EMOTE MAINTENANCE BYPASS
Attention
: carefully read the “Manual bypass (SWMB)” paragraph
A maintenance bypass (manual bypass) can be installed additionally on a peripheral electrical board (see following diagram).
This allows, for example, UPS replacement without interrupting power to the load.
The "SERVICE BYPASS" (see "UPS connections view") terminal absolutely must be connected to the
auxiliary contact of the REMOTE MAINTENANCE BYPASS SWITCH (3). When this switch closes, an auxiliary
contact signalling insertion of the remote bypass to the UPS must open. Failure to perform this connection
can cause power cut-off to the load and UPS damage.
•
Use switches and power cables suitable for UPS currents.
•
Use a double insulation cable with a 1mm2 section for connecting "SERVICE BYPASS" and "AUX SWOUT"
terminals to relative REMOTE MAINTENANCE BYPASS (3) and OUTPUT (2) switch auxiliary contacts.
•
Verify compatibility between the "Remote maintenance bypass" and neutral connectivity of the system.
