SAFETY INSTRUCTIONS
SPECIAL SYMBOLS
RISK OF ELECTRIC SHOCK - Observe the warning associated with the risk of electric shock symbol.
Important instructions that must always be followed.
EU separate collection and lead content mark for lead acid batteries. Indicates that the battery must not be
disposed of to the ‘normal’ household waste but be separately collected and recycled.
EU separate collection mark for waste electrical and electronic equipment (WEEE). Indicates that the item
must not be disposed of to the ‘normal’ household waste but be separately collected and recycled.
Information, advice, help.
Refer to the user manual.
KEEP THESE INSTRUCTIONS IN A SAFE PLACE
This manual contains important instructions that should be followed during installation and maintenance of the
UPS and batteries.
All UPS models are considered operating at an optimal temperature of 20 – 25°C

C750 & C750R User
Manual Page 7
SAFETY OF PERSONS
l RISK OF VOLTAGE BACKFEED. The system has its own power source (the battery). Isolate the UPS and check for
hazardous voltage upstream and downstream during lockout-tagout operation. Terminal blocks may be
energized even if the system is disconnected from the AC power source.
l Dangerous voltage levels are present within the system. It should be opened exclusively by qualified service
personnel.
l The system must be properly grounded.
l The battery supplied with the system contains small amounts of toxic materials. To avoid accidents, the directives
listed below must be observed:
! Servicing of batteries should be performed by personnel knowledgeable about batteries and the required
precautions.
! When replacing batteries, replace with the same type and number of batteries or battery packs.
! Do not dispose of batteries in fire. The batteries may explode.
! Batteries constitute a danger (electrical shock, burns). The short-circuit current may be very high.
l Precautions must be taken for all handling:
! Wear rubber gloves and boots.
! Do not lay tools or metal parts on top of batteries.
! Disconnect charging source prior to connecting or disconnecting battery terminals.
! Determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock can
be reduced if such grounds are removed during installation and maintenance (applicable to equipment
and remote battery supplies not having a grounded supply circuit).
PRODUCT SAFETY
l The UPS connection instructions and operation described in the manual must be followed in the indicated order.
l UPS enclosure IP rating IP20.
l CAUTION - To reduce the risk of fire, the unit connects only to a circuit provided with branch circuit overcurrent
protection for
l The upstream circuit breaker for Normal AC/Bypass AC must be easily accessible. The unit can then be
disconnected from AC power source by opening this circuit breaker.
l An additional AC contactor is used for back feed protection and must comply with IEC/EN 62040-1
l Disconnection and overcurrent protection devices shall be provided by others for permanently connected AC
input (Normal AC/Bypass AC) and AC output circuits.
l Check that the indications on the rating plate correspond to your AC powered system and to the actual electrical
consumption of all the equipment to be connected to the system.
l For pluggable equipment, the socket-outlet shall be installed near the equipment and shall be easily accessible.
l Never install the system near liquids or in an excessively damp environment.
l Never let a foreign body penetrate inside the system.
l Never block the ventilation grates of the system.
l Never expose the system to direct sunlight or source of heat.
l If the system must be stored prior to installation, storage must be in a dry place.
l The admissible storage temperature range is -25°C to +55°C without battery (-15°C to +40°C with battery).
l TN-S/IT/TN-C/TT of electrical supply system may be connected by UPS.
l This UPS may be provided with a maximum of 6 extension battery cabinets or equivalent.

C750 & C750R User
Manual Page 8
SPECIAL PRECAUTIONS
l The UPS and EBMs are heavy: wear safety shoes and use vacuum lifter preferentially for handling operations.
l All handling operations will require at least two people (unpacking, lifting, installation in rack system).
l Before and after the installation, if the UPS remains de-energized for a long period, the UPS must be energized for
a period of 24 hours, at least once every 6 months (for a normal storage temperature less than 25°C). This charges
the battery, thus avoiding possible irreversible damage.
l During the replacement of a Battery Module, it is imperative to use the same type and number of batteries as the
original Battery Module provided with the UPS to maintain an identical level of performance and safety.
l This is a category C3 UPS product. In a residential environment, this product may cause radio interference, in
which case the user may be required to take additional measures.

EBM model
EBM modular installation steps are same as UPS above, Pay attention to this installation:
Tower Installation
UPS model
Screw the tower feet to the UPS: The LCD of this UPS modular has gravity sensing, the vision window will automatically
adjust the display orientation.
EBM model
1. Place EBM modular to UPS’s right side and align with front-panel.
2. Screw the UPS’s tower foot: one is to UPS’s side, another one to EBM’s side (as above)
2 EBMs are required for R 20kVA UPS, please keep an enough space for installation.
1. EBM modular must be installed on the lower level of the UPS (as shown below).
2. 2 EBMs are required for R 20kVA UPS, each EBM with a height of 3U;
therefore, 6U installation space is required for 1complete EBM.
