WP7 PB/PM/PT CALL POINTS
1) Certification & Ratings
All units have a rating label, which carries the following
important information: -
Model No.: WP7-PB-S (Single Switch)
WP7-PB-D (Dual Switch)
WP7-PM-S (Single Switch)
WP7-PM-D (Dual Switch)
WP7-PT-S (Single Switch)
WP7-PT-D (Dual Switch)
UKCA Marking
IP Rating: IP66/67 to EN/IEC60529
Ambient Temperature Range: -55°C to +75°C
2) Location and Mounting
The location of the call point should enable ease of access
for operation and testing. The unit should be mounted using
the 4 off fixing holes which will accept up to M5 sized fixings.
They should only be fixed to services that can carry the
weight of the unit.
To gain access to the mounting holes in the base the front
cover must be removed. See Section 3.

Ø6,4 [Ø0,25in.]
Fig. 1 View of base unit showing fixing centres (in mm).
3) Access to the Enclosure
To access the chamber, remove the four off M6 x 50
stainless steel cap head cover bolts
Once the screws are removed the cover will hang down out
of the way to gain access to the terminals, the internal earth
terminal and mounting hole recesses.
Fig. 2 Accessing the Explosion proof Enclosure.
Check that the earth bonding wire between the two castings
is secure and the ‘O’ ring seal is in place.
4) Earthing
The units are provided with internal and external earth
terminals which are mounted in the base of the unit.
Internal earthing connections should be made to the Internal
Earth terminal in the base of the housing using a ring crimp
terminal to secure the earth conductor under the earth clamp.
The earth conductor should be at least equal in size and
rating to the incoming power conductors.
When using the internal earth terminal ensure that the
stainless steel M4 flat washer is between the incoming earth
wire and the enclosure.
Warning – High voltage may be present,
risk of electric shock. DO NOT open
when energised, disconnect power
before opening.

Inductive Load 3.0A Max
DC voltage 12V Max Current 5.0A Max
Electrical connections are to be made into the terminal blocks
/ DIN rail provided. See Section 8 for wiring options.
6) Selection of Cable. Cable Glands, Blanking
Elements & Adapters
The cable gland entries have an M20 x 1.5 entry thread.
The WP7 Call Point range can be supplied with the following
types of adapters:
M20 to ½” NPT
M20 to ¾” NPT
M20 to M25
7) Cable Connections
Electrical Connections are to be made into the terminal
blocks using solid or stranded wire. See section 3 of this
manual for access to the enclosure.
Wires having a cross sectional area between 0.5 mm² to
2.5mm² (AWG 20 – 14) can be connected to each terminal
way.
If an input and output wire is required the 2-off Live/Neutral or
+/- terminals can be used. If fitting 2-off wires to one terminal
way the sum of the 2-off wires must be a maximum cross
sectional area of 2.5mm².
Strip wires to 8mm. Wires may also be fitted using ferrules.
Terminal screws need to be tightened down with a tightening
torque of 0.45 Nm / 5 Lb-in.
When connecting wires to the terminals great care should be
taken to dress the wires so that when the cover is inserted
into the chamber the wires do not exert excess pressure on
the terminal blocks. This is particularly important when using
cables with large cross sectional areas such as 2.5mm².
8) Wiring Unit
The units come with two options for the terminal block.
A DIN rail version which has 8-way connection and allows for
full configuration at factory or limited wiring of EOL devices by
customer.
The PCB Terminal Version has a 6-way connector but is
designed to allow for full configuration with Series and EOL
devices in a number of wiring configurations.
For EOL and Series device limitations and configurations see
Section 9.
For full wiring details see wiring schematic D234-06-001.
Wiring Connections for 8-Way DIN Rail
Fig. 4 DIN Rail in Base
Wiring Connections For 6-Way PCB Terminal Board
Fig. 5 PCB Terminal Block in Base
See section 9 and pages 5, 6 & 7 for details of adding Series
and EOL devices on the PCB. This can either be done at the
order stage or added to the correct terminal blocks afterward.
9) End-of-Line and Series Devices
All models can be fitted with series resistors, end-of-line
monitoring resistors, monitoring diodes, zener diodes and
also specific customer modules if supplied with direct current
up to 50Vdc.

The unit can be wired with a maximum of 4 module devices.
Please refer to wiring schematic D234-06-001
When customer is fitting EOL or Series device ensure device
leads are insulated or routed so not to create an electrical
short.
10) Testing unit operation
The push button types -PB -PT and -PM are all operated by
pressing in the main plunger down activating the switch.
The -PB plunger needs to be firstly twisted by 90 degrees
clockwise to position shown and then pressed in.
Fig 6 -PB Version Twist and Push Action
The -PM and -PT need to have the protective flip lid opened
first and then the main plunger pressed in.
Fig 7 -PT & -PM Versions Push Action
On –PM versions the operation is momentary and as such
the plunger will reset automatically once the pressure on the
plunger is released.

On -PB the plunger will remain in the down position until the
unit is reset. This is done by pulling the plunger back up to
the start position shown in fig 6. Then the plunger is twisted
back 90 degrees anti-clockwise to the stop.
On -PT the plunger will remain in the down position until the
unit is reset. This is done by lifting the plunger back up using
the tool reset key provided.
