ONNECTING THE REMOTE MAINTENANCE BYPASS
It is possible to install an additional maintenance bypass on a peripheral electrical panel, for example to allow the CPS to
be replaced without interrupting the power supply to the load.
It is essential to connect the "SERVICE BYPASS" terminal (see "Communication area, ext connection
area view") to the auxiliary contact of the SERVICE BYPASS switch. Closing the SERVICE BYPASS
switch (3) opens this auxiliary contact which informs the CPS that the maintenance bypass has been
connected. The absence of this connection can cause an interruption to load feeding and damage the
CPS.
•
use a cable with a 1 mm² section and double insulation for connection of the "SERVICE BYPASS" and
"SEZ_OUT" terminals to the auxiliary contacts of the remote maintenance bypass and remote output
switch isolating switches.
•
Check the compatibility between the "remote maintenance bypass" and the system neutral point treatment.
In the case of several machines in parallel, it is possible to use the switch out aux contact (J3) in order to
perform the hot swap of the CPS.

Connections inside the CPS
INPUT switch: isolating switch compliant with what is shown in the "Protection devices inside the CPS" section
OUTPUT switch: isolating switch compliant with what is shown in the "Protection devices inside the CPS"
section with auxiliary normally closed (leading) contact
SERVICE BYPASS switch: isolating switch compliant with what is shown in the "Protection devices inside the
CPS" section with auxiliary normally closed (leading) contact
N.B. If the CPS is to be used with the "separate" bypass input, connect the INPUT switch output (1) to this line directly.
