IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important instructions for the Lectro CPR

Uninterruptible Power Supply

(UPS). These instructions should be followed during installation and maintenance of the

power supply, batteries, cabinet, status monitor and any options and/or ancillary equipment.

CAUTION: RISK OF ELECTRIC SHOCK. Hazardous electrical live parts inside the power supply are

energized from the batteries even when the input AC power is disconnected.

CAUTION: An agency-approved service disconnect switch is required at installation and shall be

connected between the utility power source and the CPR power supply. The service disconnect and

service disconnect installation is subject to local electrical codes and should be approved for applica-

tion in a NEMA 3R enclosure, rated 120/240V, with a non-interrupted neutral termination.

For 120 VAC 60 Hz units, the service disconnect shall be a high-magnetic type circuit breaker

rated for 20 amperes in the line lead only.

For 240 VAC units, the service disconnect shall be a 2 pole, high-magnetic type circuit breaker

rated for 20 amperes.

For 220 VAC 60Hz and 230 VAC 50 Hz units, the service disconnect shall be a high-magnetic

type circuit breaker rated for 16 amperes in the line lead only.

CAUTION:

For 120 VAC 60 Hz units, use #12 AWG (minimum) copper, 75°C, for all utility input wiring.

For 240 VAC 60 Hz units, use #12 AWG (minimum) copper, 75°C, for all utility input wiring.

For 230 VAC 50 Hz units, use a minimum of 1.5 mm

(#16 AWG copper, 75°C, for all mains input

wiring).

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

string of four 12Vdc batteries. Please refer to Section 3 of this manual for more details on proper bat-

tery installation, maintenance, storage, and replacement procedures

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

the electrical installer as required by local electrical codes.

CAUTION: The operating temperature range for the Lectro CPR

UPS is –40°C to +55°C for air at

the intake of the CPR module.

CAUTION: CPR UPS installations involving third-party cabinets, not supplied by Lectro, require ade-

quate ventilation, airflow and spacing to insure that the CPR

power supply operates within a tem-

perature range of -40°C to +55°C. Failure to provide an operating thermal environment per published

specifications will void the warranty.
