilation inlets, outlets and system
fans, if any, ensuring the airflow through the units is not obstructed, and that the fans rotate freely. Use caution with
rectifiers, as they can reach extreme temperatures under load and normal operation.
Ventilated
Hot Surface
WARNING: The installer/user is responsible for ensuring that the DC 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 reliability, it is mandatory to always install SPDs in Eltek's power
Current Surge
supply systems. Follow the instructions given in "Guidelines for Lightning and Surge Protection", doc. 2024623.
Protection
WARNING: The electronics in the power supply system are designed for indoor, clean environment. When
installed in outdoor enclosures, it is important to keep the door closed during operation, and replace the filters
on a regular basis. Indoor installations in dusty or humid areas require appropriate air filtering of the room, or
Humidity & Dust
filtering of the air entering the DC power system. Follow the instructions given in "Generic Guidelines
Protection
Environmental Protection.", doc. 2038879.
Precautions during Installation
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
Qualified
performed by Eltek's personnel or by authorized and qualified persons.
Personnel
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
EMC, NEC/CEC
do not deteriorate during installation, and that it is performed in accordance with applying regulations.
Regard
Installations in USA and Canada must comply with NEC/CEC requirements.
!
CAUTION: Before you start the electrical installation, you must always disconnect all external AC supply fuses, as well as
internal battery and load fuses/ breakers, if any.
Device
Hazard
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
Electric
remove metallic objects — uninsulated tools, rings, watches, etc. — from the vicinity of the batteries.
Shock
WARNING: 60V and higher DC power systems are only to be installed in Restricted Access Locations (RAL).
Access must be limited by use of tool, i.e. lock and key.
