5.2.3.1 Inview S Slot - Connections
Inview S Slot has an ETH port and USB at the front. Output relays, free potential contacts, Modbus and power connections
are present at the rear side of the Inview S Slot connected shelf.
Inview S Slot - Front connections
•
LAN port is used for network connectivity and user can access the system
information in the Web Interface.
• USB
port is used to access the Inview S configuration and setup files.
Inview S Slot - Shelf rear connections
• Digital Inputs (D1 and D2):
Two potential free Digital Inputs are available for customer connections.
ƒ
Digital Input 1 is assigned for MBP operation if used.
ƒ Digital Input 2 is assigned for Surge Arrester if used.
•
Output Relays (K1 and K2): Two output relays are available and can be used for Major and Minor Alarms.
• CAN Modbus (RS485)
port is used to establish communication between Inview S Slot and MBB. It also provide
the +12 Vdc power to one connected MBB.
•
Power: The addi12 V for Inview S Slot and it is from external Auxiliary power supply converter. This
power should not be shared with other devices. By default, Inview S Slot works on output DC from modules. If

5.3 Manual By-Pass
The manual by pass operates via manually operated switches to create a short circuit from the
AC main input directly to the output AC distribution. Standard manual by-pass is “Make before
Break”. When engaged or disengaged, no disturbance is transmitted to the load.
When MBP is engaged, inverter modules are switched off and can be removed without impacting
the load. The battery supply is not physically disconnected. After disconnecting the battery
supply (by opening the battery breakers), the shelf section is safe for maintenance.
Warning: When the system is in by-pass, the load is subjected to AC main disturbances. Before engaging manual
bypass, make sure the voltage difference between AC IN and AC OUT should be less than 5 Vac to limit the inrush
current.
