•
Beyond the communication bus, it is necessary to provide
the installation with parallel systems, a board provided with
the individual input and output protections and a manual
bypass with mechanical locking. See or , depending on
whether or not there is an independent static bypass line.
For more information see the documentation for the "Rec-
ommended installation".
5.5.7. Interface and communications.
•
The communications line (COM) constitutes a very
low voltage safety circuit and must be installed
separately from other lines carrying dangerous voltages
(power distribution line).
5.5.7.1. Digital inputs, dry contacts and communications.
The ADAPT2 UPS series incorporates the following connec-
tions as standard for communication with external peripherals
or with other identical equipment:
•
Four digital inputs through terminal block.
•
Four relay interface outputs via terminal block.
•
Communication via RS232/RS485 ports (subD9) or USB.
•
Two slots for installing an SNMP card or relay expansion
board (IS).
All connectors related with communications are grouped to-
gether on the interface panel and can be accessed from the
Bypass module after removing the cover, which covers them
completely.
The communication interface has the following connections via
terminal block:
•
Temperature sensors input.
ˆ
TBAT: Sensor for the compensation of the floating
voltage of batteries. Parameter shown on the control
panel display.
ˆ
TAMB: Sensor for measuring ambient temperature. Pa-
rameter shown on the control panel display.
•
Signal input for the external EPO button.
•
4 programmable digital inputs (see ).
•
4 programmable relay outputs (see ).
