Installation & Operating Instructions
1. General Information
These instructions should be read carefully and retained
for further reference and maintenance. The Timeguard
range of RCDs, provide protection against fire hazard and
rapid double pole disconnection from electric shock for the
appliance connected to it. They fully comply with BS7288
and BS1363-4 (including updates and amendments).
They are designed to mount on either a BS4662 recessed
box or a BS5733 surface mount box (plastic versions only).
Note: RCD – Residual Current Device.
2. Safety
• Before installation or maintenance, ensure the mains
1
supply to the RCD fused connection unit is switched off
and the circuit supply fuses are removed or the circuit
breaker turned off.
• It is recommended that a qualified electrician is
consulted or used for the installation of RCD fused
connection unit and install in accordance with the
current IEE wiring and Building Regulations.
• Check that the total load on the circuit including when
this RCD fused connection unit is fitted does not exceed
the rating of the circuit cable, fuse or circuit breaker.
• Electricity can be dangerous, use of an RCD should
not be regarded as a substitute for basic electrical
safety precautions.
• Always test the RCD before use. If the test procedure
is not completed satisfactorily or an appliance continues
to trip the RCD seek professional advice and switch off
the appliance.
• To clean use a dry cloth only.
Do NOT use any liquid cleaners.
• The RCD should NOT be used when it could come into
contact with liquids or excessive atmospheric pollution.
• A warming of the casing during use is normal.
• Do NOT use outside the service conditions.
• For devices having a solid neutral, ensure the correct
polarity of the incoming supply connections should the
device trip automatically upon connection to the supply.

3. Wiring Tests – IMPORTANT
• Remove this product from the circuit if carrying out tests
(as described in the IEE Wiring Regulations) for earth
loop impedance, prospective short circuit current
and insulation resistance.
• Use the enclosed wiring label to ensure this is
carried out.

6. Installation
• The RCD should form part of a 30A ring main or
terminate a spur off a 30A ring main. The cable
connecting the supply to the RCD should be either:
2x 2.5mm² for the ring main or 1x 2.5mm for the spur.
• Fit the appropriate BS1362 fuse to suit the load
appliance to be connected.
• The cable connecting the load appliance should be rated
according to the fuse fitted to the connection unit.
• Make sure to tighten all screw terminals onto
exposed wires.
• Ensure that there is both sufficient length of the supply
cable tails(s) to enable easy wiring.
6.1 Ensure the mains supply is switched off and the circuit
7
supply fuses are removed or the circuit breaker turned off.
6.2 Connect the incoming 230V 50Hz supply and outgoing
load cables to the relevant terminals ensuring correct
polarity is observed and that all bare conductors are
sleeved (see section 7. Connection Diagrams).
6.3 A front cable exit cut-out is provided on the RCD10WPVN
and RCD11WPVN units. The RCD10WPVN has a preinstalled removable blanking plate and the RCD11WPVN
front cable exit needs to be cut-out manually.
6.4 If the front exiting cable cut-out is required:-
1. Cut-out the front cable exit or remove the blanking
plate (you can discard the blanking plate at this stage).
2. Remove the cable grip and clamp screw from the
accessory pack.
3. Secure the load cable to the unit using the cable clamp
and clamp screw.
6.5 Finally secure the unit to the back box with the fixing
screws provided, forming the cables during installation
to avoid any entrapment and cable damage.
Do not over tighten.
RCD16MLN Metal Clad Back Box
6.6 Note the correct orientation of the back box
(the word TOP should be the correct way up).
6.7 Lock rings, with a maximum thickness of 4.2mm and
a maximum diameter of 25.7mm must be used on the
inside of the back box. The gland or conduit must not
project into the back box beyond the lock ring, a male
8
adapter should be used within the back box along with
a female coupler on the outside to terminate the cable
glands or conduit.

Note: Always test the RCD before use
12
To Test
8.1 RESET – Press the Grey/Blue Reset button marked (R),
the status indicator should show Red.
8.2 TEST – Press the Red Test button marked (T), the status
indicator should show Green. This indicates the RCD
had been tripped and power has been disconnected.
8.3 RESET – Press the Grey/Blue Reset button marked (R)
again, the status indicator should show Red.
• If all the above operations work satisfactorily,
the RCD is safe for use.
• If the procedure is not completed satisfactorily,
DO NOT use the RCD and see professional advice.
• In applications such as hand driers it may not be
practical to expect each user to test before use. In this
case we suggest an appropriate person applies the test
routine twice a day.
To Use
• After satisfactorily testing the RCD, any connected
appliance may be switched ON, and used in confidence
that the use is protected from electric shock by rapid
disconnection.
If the RCD Trips
13
• Turn the appliance switch OFF, press the Grey/Blue Reset
(R) button and note that the status indicator turns Red.
Switch the appliance ON and of the RCD trips again,
switch OFF the appliance and DO NOT use it, as it may
be faulty. Seek professional advice.
