Connection
3.4.1.
Earth protection
As a device with class l protection against electric shocks, it is essential to install a protective
earth wire (connect earth
). Connect the protection earth wire to the terminal (
X5
) before
connecting the grid to the DCPS input.
On the other hand, connect the protection earth wire to the terminal (
X10
) before connecting
the load to the DCPS output.
3.4.2.
Input connection, terminals (X1 to X5)
Connect the grid cables R, S, T and N to the terminals (
X1
), (
X2
), (
X3
) and (
X4
) respectively. This
connection must always be done according to the label placed under the input screw
terminals.
In case of discrepancies between labelling and this manual instructions,
the label information
will always prevail
.
3.4.3.
Output connection, terminals (X6 to X10)
The equipment has 3 output channels (U, V and W) and a common negative return (N).
Therefore, the load must be connected between the channels and the common negative
return (phase-N):
-
DC phase output terminal U (
X8
)
-
DC phase output terminal V (
X7
)
-
DC phase output terminal W (
X6
)
-
DC negative terminal N (
X9
)
In case of discrepancies between labelling and this manual instructions,
the label information
will always prevail
.
3.4.4.
Emergency Power Off terminals (X12)
The equipment owns two terminals dedicated to external Emergency Power Off (EPO).
The EPO must act as a normally closed contact, and thus, there are two possible options for
connection:
a)
Connecting an external Emergency pushbutton to
X12
b)
Installing a cable bridge to close the circuit in terminal
X12
(in case EPO is not desired)
If option a) is chosen, the procedure is as follows:
1.
Emergency shutdown activation:
the Emergency pushbutton must be set in the
position in which it forces to open the circuit between the two terminals of
X12
.
2.
Normal mode restoration:
the Emergency pushbutton position must be inverted in
order to close the circuit again between the two terminals of
X12
.
