A. INTRODUCTION<br />
Congratulations on the purchase of another quality <strong>MK</strong> product.<br />
The Masterseal range consists of surface mounted switches, 13A<br />
socket outlets, a photo-electric switch, an RCD protected socket<br />
outlet and enclosures to accommodate various modules.<br />
The various modules comprise 10A and 20A switches, 240V and 24V<br />
neons.<br />
Switches and enclosures are provided with a fluorescent locator<br />
neon that remains lit regardless of the switch position.<br />
Made from a tough thermoplastic material, the Masterseal range of<br />
products are robust and suitable for use indoors and outdoors,<br />
wherever corrosion resistance, dirt and moisture proofing is required.<br />
All products accept <strong>MK</strong> push-in conduit and cable entries, which<br />
compliment the range (see Service Items).<br />
Switch products and enclosures meet a rating of IP56.<br />
If you are in any doubt regarding the application or installation of this<br />
product, please contact <strong>MK</strong> Technical Sales Service Department on<br />
01268 563720 or your local <strong>MK</strong> Representative.<br />
D. INSTALLATION<br />
2<br />
NOTES:<br />
1. The enclosure should only be mounted in the vertical plane on a<br />
flat surface from which all grease, dirt and loose material has<br />
been removed.<br />
2. Position back box ensuring that one of the drain hole features is<br />
located at the bottom left hand corner.<br />
3. Prior to mounting the enclosure, the blank fitted at the required<br />
cable entry, should be removed and replaced with the desired<br />
conduit entry or coupler (see Service Items).<br />
4. If conduit enters from the top or side of the enclosure, the drain hole<br />
must be drilled out using a 5mm diameter drill bit, to allow any<br />
condensation formed in the conduit system to drain out of the unit.<br />
Opening of the drain hole will reduce the IP rating, therefore ensure that<br />
jetted water is not directed at the unit if the drain hole is used.<br />
5. Drain holes should not be drilled out if the product is to be<br />
located in an excessively dusty environment (eg. a sawmill). Only<br />
bottom conduit entry should be used.<br />
6. If conduit enters from the bottom of the enclosure, and it is<br />
necessary for the IP rating of the product to be retained, a<br />
condensate hole of at least 5mm diameter must be provided at<br />
the lowest point of the conduit run.<br />
4. Using the dimensions in Fig. 2, mark the positions of the screw<br />
fixing holes ensuring that conduit or cable is aligned with the<br />
appropriate centre line on the diagram.<br />
5. Drill the screw fixing holes to accept an appropriate wall fixing.<br />

7. Metal conduit can be earthed using the earth lead adaptor<br />
(see Service Items).<br />
8. If wiring directly into the unit without using conduit ensure that<br />
a cable specified for outdoor use is used with the cable entry.<br />
9. PVC cable entry should only enter from the bottom of the enclosure<br />
using the cable entry.<br />
10. If used, conduit must be sealed to the conduit entry using a nonsetting<br />
conduit adhesive such as Egaweld No. 2. It is not<br />
necessary to apply adhesive to the enclosure/conduit joint.<br />
11. A locator is provided on all switch products and is intended to<br />
remain lit at all times regardless of the switch position, if wired<br />
as shown in Fig. 5, page 16. Replacement locators are available<br />
(see Product Range list for details).<br />
12. Use No. 8 wood screws for fixing box to wall.<br />
13. WARNING: Do not allow any form of paint or wood<br />
preservative to come into contact with any part of these<br />
products, as they may damage the plastics used.<br />
These products can safely be mounted on surfaces coated<br />
with paint/preservative when they are dry.<br />
WARNING: ALWAYS ENSURE THAT THE MAINS SUPPLY IS<br />
DISCONNECTED BEFORE COMMENCING WORK.<br />

SWITCH MODULES<br />
Procedure for Installing Modules<br />
Notes:<br />
1. The modules are intended to be installed once only. If removed<br />
from the front plate and re-installed the effectiveness of the snap<br />
fit will be impaired and may reduce the performance of the<br />
product.<br />
2. If the membrane seal is not in the correct position the IP rating<br />
of the product may be affected.<br />
Once you have decided on the type of enclosure and modules you<br />
wish to use, proceed as follows:<br />
1. Remove the front plate from the enclosure.<br />
2. Clip the required modules onto the front plate from the back<br />
ensuring that the “TOP” marking on the module is adjacent to<br />
the “TOP” marking on front plate (see Fig. 3). When fitting a<br />
single module, this should be fitted on the left hand side (as<br />
viewed from the back).<br />
3. Ensure that the module clips are securely latched to the lugs on<br />
the rear of the front plate (see Fig. 3).<br />
