•
To ensure fire protection, replace the fuse only 
with the specified type and rating. 
•
Disconnect the power cord before fuse 
replacement.

Make sure the cause of fuse blowout is fixed 
before fuse replacement. 
Cleaning SPD-
3606 
•
Disconnect the power cord before cleaning.
•
Use a soft cloth dampened in a solution of mild 
detergent and water. Do not spray any liquid. 
•
Do not use chemical or cleaner containing harsh 
material such as benzene, toluene, xylene, and 
acetone. 
Operation 
Environment 
•
Location: Indoor, no direct sunlight, dust free, 
almost non-conductive pollution (Note below) 
•
Relative Humidity: < 80%
•
Altitude: < 2000m
•
Temperature: 0°C to 40°C
(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees 
and their requirements as follows. SPD-3606 falls under degree 2. 
Pollution refers to “addition of foreign matter, solid, liquid, or 
gaseous (ionized gases), that may produce a reduction of dielectric 
strength or surface resistivity”. 
• Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
• Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused 
by condensation must be expected. 
• Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to 
condensation which is expected. In such conditions, equipment 
is normally protected against exposure to direct sunlight, 
precipitation, and full wind pressure, but neither temperature 
nor humidity is controlled.

Power cord for the United Kingdom
When using SPD-3606 in the United Kingdom, make sure the power 
cord meets the following safety instructions. 
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with 
the following code: 
Green/ Yellow: 
Earth
Blue: Neutral 
Brown: Live 
(Phase)
As the colours of the wires in main leads may not correspond with the 
colours marking identified in your plug/appliance, proceed as follows: 
The wire which is coloured Green & Yellow must be connected to the 
Earth terminal marked with the letter E or by the earth symbol or 
coloured Green or Green & Yellow. 
The wire which is coloured Blue must be connected to the terminal 
which is marked with the letter N or coloured Blue or Black. 
The wire which is coloured Brown must be connected to the terminal 
marked with the letter L or P or coloured Brown or Red. 
If in doubt, consult the instructions provided with the equipment or 
contact the supplier. 
This cable/appliance should be protected by a suitably rated and 
approved HBC mains fuse: refer to the rating information on the 
equipment and/or user instructions for details. As a guide, cable of 
0.75mm
2
should be protected by a 3A or 5A fuse. Larger conductors
would normally require 13A types, depending on the connection 
method used. 
Any moulded mains connector that requires removal /replacement 
must be destroyed by removal of any fuse & fuse carrier and disposed 
of immediately, as a plug with bared wires is hazardous if a engaged in 
live socket. Any re-wiring must be carried out in accordance with the 
information detailed on this label.
