5.2.4 Emergency Power Off (Remote E.P.O.)
In accordance with the standards, the UPS is fitted with an emergency device that uses a normally closed contact (already
installed on the UPS) that can be opened to activate the emergency machine power off.
The E.P.O. terminals are in the UPS’s rear panel on pins 3 and 4 of the 6-pole Combicon connector installed on contact
interface.
To connect the emergency power off device please follow these instructions:
- Use a cable with double insulation, no more than 10 metres in length.
- Check that the switch used is galvanically insulated.
Electrical specifications of the E.P.O. interface:
- Voltage between terminals 3 and 4 (6P Combicon) with open circuit = 12Vdc.
- Current between terminals 3 and 4 (6P Combicon) with closed circuit = 5mA
The following figure shows how the emergency power off device has to be connected.
5.2.5 Installing the Trimod® BATTERY
It is possible to connect external battery units to increase ups autonomy.
If the configuration uses more than one battery it is necessary to position all the Trimod® Battery units on the same side
of the UPS Trimod® and connect them in cascade with each other using the multicore cables supplied.
There are four different external battery cabinets for the Trimod® BATTERY units:
- a modular model consisting of a cabinet with an internal structure that uses battery drawers for up to a maximum of 80
12V 7.2Ah or 12V 9Ah batteries (16 drawers).
- a modular model consisting of a cabinet with an internal structure that uses battery boxes for up to a maximum of 100
12V 7.2Ah or 12V 9Ah batteries (20 drawers).
- a compact, non modular, economical model that uses a shelf architecture instead and on which the batteries are
placed. It can house 60 or 120 12V 7.2Ah or 12V 9Ah batteries.
- a compact, non modular, economical model that uses a shelf architecture instead and on which the batteries are
placed. It can house 20 12V 94Ah batteries.
A Trimod® BATTERY can be connected to several UPS Trimod® units.
WARNING
The following instructions are of a prescriptive nature and it is imperative they be complied with.
Opening or removing the panels from the UPS Trimod® or Trimod® BATTERY you risk exposure to high and dangerous
voltages! To guarantee protection of personnel during installation of the Trimod® BATTERY make sure that the connections
are done under the following conditions:
1. There must be no mains voltage
2. The loads are off and disconnected;
3. The UPS Trimod® is off with no voltage and all fuse carrier isolating switches on the UPS Trimod® and Trimod® BATTERY
are open.
