4.6 CONNECTIONS
WARNING
Let installation work be done by a licensed
electrician. Before connecting the wiring,
make the AC distribution as well as the DC
distribution voltage free.
CAUTION!
Short circuiting or reversing polarity may
seriously damage the batteries, the
Chargemaster, the cabling and/or the terminal
connections. Fuses between the batteries and
the Chargemaster can not prevent damage
caused by reversed polarity. Reverse polarity
damage is detectable by the service
department and not covered by the warranty.
CAUTION!
Too-thin cables and/or loose connections can
cause dangerous overheating of the cables
and/or terminals. Therefore tighten all
connections well, in order to limit transition
resistance as far as possible. Use cables of
the correct size.
NOTE:
If the battery temperature remains within 15-
25°C, connection of the battery temperature
sensor is an option.
