Installation instructions for mains wire-in protectors
Connecting leads should be 10 mm
2
multi stranded
cable for parallel/shunt installation. For series installation,
refer to section 6.
For parallel/shunt installation, keep the connecting leads as
short as possible and ideally less than 25 cm (10 inches) in
length. For series installation, keep earth lead as short as
possible.
This may be better achieved with the equivalent D1R or
D1R/LCD unit with remote display mounting flexibility.
Bind the connecting leads tightly over their entire length.
Before installation
Check that the voltage between neutral and earth does
not exceed 10 volts.
If this voltage does exceed 10 volts, the installation
is unsafe.
Find and rectify the cause of this fault before proceeding.
(For delta supplies with no neutral,
see page 13
).
Make sure that the supply voltage is suitable for the unit.
