Installing the Kit PSU7A Assembly in a Remote Enclosure (Continued)
IF PSU7A IS A REPLACEMENT FOR 'OLD' VERSION WITH INTEGRAL
MAINS LEAD: Remove the existing mains terminal block and use its
screw to fit terminal block of mains cable PN: 082-254-001 in its place.
The cable has a factory-fitted clip which must be affixed to the side wall of
the enclosure. YOU MUST ALSO MAKE THE SAFETY EARTH
CONNECTION (I to L).

Mains and Safety Earth Wiring
Connections
WARNING. Risk of electric shock. Before working
on mains connections, ensure the mains power
supply to the enclosure is disconnected.
! !
Segregate mains wiring from all other wiring.
TRANSIT CABLE CLIP: Before proceeding, CAREFULLY cut
the cable clip that secures the ferrite cable loop to the front of
the enclosure (at the ventilation grille). DO NOT cut the cable
clip that secures the mains cable to the side of the enclosure.
1
Make/check the following safety earth connections:
Safety earth connection between terminal block (I) and
earth blade connector (L).
2
WARNING: It is vital that the main panel has a safety
earth connection which may be connected to a
convenient safety earth bonding point.
3
The 230VAC mains input wiring (H) must be terminated at the
mains termination block (I) in the top left-hand side of the
Battery/PSU Enclosure. The PSU mains cable (E) is factory-
fitted to the termination block. Push the mains cable's
connector into the socket of the PSU7A. Pull tight the cable
clip at the side of the enclosure.
Note: Connections to the DTP/Booster module kit are shown
on the instruction sheet (997-267-000-X) supplied with
that kit.
Note: All blade connections to earth incorporate a locking
barb. To make a connection push the shrouded
receptacle on to the earth blade (1). To remove this
connection, pull the shroud (2), NOT the earth wire.
Ratings Label
When the PSU7A is installed in the Remote Battery/PSU
Enclosure, the ratings label (PN: 345-405) supplied in the
PSU7A Kit must be attached to the Enclosure as follows:
1 Four cross-hairs (N) are provided for guidance in
positioning the ratings label (O) on the right-hand side wall
of the remote enclosure (when viewed from the front).
Ensure this area is free of grease and/or dust.
2 Ensure the correct orientation of the ratings label. Partially
remove backing paper and offer the exposed area to the
indicated location (P) on the enclosure side wall.
3 Align the end of the label where the backing paper has
been pulled clear with one pair of vertically-placed cross-
hairs to start the application to the side wall. Gradually
remove the rest of the backing paper, gently applying
pressure to the label as you proceed until the other end of
the label is reached.
4 To ensure sufficient adhesion has occurred, cover the label
with the removed backing paper and apply pressure over
the whole area of the label using, for example, your finger -
DO NOT use any object capable of marking or defacing the
ratings label.
