INSTALLATION INSTRUCTIONS
FOR 1000WPHOTOCELL KIT - PEC500
& REPLACEMENT HEAD-PECH500
GENERAL INSTRUCTIONS
These instructions should be read carfully and retained after
installation for further reference and maintenance.
SAFETY
Before installation or maintenance ensure that the mains supply
to the unit is switched off and the circuit supply fuses are
removed or the circuit breaker is turned off.
It is recommended that a qualified electrician is consulted or
used for the installation of this photocell and installed to the
current edition of the IEE wiring regulations.
INSTALLATION
1. Carefully choose the correct position to install the photocell
kit considering the following guidelines:-
• Where possible there should be a clear view of the sky,
allowing sufficient distance when mounting under eves.
• For optimum performance the position chosen should have
a clear view of north.
• Be away from view of any artificial light source.
• Be away from view of the light source the unit is to control.
• Be inaccessible to unauthorised persons.
2. Securely fix the base holder to a vertical wall so that the head
will be facing up when fitted.
3. Fit the gasket into the base holder foam side up.
4. Enter the supply & load cable into the base through the hole
in the bottom of the base ensuring that a cable gland,
grommet or sealing compound is used to maintain the IP
rating of the unit.
5. Terminate the cable into the NEMA socket observing the
correct connections:‘Li’ = LIVE (supply in)
‘Lo’ = LOAD (supply out)
‘N’ = Neutral
N (Neutral)
L
Lo (Load)
Li (Live)
6. Place the NEMA socket into the base holder with the
arrow printed on the socket pointing towards north, if north
is located behind the unit or towards the mounting surface
then the arrow should be aligned pointing in the direction of
the best natural light.
7. The base holder has 2 locating pins for the NEMA socket to
fit onto, the NEMA socket should then be secured using the
2 countersunk self tapping screws provided.

. Align the largest of the 3 brass feet marked ‘Neutral’ on the
8
photocell head with the largest slot in the NEMA socket,
push the photocell head into the NEMA socket and gently
turn clockwise to lock into place.
OPERATION & TESTING
1. The photocell always powers up in the ‘On’ position, if in
bright daylight it will switch off within 2 minutes, normal
operation will then resume.
2. To test for correct operation cover the photocell with the
packing box, after a short delay, 15 - 120 seconds, the
photocell will operate and power will be applied to the load.
If tested in bright daylight after a similar delay the photocell
will turn off the power to the load when the packing box is
removed.
Q1 The load stays on:-
The photocell is in a shady or dark position or the neutral is not
connected.
COMMON PROBLEMS
Q2 The load is flashing, strobing or switching on and off
repeatedly through hours of darkness:-
The photocell is too close to the light source it is controlling or
‘Li’ & ‘Lo’ are reversed.
