Installation
DLM-E 3kW & 4kW Series Power Supplies
rated at 40V and over. Filter capacitors store potentially dangerous energy for some time after
power is removed.
Use extreme caution when biasing the output relative to the chassis due to potentially high
voltage levels at the output terminals. The output of the DLM–E Series supplies may be biased
up to a maximum voltage relative to the chassis as specified in Section 1 under
Additional
Specifications
.
2.2.2
AC Source Grounding
Ensure the power supply is connected to an appropriately rated AC outlet with the
recommended AC input wiring as set out in
There is a
potential shock hazard if the power supply chassis and cover are not connected to a power
return via the safety ground on the chassis. The third wire in a single phase AC input connector
and the fourth wire in a three phase AC input connector must be connected to an electrical
ground at the power outlet. Any disconnection of this ground will cause a potential shock hazard
to operating personnel.
This power supply is equipped with an AC line filter to reduce electromagnetic interference and
must be connected to a properly grounded receptacle, or a shock hazard will exist.
2.2.3
EMI Provisions
A clamp–on EMI suppression filter core is included with each unit to allow compliance with the
Electromagnetic Compatibility Directive requirement of the European Community. This filter is to
be installed so that all of the AC input wires and ground wire that connect to the unit at the AC
input fuse block and chassis are clamped inside the filter before operating. See Figure 2–1.
Figure 2–1. EMI Suppression Filter
2.2.4
Operating and Servicing Precautions
Exceeding a model's maximum rated input voltage may cause permanent damage to the unit.
The power supply must not be operated where flammable gases or fumes exist.
