ELECTRICAL INSTALLATION CONSIDERATIONS

This UPS must be installed by competent electrical personnel and wired in accordance with local/national electrical codes.

The following information is provided for your guidance.

WARNING

HIGH EARTH LEAKAGE CURRENT- EARTH CONNECTION IS ESSENTIAL BEFORE CONNECTING THE MAINS SUPPLY. Earth in accordance with local electrical codes.

CAUTION

This UPS is fitted with EMC suppression filters. Earth leakage exceeds 35mA. Transient and steady state earth leakage currents, which may occur when starting the UPS, should be taken into account when selecting instantaneous RCCB or RCCD devices. Note also that the earth leakage currents of the load will be carried by this RCCB or RCCD.

WARNING

This UPS does not incorporate automatic backfeed protection. A warning label must be fitted to all primary power isolators stating:

ISOLATE UNINTERRUPTIBLE POWER SYSTEM BEFORE WORKING ON THIS CIRCUIT.

On start-up, the UPS will take a half cycle inrush current of up to 3 times the rated current. This must be taken into account when selecting the overload protection device at the input mains supply distribution point. To avoid random tripping on start-up, we recommend that the input mains supply be protected with an MCB capable of withstanding this initial inrush. An MCB specified as being “TYPE 4” (British standard) or “CURVE D” (IEC standard) is suitable for this purpose.

The mains input supply cable must be connected to the UPS via a wall mounted double pole circuit breaker, rated to carry the current in table 1 and be capable of breaking the maximum prospective short circuit current of this branch circuit. The breaker is to be mounted within two metres of the UPS and be readily accessible to the operator.
