3. INSTALLATION

3.2

Connecting the CFR (Plug and receptacle)

CAUTION: Installation and wiring should be performed by qualified service
personnel in accordance with applicable electrical codes. Verify that the
main utility panel is switched off before proceeding. Mark all circuit breakers
supplying the UPS.

1. Connect a dedicated ground wire from the GROUND lug on the back of the CFR

to an electrical ground point (i.e., wall receptacle gound or a copper water pipe).
The wire size must be at least 14 AWG (2.0 mm

) , be rated 75

C minimum,

and have green insulation provided with one or more yellow stripes.

NOTE: Most electrical codes require this type of ground connection in
case the AC Line power cord is disconnected from the wall. Always consult
your local electrical code to ensure prescribed grounding practices.

2. Connect the CFR’s AC power cord to the receptacle.

3. If using an external battery pack, plug its connector into the rear panel of the

UPS (see section 3.3).

NOTE: ALL rack mount units require an external battery pack. Before
attempting to operate these units without a battery pack, contact Alpha
Technologies for additional information.

4. Start and test the UPS without the load connected (see section 4.1). After

testing, switch the unit OFF before connecting the load.

5. Plug the equipment to be protected into the UPS rear panel receptacles.

NOTE: The load should be switched OFF prior to connection.

Set Inverter Alarm Delay:

0-5 minutes
(default value is “0”; UPS003 and UPS004 are send immediately)

Transmission of the “UPS003 - inver ter on” message can be

delayed for 1 to 5 minutes to prevent short interruptions in the AC line
from being displayed. Setting this value to “0” causes UPS003 message
to be sent immediately. If the line returns and the CFR switches back to
the line mode before this delay time expires, then neither UPS003 or
“UPS004 - line mode” messages are sent for the event.

Set DIAL1 Phone Number:

dial command, 20 characters or less
(default value is “ATDT 234-5678”)

This command sets the modem command for DIAL1 action. The

CFR sends this string to the modem to initiate a DIAL1 action.  The string
should start with “ATDT”, and is followed by the phone number where
DIAL1 events are being sent.  You can use all the dial command options
such as “,” and “W”  (refer to your modem manual).

Set DIAL2 Phone Number:

dial command, 20 characters or less
(default value is “ATDT9,1-123-456-7890”)

This command sets the modem command for DIAL2 action. The

CFR sends this string to the modem to initiate a DIAL2 action. The string
should start with “ATDT” and is followed by the phone number where DIAL2
events are being sent. You can use all the dial command options such as
“,” and “W” (refer to your modem manual).

Set Location ID:

user defined location ID, 20 characters or less
(default value is “CFR UPS in RM 123”)

This command sets the modem location ID. The modem location

ID is included as the first line of any event message that is sent by the
CFR. You may use this feature to define a location ID or a name for every
CFR. This enables you to distinguish where and from which unit a message
is coming from.
