CONNECTING THE UPS TO AN AC SOURCE
1. When connecting the UPS to the utility power and the load, it is recomme-
nded that you install the protective devices. The protective devices should
be approved components that meet safety certifications.
2. Prior to applying power to the UPS, ensure the UPS is properly grounded.
3. The utility power for the UPS must be single-phase in accordance with its
rating label and the specifications in this manual.
The ED5000RT-CU and ED6000RT-CU come with an input power cord in the
box. The #10 AWG input power cord is 10ft long and has an L6-30P plug on it.
Connect the UPS to a two pole, three wire, grounded AC wall outlet. The outlet
must be connected to the appropriate branch protection (circuit breaker).
Connection to any other type of outlet may result in a shock hazard and violate
local electrical codes. The AC wall outlet shall be installed near the UPS and
shall be easily accessible. The plug on the input power cord on this UPS
series is intended to serve as a disconnect device. Do not use extension
cords, adapter plugs, or surge strips. The installation of upstream and down-
stream protective devices is highly recommended when the UPS is connected
to the utility power and the load.

1. The UPS MUST be in the off position.
2. The DC breaker(s) on the rear panel of the Battery Pack(s) MUST be in
the off position.
3. Remove the External Battery Connector's cover plate from the rear panel
of the UPS (requires a phillips screwdriver).
4. Remove the top External Battery Connector's cover plate from the rear
panel of the Battery Pack.
5. Connect the one end of the #8 AWG premolded battery cable to the Exter-
nal Battery Connector on the rear panel of the UPS and secure with the
retaining screws.
6. Connect the other end of the #8 AWG premolded battery cable to the Exte-
rnal Battery Connector on the rear panel of the Battery Pack and secure
with the retaining screws.
7. See the Battery Pack User's Manual for more detailed information.
CAUTION:
The battery can present a risk of electrical shock. These batteries
produce sufficient current to burn wire or tools very rapidly, producing molten
metal. Observe these precautions when installing or replacing the batteries:
1. Remove watches, rings, or other metal objects.
2. Use hand tools with insulated handles.
3. Wear protective eye gear (goggles), rubber gloves and boots.
4. Do not lay tools or other metal parts on top of batteries.
5. Disconnect the charging source prior to connecting or disconnecting the
battery terminals.
6. Determine if the battery is inadvertently grounded. If the battery is, rem-
ove the source of the grounding. Contact with any part of a grounded ba-
ttery can result in an electrical shock. The likelihood of such shock will be
reduced, if such grounds are removed during installation and maintenance.
WARNING:
This UPS series does not have internal batteries. A Battery Pack
MUST
be connected to these UPSs so that they will provide battery backup for
the connected load.
NOTE:
See the Battery Pack User's Manual for more detailed information.
