DC 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
DC power supply system.
SAFETY and ENVIRONMENTAL PRECAUTIONS
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 confi guration of the equipment is only to be performed by
Eltek
’s personnel or by author-
ized and qualifi ed persons.
CAUTION:
The installer is responsible for ensuring that the EMC properties of this product/ system do not deteriorate during in-
stallation, 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 AC 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 airfl ow through the units is not obstructed, and that the fans rotate freely. Use caution with rectifi ers, as they can reach
extreme temperatures
under load and normal operation.
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 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 en-
closures, it is important to keep the door closed during operation, and replace the fi lters on a regular basis. Indoor installations
in dusty or humid areas require appropriate air fi ltering of the room, or fi ltering of the air entering the DC 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.
WARNING: 60V 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.
