3. Read Before Proceeding
The EL 400 DRO is sophisticated electronic equipment and should be
carefully handled to avoid any damage.
The rated supply to DRO should be within specified limits and should
not be exceeded under any circumstances. Doing so may cause
irreversible damage to DRO.
DRO should be opened by authorized person only. Otherwise it will
invalidate the warranty of the unit.
Equipotential Point (Ground) should be provided to avoid erratic
operations of DRO.
Cable routing of DRO and encoders should not be routed through or
nearby high capacity switching/inductive load or where it can cause
danger.
EL 400 DRO is standard compliant with
EMC Directive EN61326 Standard 61326-4-2, 61326-4-4,
61326-4-11, 61326-4-5, CISPR 16-1 and 16-2.
RoHS compliant.
Warranty will be considered void if and not limited to
Failing to meet manufacturers specified supply conditions.
Abusive handling.
Environmental conditions outside of Manufacturers
specifications.
Manipulation, tampering of electronics.
Replacement of original parts with other parts than
specified by manufacturer.
Disposal
At the end of its life the EL 400 DRO system should be
disposed of in a safe an environmentally sympathetic manner
as applicable to local legislation. The casework and other
components may be suitable for recycling. DO NOT BURN.

5.2. Power Supply
The EL 400 DRO series uses a Switch mode power supply inside
which covers the universal power input range i.e. 90VAC to
265VAC / 50 to 60 Hz. Ensure the input power is within the
specifications before powering the unit.
The power supply to the DRO should not be given from the same
source as that of any high capacity switching / inductive loads to
avoid interference.
Ensure proper equipotential point (Ground) connection is provided
to the DRO to avoid any erratic operations.
5.3. Encoder Connections
Encoder Cable should be properly routed as per manufacturers’
guidelines. Cable should not be routed near any inductive loads to
avoid electrical noise interference. It should be routed away from
the machine moving parts to avoid any damage.
