Emerson 200, U/300/S/12P, U /400/S/12P, U/300/S/6P, U /400/S/6P, 400KVA, 160 Safety Precautions

Safety Precautions

Conformity and standards

This equipment complies with the following requirements:

Normative references: Uninterruptible Power System (UPS).

zIEC60950-1, IEC62040-1-1 — General and safety requirements for use in operator access area

zIEC/EN62040-2 — EMC requirements

zIEC62040-3 — Performance requirements and test methods

Continued compliance requires installation in accordance with these instructions and the use of manufacturer approved accessories only.

Warning

HIGH EARTH LEAKAGE CURRENT: EARTH CONNECTION IS ESSENTIAL BEFORE CONNECTING THE INPUT SUPPLY.

This equipment must be earthed in accordance with local electrical codes.

Warning

Upstream power distribution protection device of the UPS must be selected according to local electrical codes.

Warning

If any internal fuse of the UPS is damaged, it must be replaced by professionals with a new one of the same specifications.

Caution

This equipment is fitted with radio frequency interference (RFI) suppression filters. Earth leakage current exceeds 3.5mA and is less than 1000mA.

Transient and steady-state earth leakage currents, which may occur when starting the equipment, should be taken into account when selecting instantaneous residual current circuit breaker (RCCB) or residual current detector (RCD) devices. RCCBs must be selected insensitive to DC unidirectional pulses (Class A) and transient current pulses.

Note also that the earth leakage currents of the load will be carried by this RCCB or RCD.

Warning

This system has a signal available for use with an automatic device, externally located, to protect against backfeeding voltage through the mains Static Bypass circuit. If this protection is not used with the switchgear that is used to isolate the bypass circuit, a label must be added at the switchgear to advise service personnel that the circuit is connected to a UPS system.

The text is the following or equivalent:

ISOLATE THE UNINTERRUPTIBLE POWER SYSTEM BEFORE WORKING ON THIS CIRCUIT.

General

As with other types of high power equipment, dangerous voltages are present within the UPS and battery enclosure. The risk of contact with these voltages is minimized as the live component parts are housed behind a hinged, lockable door. Further internal safety screens make the equipment protected to IP20 standards.

No risk exists to any personnel when operating the equipment in the normal manner, following the recommended operating procedures.

All equipment maintenance and servicing procedures involve internal access and should be carried out only by trained personnel.
