MECHANICAL INSTALLATION AND DIMENSIONS
•
When a battery is connected and the voltage level is above level
a
and less than level
b
, the CDR switch on and lets the voltage
through the terminals.
•
If the voltage rises above level
b
, the CDR switch off to protect
equipment or auxiliary battery.
•
When the voltage then drops below level
c
, the CDR switch on
again.
•
If the voltage drops below level
d
, the CDR switch off.

SAFETY FIRST
WARNING, risk of electric shock.
High output voltage. Do not touch uninsulated battery
terminals, connectors or other live electrical parts.
Disconnect the battery before maintenance, servicing or
dismantling.
Do not operate the unit if there is any evidence of damage.
Only qualified personnel should install, use or service this product.
Read and understand this instruction, the battery
instruction provided by your battery manufacture, and
your employer’s safety practice, before using, installing,
or servicing the product.
Operation status can be indicated by connecting a LED to the
battery isolator.
•
Install the battery isolator close to the batteries and use
appropriate cables to avoid unnecessary voltage drop.
•
Position the battery isolator so that the air supply is not
obstructed.
•
The battery isolator
should always be
securely fastened.
•
Protect supply cables
with suitable fuse/fuses.
•
Max torque = 18 Nm for
terminal T-1 and T-2.
•
Max torque = 10 Nm for
mounting screws.
•
Use the insulating caps
supplied.
