- OR -
Figure 3: ShockWatch and TiltWatch devices
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).
NOTE!
These devices indicate if the package was subject to shock or tip-over.
NOTE!
If rough handling of the UPS is suspected or if any damage is found or
suspected, do not unpack the system and notify the carrier and SolarEdge
Support immediately.
3. Retain the shipping crate and packaging materials for future use.
4. Using a forklift, move the shipping crate no less than 5 meters / 16.5 feet from the place
in which the UPS will be installed with the back of the crate facing the installation site.

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 5: Remove the crate roof and support beam (use electric screwdriver)
7. Remove the screws that hold the walls and support beams of the crate in place.
8. Carefully remove the walls, pallet stoppers, ramp securing pins and seismic brackets
leaving the UPS free standing on its wooden shipping pallet. Keeps the ramp securing
pins and the seismic brackets including their screws for final assembly.

3. 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.
3.1. Do’s
Read this manual 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.
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.
Neutral must be firmly connected throughout operation of this unit.
Battery installation, battery maintenance, and battery replacement shall be performed
only 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.
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.
External batteries should preferably be installed adjacent to the UPS.
Power module removal or replacement shall be performed by a certified service
technician. If the service technician removes a power module from the UPS while the
module is operating, the service technician must 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.
To safely service the UPS open all AC and DC (input, output, and battery) circuit breakers,
and open all protective battery fuses (for positive and negative poles, as well as for mid-
points). Verify 0v across all UPS terminals relative to ground.

WARNING - RISK OF LETHAL ELECTRIC SHOCK:
WARNING! HIGH TOUCH CURRENT!
EARTH CONNECTION ESSENTIAL BEFORE CONNECTING POWER SUPPLY
WARNING - RISK OF LETHAL ELECTRIC SHOCK:
This UPS is intended to be used with a neutral. The neutral line must be
connected at all times.
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.
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.

11
UPS for 208 Vac Grid, B60US-IB Installation Guide, doc. rel. 3.3
3.2. 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 rest objects on the UPS or battery cabinet.
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 UPS or battery cabinet unless
ALL the AC circuit and battery circuit breakers are turned OFF. Verify 0v across all UPS
terminals relative to ground.
Do not turn ON any external battery circuit breaker when the battery cabinet is
disconnected from the UPS.
Do not install the UPS next to gas or electrical heaters or under an air conditioner. A
restricted location is recommended to prevent access by unauthorized personnel.
A restricted location is recommended to prevent access by unauthorized personnel.
If you remove a power module from the UPS while the module is operating, do not
reinsert the module immediately. Wait five minutes.
