Installation and Operation

Model EA401

Warnings

•In no case should this telephone apparatus or wiring be installed in a location where acetylene may be present in the atmosphere.

•Two back cover retaining bolts on the model EA401 are factory sealed. Damage to the seals voids the warranty and safety approvals, and may compromise unit safety.

•It is the responsibility of the installer to advise a supervisor if any telephone equipment or wiring in a hazardous location may not comply with regulations and standards applicable to that location.

•Avoid creating a spark by striking tools or metal objects together, against concrete, stone, or any similar substance.

•Test equipment capable of producing an electric spark must not be used in an explosive atmosphere.

•All apparatus should be completely assembled and properly sealed before reconnecting power.

•A EA401 telephone should only be installed with proper authorization. It is necessary for the customer and the telephone company to have a definite agreement regarding the location of the telephone unit, auxiliary apparatus, and protector (i.e. lightning arrestor at the demarcation block).

NOTE:

•To maintain maximum protection, broken or worn parts must be replaced immediately. Any abnormal conditions should be immediately corrected. Periodic inspections are recommended.

•Unless otherwise specified, the customer must provide and install explosion-proof conduit and fittings approved by the Canadian Standards Association (CSA) or listed by Underwriters Laboratories (UL). The customer is also responsible for having the system inspected and approved by the appropriate electrical inspector in accordance with local legal requirements and National Electrical Code Standards.

•EA401 telephone sets and associated external bells and control relays are designed to provide security against ignition of the surrounding atmosphere. All parts of the apparatus which might produce an electrical spark are completely enclosed. All passages to the outside are made such that any spark or flame will be cooled to a temperature below the ignition threshold before reaching the outside atmosphere.

•If the handset or cord is damaged, it must be replaced with part EA10H handset assembly. Handsets and cords are not covered under warranty other than to be free of defects at time of installation.

•If the telephone is found to be defective or in need of repair, it must be returned to the manufacturer. No field repair is possible other than replacement of the handset and fuse.

•Telephones in good condition may be moved from one location to another.
