INSTALLATION
Check the Safety Instructions.
Make sure that the data on the characteristics plate are those required for the installation.
Any incorrect connection or handling may cause damage to the UPS and/or the loads connected to it. Read
these instructions carefully and follow the steps in the order indicated.
Reference is made in this manual to terminal connections, the use of switches or devices with extended back-
up times that are only available in the M4T-B version. Omit all references to these if your device does not have
them.
This UPS must be installed by qualified staff but can be used by personal with without any specific preparation
aside from this “User Guide”.
4.1
Important Safety Instructions.
As this is a device with class I protection against electric shocks, it is essential to install a protective earth
conductor (earth connection
(
)).
Connect the conductor to the terminal (X5), before connecting the power
supply to the UPS input.
All connections to the device, including those for control (interface, remote control, etc.), will be performed with
the switches in the off position and without any mains present (UPS power line cut off “Off”).
It should always be remembered that the UPS is a generator of electrical power, so users must take all
necessary precautions against direct or indirect contact.
Warning labels should be placed on all primary power switches installed in places that are not in the vicinity of
the device to alert the electrical maintenance personnel of the presence of a UPS in the circuit.
The label will bear the following or an equivalent text:
Before working on this circuit.
- Isolate the Uninterruptible Power Supply (UPS).
-Then check for Hazardous Voltage between all terminals including the protective earth.
Risk of Voltage Back feed
When the power supply reaches the UPS input with static bypass included or with an independent static bypass
line, although the inverter is “Off” (shut-down), it does not mean there is no output voltage at the output
terminals.
To do this, (Q1a), (Q4) and (Q2) must be switched to the “Off” position.
The UPS may be supplying output voltage from the manual bypass which must be taken into account for safety
purposes. If the output power supply of the UPS has to be interrupted in this situation, deactivate the switch
(Q5).
Precautions must be taken for devices with battery terminals, as they are not isolated from the alternating input
line, and there could be dangerous voltage between the battery terminals and the ground.
4.1.1
Batteries.
Batteries should be handled and connected or supervised by personnel with battery knowledge.
For units requested without batteries, the batteries will always acquired, installed and connected by the
customer and under his responsibility. The battery details (number, capacity and voltage) are indicated on the
battery label pasted beside the nameplate of the equipment. These requirements should be strictly adhered to
as well as the battery polarity connection and the circuit diagram provided with this documentation.
The battery supply may involve the risk of electric shock and may produce high short circuit current. Please
observe the following preventive measures before manipulating any terminal block identified on the label as
“Battery”:
