In order to gain access to the following cards, remove the metal protective panel.
Only trained and authorised personnel must gain access to this area
3.3.3 REMOTE ALARMS (2 optional cards)
6 outputs: potential-free contacts for alarms (programmable from the
display panel), 2 inputs (programmable from the panel) and 1 12V DC
maximum 100mA auxiliary input.
3.3.4 MODEM (optional)
Model compatible with the communication standards between the
MASTER HE and the software provided.
N.B. the modem must be connected to an RS232 port (D and E), a standard RS232 port may not therefore be used.
3.3.5 MULTI I / O (optional)
The function of this
accessory is to convert external signals from the MASTER HE (e.g. temperature of
environment, temperature of battery premises, etc.) into signals by means of relay contacts or via serial output RS485
in MODBUS protocol.
It has the following characteristics:
- 8 inputs (e.g. humidity, smoke, etc. sensors)
- communication with the UPS via serial port
- 8 relays configurable with 8 events on the MASTER HE
- RS232 output port with configurable messages
- RS 485 output port MDBUS /JUBUS with configurable messages.
3.3.6 REMOTE PANEL (OPTIONAL)
The remote panel allows the UPS to be monitored from
a distance and the user to have a detailed overview of
the state of the machine in real time. Using this
device, it is possible to keep the electrical mains,
output and battery measurements etc, under control and
to detect any alarms.
For details relative to use and connection, refer to the
specific manual.
3.3.7 Dual Bus System
– UGS
(optional)
Two independent systems may be configured with Dual
Bus with a single source or a separate source.
The synchronization option (UGS) keeps the outputs of the two systems always synchronized, regardless of the input
variations and when the system is running from the battery. Each system may be made up of a maximum of 4
parallel-connected UPSs. This system has been designed for configurations using STSs (Static Transfer Switches)
since this guarantees switching from one uninterruptible source to another without affecting the loads.
