Installation
Consumer units
The Consumer units are provided with
internal busbar shields.
Front covers have lockable lid (using barrel
lock & key accessory K5593s), which masks
the front cover retaining screw. Removal of
the front cover for internal access requires
the use of tools.
Cover mounted blanks are provided with
each Sentry Consumer unit to fill unused
ways.
4,8 and 12 module – 2 off x 1
16 and 21 module – 2 off x 2
If additional unused ways are required the
DIN rail mounted blank 5544s must be used
to complete the installation.
Two/four module enclosures
Front covers require tools to enable removal
and gain internal access.
5604s has provision for tamper-proofing.
Note: Only the K5592s enclosure will accept
the one module RCBO’s.
Service conditions
Wiring of these products must comply with
current IEE regulations.
Consumer units and two and four module
enclosures are intended for indoor use in dry
conditions and are not suitable for locations
where high humidity and/or high tempera-
tures may be experienced.
It is important that during installation of any
Sentry enclosure, steps are taken to ensure
that the IP rating is maintained, e.g. correct
use of cable glands and knockouts/cutouts.
Testing
Site assembled consumer units using MK
components comply fully with BS EN 60439-3
so do not require further site testing other
than normal routine installation tests.
Split load and multi-incomer
arrangements
Such assemblies must utilise the relevant Sentry
kit in order to comply with BS EN 60439-3 and
to avoid the need for additional testing.
Stacking kits
Accessory kits (stacking frame, fittings and
earth cable) can be used to produce stacked
dual rail units in the insulated and surface
metal ranges for the 12, 16 and 21 module
units.
K6061s – for 12 module units to create
24 module dual rail consumer unit.
K6062s – for 16 module units to create
32 module dual rail consumer unit.
K6063s – for 21 module units to create
42 module dual rail consumer unit.
Weatherproof enclosures
The weatherproof enclosures may be used for
outdoor applications up to the level of the
IP65 rating.
The cable entry position on the top and
bottom of the enclosure is at the discretion of
the installer and can be achieved with suitable
tools. Knockouts/cutouts are provided for
side entry.
Precautions must be taken to maintain the IP
rating, e.g. correct use of cable glands and
knockouts. The caps provided must be used to
cover the mounting screws.
Note: IP65 rating only achieved with lid in the
closed position.
These enclosures will not accept the one
module RCBOs.
