Cautions

NOTE: Enclosure, equipment or parts may be damaged or cause damage if used

or installed improperly.

To avoid damage:

• Prior to installation, verify that the AC input voltage to the enclosure and its equipment

match with respect to voltage and frequency.

• Prior to installation, verify that the output voltage from the enclosure or its equipment match

the voltage requirements of the connected equipment (load).

• Prior to installation, verify that the enclosure’s utility service panel is equipped with a

properly rated circuit breaker for use with the equipment inside. Refer to manufacturer’s

recommendations.

• Review and upgrade utility service panel circuit breaker requirements whenever the

equipment within the enclosure is changed.

• Prior to installation, contact local utilities, local building maintenance departments, and

cable/piping locator services to ensure that installation does not interfere with existing utility

or building cables/piping.

• Do not exceed the output rating of equipment. Verify load requirements prior and during

connection process.

• Prior to handling the batteries, touch a grounded metal object to dissipate any static charge

that may have developed on your body.

• Alpha Technologies is not responsible for unit damage due to enclosure or installation

temperatures which exceed the operating temperature of the product.

• The Lectro CPR UPS is a 36 or 48Vdc system designed for use with either a single or dual

string of three or four 12Vdc batteries. Please refer to Section 3 of this manual for more

details on proper battery installation, maintenance, storage, and replacement procedures

• Over current protection and disconnecting means for the AC output are to be supplied by the

electrical installer as required by local electrical codes.

• The operating temperature range for the Lectro CPR

UPS is –40°C to +55°C for air at the

intake of the CPR module.

• CPR UPS installations involving third-party cabinets, not supplied by Lectro or Alpha, require

adequate ventilation, airflow and spacing to ensure that the CPR

power supply operates

within a temperature range of -40°C to +55°C. Failure to provide an operating thermal

environment per published specifications will void the warranty.
