100 Receiving your Herytage UPS
Caution: The Herytage UPS assemblies are very heavy, insure you are prepared
to unload, unpack, and move these weights.
101 Unpacking and Inspection
Upon receiving shipment of your equipment, it is important to check items received
against the packing slip. Check all pieces for shipping damage by unpacking and
inspecting. If items are missing or damaged, call our customer service department.
They can assist in filing a claim with the shipping carrier.
If installation requirements are not immediate, it is best to repack the system into its
original packing material for storage.
102 Storage
Store Herytage UPS prior to use at temperatures between –20º and +40º Celsius (-4º
to +104º Fahrenheit). Protect the system from moisture and weather.
If storing the Herytage UPS modules containing batteries, it is best to store them at
temperatures less than 77º Fahrenheit. This allows the batteries to have a longer shelf
life. If you plan to store them for more than 4 months it is important to unpack the
system to recharge the batteries. Consult with the factory customer service
department for assistance.

BILS-10003 rev E 8
200 Installation Guidelines
Herytage UPS are intended to be installed in a temperature controlled, indoor area
free of conductive contaminants.
See specifications for more details on the temperature range, environment, and
altitude. In addition consider any national and local codes you may have to follow.
201 Installation considerations
Before installation of your new Herytage UPS, be sure to take into consideration the
site you have selected. UPS systems produce heat and therefore require ventilation
as well as accessibility.
Consider these factors:
- Input Source Voltage - Ventilation
- Available Single Phase KVA - Size of the UPS
- Bypass Switch - Weight of UPS and Batteries
- Excessively Long Power Runs - Room Temperature
- Distance to Critical Load - Audible noise
- Proper Ground Techniques - Clearances
- Generator Applications - Accessibility
- Remote Emergency Power Off - Communications
202 Location
When you plan the location of your UPS, remember to:
•Avoid temperature and humidity extremes
•Provide shelter from the elements (especially moisture)
•Place as near as possible to the computer or other critical loads
•Maintain 8 inches of clearance in back for ventilation, and a minimum of 36 inches
in front for ventilation and maintenance. A larger clearance in front is helpful, but
not required.

BILS-10003 rev E 9
203 Remote battery installations
If the batteries are installed in a remote location (battery room) utilize DC circuit
protection rated at 250A and 20,000A AIC rating. If the batteries must be some
distance from the UPS you may need to install larger battery cables between the
battery cabinets and the UPS. Call your customer service representative if you would
intend to use anything other than standard cable lengths.

300 Wiring Instructions
There are two basic installation configurations of the Herytage UPS system. Following
is an overview of each configuration.
- Soft-wired (Line cord & receptacles)
- Hard-wired with external bypass switch
Installation of electrical wiring should be completed by a qualified electrician.
National electrical code and applicable local codes should be followed.
301 Soft-wired installation (Line-cord and receptacle)
Installation requires a proper wall receptacle for the Herytage UPS power cord to plug
into, and installation of external bypass receptacles.
Note: External bypass receptacles provide power to your load equipment in the event
that the Herytage UPS requires maintenance.
Proper breaker sizing for the input line cord receptacle depends on the input voltage /
plug option ordered, see Table 301-1. Review the Herytage UPS input voltage on the

BILS-10003 rev E 12
name plate – if it differs from the power you have available in your building call Legacy
Power Conversion customer service.

302 Hard-wired Installations
General requirements for hardwire Herytage UPS installations
– Input over-current protection and Output over-current protection and AC output
disconnect switch for Herytage UPS must be provided by the installer. It should be
installed and sized according to national and local electrical codes.
– External bypass switches should be installed within sight of Herytage UPS.
– Follow applicable national and local electrical codes when installing the grounding
system. Herytage UPS grounding conductor should be at minimum the same size
(ampacity) as circuit conductors.
– All circuit conductors including the neutral should be the same size (ampacity).
– Use isolated ground receptacles to obtain the best protection against electrical
noise.
– A separate dedicated conduit system should be utilized for the Herytage UPS input
and output wiring.
– Flexible conduit should be used to allow movement of the Herytage UPS to gain
side service clearance.
– Load imbalance should not exceed 40% / 60%; 2-4K units do not have this
restriction. 6K units L1-N 100% max., L2-N 50% max.
302-1 External bypass switch installations
The 2kVA through 20kVA Herytage UPS may be ordered with an external bypass
switch. The external bypass switch is typically mounted on a wall within site of the
Herytage UPS. See Figure 302-1A.
1. The wiring access panel for the external bypass switch is located on the front
bottom half of the external bypass switch module, remove the screws securing
the bottom half of the front cover to obtain access to the terminal blocks. See
Figure 302-1B
2. Input and output wiring to and from the Herytage UPS and to and from the
external bypass switch should be routed through separate conduits. Conduit
connection points are located on the back of the UPS, the same conduit
connection points are on the external bypass switch. Locate the pre-punched
knockouts for starter holes.
3. Review input and output voltages on the unit data plate and insure they are
proper for your installation, select wiring connection diagram figure 1 or 2 for
appropriate connection. If the wrong input or output voltages were ordered –
call Legacy Power Conversion customer service for assistance.

303 Battery installation and connection
Herytage UPS systems have internal batteries that are already connected or external
batteries that must be installed and connected before operation of UPS. To install and
connect the batteries in the external cabinet, refer to the Battery Wiring Diagram
supplied with the battery cabinet.
The following precautions should be observed when working on batteries:
- Remove watches rings and other metal objects.
- Use tools with insulated handles.
- Wear rubber gloves and boots.
- Do not lay tools or metal parts on top of batteries.
Determine if the battery is inadvertently grounded. If so remove the source of ground.
Contact with any part of the grounded battery could result in electrical shock.
Note: Refer to enclosed battery connection diagram for battery connection
instructions for UPS utilizing extended runtime batteries (longer than 10
min. at full load).
DANGER: Installation or servicing of batteries should be performed or
supervised by personnel knowledgeable of batteries and required
precautions. Keep unauthorized personnel away from batteries.
CAUTION: Wear protective clothing and eye wear.
CAUTION: Batteries can present a risk of electrical shock or burn from high short
circuit current. Observe proper precautions.
CAUTION: Never open or mutilate batteries. Released electrolyte is harmful to the
skin and eyes, and may be extremely toxic.
CAUTION: Battery tray is heavy and can exceed several hundred pounds, insure
you are prepared to move such weight.
CAUTION: Disconnect charging source prior to connecting or disconnecting battery
terminals.
