GENERAL NOTES
4.1.1.
INSPECTION
After unpacking the product, please inspect any damage that may have occurred during the
shipment. Save all packing materials in case the product has to be returned one day. If any
damage is found, please file a claim with the carrier immediately. Do not return the product to the
factory without obtaining the prior Return Merchandise Authorization (RMA) acceptance from
ELETTROTEST SPA.
4.1.2.
Line Connection
The HPS/T galvanic insulation from the electrical line allows to consider the HPS/T like a
transformer so the HPS/T must be protected with a differential and Magneto-thermic protection
both in input and output.
For the installer is required to strictly respect of the current regulations for this particular
installation.
4.2.
PROTECTIONS
Mandatory
Safety protection (Magneto-thermal and differential) are mandatory according to
the nominal HPS/T characteristic.
An additional adequate protection
must be add
when electrical components
(cable, Equipment under test
–
EUT) cannot support HPS/T performance.
4.2.1.
RCD Protection
It is necessary to insert a differential protection both in input and output; this because there is a
galvanic isolation from the input to the output, so the input RCD switch does not see leakage
current to the ground on the output.
Suggested RCD protections:
1.
Input line
→
1/3-Phase B-type RCD switch 30mA;
2.
1-phase Output line
→
1-phase RCD switch depend of use;
3.
3-phase Outuput line
→
3-phase RCD switch depend of use;
