1. Unpacking Instructions
1. Inspect the shipping crate for any signs of damage that may have occurred while in
transit.
Figure 1: Inspect the shipping crate for signs of damage
2. Inspect the ShockWatch and TiltWatch devices, which are adhered to the outside of the
wooden packing crate. Verify that their indicators are not red.
A red indicator is a sign of rough handling (ShockWatch) or tip-over (TiltWatch).
Notify the carrier and Gamatronic Support immediately if rough handling of the
UPS is suspected or if any damage is found or suspected.
3. Retain the shipping crate and packaging materials for future use.

Figure 2: ShockWatch and TiltWatch devices
These devices indicate if the package was subject to shock or tip-over.
4. Using a forklift, move the shipping crate close to the place in which the UPS will be
installed.
5. Cut and remove any straps that are on the shipping crate.
6. Stand on a secure ladder and use an electric screwdriver to remove the screws that are
holding the roof of the shipping crate in place. Then remove the roof.

Figure 3: Remove the roof and support beam (use electric screwdriver)
7. Remove the screws that are holding the walls and support beams of the crate in place.
Then carefully remove the walls themselves leaving the UPS standing on its wooden
shipping pallet.
Figure 4: Remove the walls of the crate
8. Cut and remove any straps that are securing the UPS to the shipping pallet.
9. Remove the plastic wrapping and all other packaging material from the UPS.
Be careful to avoid scratching the finish of the Modular UPS.
10. Lift the UPS from the shipping pallet and move it to the location where it will be
installed.

2. Safety Precautions
The UPS system is designed for a wide range of environments. Nevertheless, the modular UPS
should be handled with care, according to the following guidelines.
Do’s
Read this manual and the User Guide carefully before starting installation and operation of the
UPS.
Review the safety precautions described below to avoid injury to users and damage to the
equipment.
This UPS is intended for installation in a temperature-controlled, indoor area that is free from
conductive contaminants.
All power connections must be completed by a licensed electrician who is experienced in
wiring this type of equipment, and who is familiar with the local electrical codes and
regulations. Improper wiring may cause damage to the equipment, injury to personnel, or
even death.
Ensure all power is disconnected before performing installation or maintenance.
See Table 3 and Figure 7 for recommended clearances.
The UPS must be well grounded to the building’s grounding system with a conductor that has
a current carrying capacity that matches the rating of the UPS, according to local codes.
Battery installation, battery maintenance, and battery replacement shall be performed only by
authorized service personnel.
Pay attention to all DANGER, CAUTION, and WARNING notices affixed to the inside and
outside of the UPS.
Keep the surroundings clean, uncluttered and free from excess moisture.
Keep the operating environment within the parameters stated in this document.
Allow only qualified technicians to service the UPS. There are no user-serviceable components.
Do not try to repair it yourself!
Use the UPS only for its intended purpose.
The batteries should preferably be installed next to the UPS, or as close to it as is practically
possible.

UPS for 400 Vac Grid, Installation Guide, doc. rel. 3.0
5
If you remove a power module from the UPS while the module is operating, wait five minutes
before reinserting the module. This allows the module’s capacitors time to discharge.
FAST FUSES (SEMICONDUCTOR FUSES) must be used between the battery and the UPS –for
example, the Ferraz Shawmut A70QS fuse.
WARNING - RISK OF LETHAL ELECTRIC SHOCK:
WARNING! HIGH TOUCH CURRENT!
EARTH CONNECTION ESSENTIAL BEFORE CONNECTING SUPPLY.
WARNING - RISK OF LETHAL ELECTRIC SHOCK:
The battery cabinet contains a series of batteries that provides high
voltage and energy in the UPS body even when the UPS is not
connected to the ac input.
Take appropriate precautions during installation, inspection and
servicing.
Don’ts
Do not open the cover of the UPS or the battery cabinets under any circumstances. All UPS
panels and doors should be closed.
Do not insert any objects through the ventilation holes.
Do not put objects on the UPS.
Do not move the UPS while it is operating.
Do not use the UPS outdoors.
Do not turn the UPS upside down or lying down during transportation.
Do not connect or disconnect any AC or DC cables to the battery cabinet or UPS unless ALL
the battery circuit and AC circuit breakers are turned OFF.
Do not turn ON the battery circuit breaker when the battery cabinet is disconnected from the
UPS.
Do not install the UPS next to gas or electrical heaters. A restricted location is recommended
in order to prevent access by unauthorized personnel.

UPS for 400 Vac Grid, Installation Guide, doc. rel. 3.0
If you remove a power module from the UPS while the module is operating, do not reinsert
the module immediately. Wait five minutes.
WARNING - RISK OF LETHAL ELECTRIC SHOCK:
This UPS receives power from more than one source!
Disconnection of all ac sources and dc sources is
required to de-energize this unit before servicing.
WARNING - RISK OF LETHAL ELECTRIC SHOCK:
Do not touch uninsulated battery terminals.

3. System Structure and Installation
The UPS is composed of:
Up to 10 power modules, each providing 30 kVA/30 kW
Static switch module
System controller
Maximum output capacity of the UPS is 300 kVA/300 kW.

ALL POWER CONNECTIONS MUST BE COMPLETED BY A LICENSED
ELECTRICIAN WHO IS EXPERIENCED IN WIRING THIS TYPE OF EQUIPMENT,
AND WHO IS FAMILIAR WITH THE LOCAL ELECTRICAL CODES AND
REGULATIONS.
IMPROPER WIRING MAY CAUSE INJURY TO PERSONNEL AND/OR DAMAGE
TO THE EQUIPMENT.
IN THE EVENT THAT THE UPS HAS BEEN DISCONNECTED FROM THE AC
MAINS FOR FOUR MONTHS OR LONGER FOLLOWING ITS DELIVERY TO
THE CUSTOMER SITE,THE UPS MUST BE CONNECTED TO THE AC MAINS
AND OPERATED WITH NO LOAD FOR A PERIOD OF FOUR HOURS,BEFORE
APPLYING A LOAD.

3.1. Important Installation Information
The Gamatronic UPS must be connected a “4-wire + Ground” configuration (i.e., 3 phases +
Neutral + Ground). The voltage displayed on the status screen is the Phase-to-Neutral voltage.
The Neutral line MUST be connected to the UPS on the input and output stages of the UPS. The
UPS will support phase-to-phase loads and phase-to-Neutral loads. The Neutral line must always
remain connected when the UPS is operating. All input, output and dc cables must be armored,
and the armored layer must be connected to the UPS ground connection terminals only.
