Use of Differential Protection Devices

Notice - Differential Current Breakers

•

The UPS does not require differential protection devices connected ahead of it.

However,  when  these  devices  are  installed  in  compliance  with  local  regulations,  note  that
separate  DCBs  in  the  line  power  and  bypass  line  power  circuits  may  trip  unexpectedly,  thus
interrupting the power supply to the unit.
Therefore,  if  a  DCB  must  be  installed,  only  one  should  be  used  for  both  primary  and  bypass
inputs.

•

In parallel distributed systems, only one common differential protection device should be

installed ahead of the point where the line divides into the UPS primary and bypass line power
circuits. If separate DCBs are installed in different configurations, they may trip unexpectedly.

•

In order to guarantee correct distribution in the neutral cables, installation personnel shall make

sure that the lengths of the cables are as equal as possible.
However,  if  the  bypass  lines  lead  from  sources  that  are  electrically  isolated  from  each  other,  a
differential  protection  device  may  be  installed  on  each  line.  In  this  case,  and  in  cases  when  the
load is supplied from the bypass via the Static Bypass Switch, the isolated sources are connected
in  parallel.  A  case-by-case  analysis  should  be  made  as  to  whether  any  resulting  imbalance
between the currents on the bypass lines is compatible with the respective protection devices.

A differential device installed on the primary and bypass inputs supply senses the sum of all ground
leakage currents in both the UPS and the load it supplies.
To avoid spurious operation, the following must be taken into consideration when selecting differential
protection devices for installation on input lines:
1.

The nominal value of ID must take into account the ground leakage current of the UPS and the load

under normal operating conditions: ID = IDUPS + load leakage current.
NB The maximum limit for UPS ground leakage current is 5% of nominal input current (see
IEC/EN62040-1+A1:2013).
2.

The differential breaker must be a delayed intervention type device (greater than 300 mS).

3.

The protection device must be differential.

2.2

Parallel Connections

The cable identified by the color green is the adapter cable that connects the MSS to the parallel cable.
The cables identified with the color red are the cables parallel.
The adapter cables (green color) are always supplied with the MSS.
Follow the table that shows the standard lengths available. The cables are optional and must be
ordered separately using the following P/N:
