also example on page 1.
Product installation must be carried out in accordance with
any local codes that may apply and should only be carried
out by a competent electrical engineer.
Location
The location of the unit should be made with due regard to
the area over which the beacon warning signal must be
EX-TECH SAS-12-BC-TM REV02
visible. The unit should only be fixed to services that can
carry the weight of the unit.
Mounting
The product should be mounted on a vertical surface using
4 fixing holes in the base. The fixing holes are designed to
fit M5 Allen Screw only. Use of stainless steel fastener is
recommended by EX-TECH SAS. The Beacon can be
operated in any attitude. If you need mounting plate,
please contact EX-TECH SAS for the installation drawing
of the mounting plate.
6.0 WIRING
General Requirement
EX-TECH SAS recommends that all cables and cores
should be fully identified (suggest using cable from 2.0 to
2.5 mm²). Ensure that all nuts, bolts and screws are
secured. Ensure that only the right and certified cable
glands are used and earthed correctly. Ensure that only
the right and certified stopping plugs are used to blank off
unused gland entry points. In order to maintain the IP
rating of the product, we recommend SS316L for this
application.
Cable Connection
The cable connection is connected with the 3-hole terminal
BC 125
blocks marked POWER IN located in the flameproof
enclosure (See Fig 2).Cable connection should be carried
out in accordance with relevant technical requirement.
