1.INTRODUCTION

1.1Safety Precautions

This equipment has been designed and tested to the highest safety standards. The following precautions should be covered to ensure safe operation of the apparatus.

1.2Transportation and Storage

Careful inspection of the unit must be made after it has been subject to transportation or storage. Any serious damage, which could render it dangerous, must be acted upon to safeguard any potential user.

1.3Mains Connector and Plug

The supply lead plug shall only be inserted into a supply socket equipped with an earth contact. Extension of the lead must include a suitable conductor for the protective earth.

This equipment must be earthed.

CSA requirements

1)"The socket outlet shall be installed near the equipment and shall be easily accessible"

2)"The Telephone Hybrid utilizes a AC power source; 90-250Vac, 50-60Hz, 0.25 Amps per cord"

1.4Fuses

Only the specified value and type of fuse must be fitted in the event of a replacement.

The brown supply lead (live) is fitted with a series fuse located in the mains connector fitted on the rear panel. Should the unit be fitted with a two-pin plug then it is possible, if the supply is reversed, for parts of the equipment to remain at supply potential after the fuse has ruptured.

1.5Removal of Covers

Care must be exercised if the covers of the unit are removed. All internal live parts are covered but the equipment should be disconnected from the supply source before repair or maintenance.

Should it be necessary to carry out adjustments with the supply voltage connected then this work must be done by suitably qualified personnel.

Note that capacitors in power supplies and mains filters can be charged when the equipment is disconnected from the supply. Before commencing work on the unit, these components should be discharged in a safe manner.

It is important to note the designation of securing screws. These must be replaced in the positions to which they were supplied to reduce the possibility of damage to circuit boards mounted close to chassis securing screws.
