Introduction; General Safety Messages And Warnings; Installation; Access To Terminals - Eaton PH1 Manuel Technique

1.0 Introduction

These manual fire alarm pull stations have been designed
for use in hazardous locations and harsh environmental
conditions. The GRP enclosures are suitable for use
offshore or onshore where light weight combined with a
high level of corrosion resistance is required.
2.0 General safety messages and
warnings
All instructions and safety messages in this manual must
be followed to allow safe installation of the device. The
device must only be installed and maintained by correctly
trained site personnel/installers.
I. To reduce the risk of ignition of hazardous
atmospheres and shock, do not apply power to the
device until installation has been completed and the
device is fully sealed and secured.
II. To reduce the risk of ignition of hazardous
atmospheres and shock, keep device tightly closed
when the circuit is energised.
III. Before removing the cover for installation or
maintenance, ensure that the power to the device
is isolated.
IV. Following installation, test the device to ensure
correct operation.
V. Following installation ensure a copy of this manual is
made available to all operating personnel.
VI. When installing the device, requirements for
selection, installation and operation should be
referred to e.g. IEE Wiring Regulations and the
'National Electrical Code' in North America. Additional
national and/or local requirements may also apply.
VII. Cable termination should be in accordance with
specification applying to the required application.
MEDC recommends that all cables and cores should
be correctly identified. Please refer to the wiring
diagram in this manual (or separate diagram provided
with the unit).
VIII. Ensure that only the correct listed or certified cable
glands are used and that the assembly is shrouded
and correctly earthed.
IX. Ensure that only the correct listed or certified
stopping plugs are used to blank off unused gland
entry points and that the NEMA/IP rating of the unit
is maintained.
X. MEDC recommend the use of a sealing compound
such as HYLOMAR PL32 on the threads of all glands
and stopping plugs in order to maintain the IP rating
of the unit.
XI. The internal earth terminal, where fitted, must be
used for the equipment grounding and the external
terminal, if available, is for a supplementary bonding
connection where local codes or authorities permit or
require such a connection.
XII. When installing the device, MEDC recommends the
use of stainless steel fasteners. Ensure that all nuts,
bolts and fixings are secure.
XIII. The pull station should not be mounted closer than
40mm to any solid object which does not form part
of the unit.
XIV. When fitting or removing cable entry glands, the
cable entry inserts must be held with a suitable tool
to prevent movement.

3.0 Installation

The unit is mounted via 4 off Ø6.5mm fixing holes in the
base of the enclosure. The unit has been designed and
certified to operate at any attitude.
The fixing holes have been designed to accept an M6
screw or bolt.

Access to terminals

Unscrew the 4 off M6 screws (5.0mm A/F hexagon
key) holding the cover assembly to the base. The cover
screws are retained in the cover assembly for ease of
installation. Gently lift the cover assembly away from the
base of the enclosure to gain access to the interior.
Once termination is complete, carefully replace the cover
assembly back onto the base of the enclosure, avoiding
damage to the mating surfaces. Ensure the o-ring is
correctly seated in its groove during re-assembly. Evenly
tighten the 4 off M6 screws (5.0mm A/F hexagon key).
Ensure the required gap (0.10mm Max.) is maintained
between the cover and the base.
