Connections shall be made in the following order;
4.2.1.1. Protective Earth (PE) Connection
Input protective earth connection terminal
PE
of the UPS shall be connected to ground with a low
impedance connection.
PE terminals of the loads shall be connected to output protective earth terminal of the UPS.
If there is an external battery cabin present, it shall be grounded via battery protective earth terminal of the
UPS.
4.2.1.2. Input Connection
Please add four-pole (4-pole) circuit breaker (equivalent UPS input breaker) to distribution panel
where UPS
is to be connected. Do not connect any other load to this circuit breaker and please do not forget to add
leakage current relay.
Leakage protection relay value must be the total value of 300mA (UPS input leakage current relay) and total
leakage current value of the load connected to UPS. Relay must be protected type against peak current that
can be happened on EMI filter capacitor.
Connect the phase cables to
Input L1-L2-L3
terminals, the neutral to
Input
N
terminal. Neutral connection
should be done directly from distributon neutral bus to UPS neutral.
The device shall be earthed for a safe and reliable operation. Connect the PE ground
connectors before connecting any other cable.
If PE cables come along with the power cables; PE cable should be min. 10cm longer than the
other cables.
The installation and adjustment of distribution panel should be done by authorized Technical
Personnel.
Swicth
the circuit breaker on the distribution panel to “0” position before making the
connections.
According to EN 62040-1, the user should place a warning label on the input distribution
panel and the other primary power isolators, in order to prevent the risk of voltage backfeed.
This label is sent with the UPS It indicates:
RISK OF VOLTAGE BACKFEED
•
Isolate Uninterruptable Power Supply before working on this circuit.
•
Then check for Hazardous Voltage between all terminals including the protective earth
(PE).
