6. ELECTRICAL INSTALLATION & CABLING

6.1 INTRODUCTION

• Electrical installation of the equipment should only be carried out by a qualified

electrician following best safety practices at all times.

• The cabling of the Stabiliser has to be sized according to the selected rating of the

Stabiliser.

• The cable size selected should comply with local regulations for installation

requirements.

• While normally all OSES Stabilisers are fitted as standard with an input circuit

breaker, in circumstances where such protection is not incorporated, the Installer

must install suitable circuit protection.

• When the OSES Stabiliser is fitted with an input breaker, care must be taken to

ensure that the supply fuses/breaker is correctly sized to provide tripping

discrimination between the circuit protection devices in the event of a fault.

• Before connecting the unit, it is essential that the mains voltage is verified and the

Stabiliser’s selected output load voltage is in accordance with local / required

requirements.

• Check that the rating of the load shall not exceed the rating of the Stabiliser - as

shown on the unit’s rating plate. The load current should be measured using a true

RMS reading meter.

• To ensure safety and the optimum performance of the Stabiliser, it is imperative

that the machine is properly earthed / grounded.

• When cutting holes for cable entry and glanding care should be taken to ensure

that no swarfs enters the unit. Block off all unused holes.

• In situations where the supply cannot be switched off to facilitate machine

maintenance, it is recommended that a maintenance manual bypass switch is

installed. This will ensure the availability of a direct mains supply for the load whilst

the Stabiliser is being serviced.
