E Series – E15 & E25 Operating Instructions 

 

 

 

 

 

 

IMPORTANT SAFETY INSTRUCTIONS 

 

 

CAUTION: RISK OF ELECTRIC SHOCK. 

DO NOT OPEN 

 

 

 
 

 

 
 
 

WARNING:  Apparatus with CLASS I construction shall be connected to a MAINS socket outlet with a protective 
earthing connection. 
 
WARNING:  To prevent injury, this apparatus must be securely attached to the rack in accordance with the 
installation instructions. 
 
Read these instructions. 
 
Keep these instructions. 
 
Heed all warnings. 
 
Follow all instructions. 
 
Do not use this apparatus near water. 
 
Clean only with a dry cloth. 
 
Do not block any ventilation openings, install in 
accordance with the manufacturer’s instructions. 
 
Do not install near any heat sources, such as 
radiators, heat registers, stoves or other apparatus 
(including amplifiers) that produce heat. 
 
Protect the power cord from being walked on or 
pinched particularly at plugs, convenience 
receptacles and the pint where they exit from the 
apparatus. 
 
The mains circuit breaker shall remain readily 
accessible. 
 
Only use attachments/accessories specified by the 
manufacturer. 
 
Use only with the cart, tripod, bracket or table 
specified by the manufacturer, or sold with the 
apparatus. When a cart is used, use caution when 
moving the cart/apparatus combination to avoid injury 
from a tip over. 
 
Disconnect this apparatus during lightning storms or 
when unused for a long period of time. 
 

 

Refer all servicing to qualified service personnel. 
Servicing is required when the

 

apparatus has been 

damaged in any way, such as if the power-supply cord or 
plug is damaged, liquid has been spilled or objects have 
fallen into the apparatus, the apparatus has been 
exposed to rain or moisture, does not operate normally, 
or has been dropped. 
 
Do not expose this equipment to dripping or splashing 
and ensure that no objects filled with liquids, such as 
vases, are placed on the equipment. 
 
To completely disconnect this equipment from the AC 
mains, disconnect the power cord from the mains circuit 
breaker. 
 
Where the amplifier is mounted in a rack and 
permanently connected to the mains, then the rack 
should be installed with a readily accessible connector 
or an ALL POLE circuit breaker with 3mm breaking 
distances. 
 
This unit is fitted with a 3-wire power cord. For safety 
reasons, THE EARTH LEAD SHOULD NOT BE 
DISCONNECTED IN ANY CIRCUMSTANCE. 
 
The cooling fans suck cool air in through the front and 
blow hot air out at the rear of the unit through the 
ventilating grills. The front and rear of the amplifier 
should have free exposure to the air (i.e. in a rack leave 
the front and rear doors off), with 2cm air gap at the 
sides and top. IF AIR IS NOT ALLOWED TO ESCAPE 
FROM THE REAR, OVER-HEATING WILL OCCUR. Take 
care when mounting other equipment in the same rack. 
 
The mains switch on the amplifiers only switches one 
pole of the mains supply, therefore for units with a 
detachable cord to be fully disconnected from the 
mains, the mains disconnect device (ie mains plug or 
mains coupler) should remain readily operable.  For 
units with a fixed mains lead the external all pole circuit 
breaker with 3mm breaking distances is the disconnect 
device and therefore the installation of the amplifier 
shall be carried out in accordance with all the applicable 
installation rules. 
 

 

The lightning flash with arrowhead 
symbol within an equilateral triangle is 
intended to alert the user to the presence 
if uninsulated “dangerous voltage” within 
the product’s enclosure that may be of 
sufficient magnitude to constitute a risk 
of electric shock to persons. 

The exclamation point within an 
equilateral triangle is intended to alert 
the user of important operating and 
maintenance (servicing) instructions in 
the literature accompanying the 
appliance.
