uring installation and commissioning of the
Chargemaster, the important safety instructions are
applicable at all times. See chapter 2 of this manual.
4.1 UNPACKING
In addition to the Chargemaster the delivery includes:
• A mounting bracket to mount the chargemaster to a
wall;
• a battery temperature sensor;
• a MasterBus terminating device (see chapter 6);
• a cable gland for UL-compliant AC-connection (see
section 4.4);
• this user’s manual.
After unpacking, check the contents for possible damage.
If in doubt, contact your supplier.
Check from the identification label (see section 1.4)
whether the battery voltage is the same as the nominal
output voltage of the Chargemaster (e.g. 24V battery set
for a 24V battery charger).
4.2 ENVIRONMENT
Obey the following stipulations during installation:
• The Chargemaster is designed for indoor use only.
• Ambient temperature: 0 ... 60°C / 32°F … 140°F;
(power derating above 40°C / 104°F to decrease the
internal heat sink temperature).
• Humidity: 0-95% non condensing
• Mount the Chargemaster vertically, with the connecting
cables downwards.
• Make sure that the hot air that is developed during
operation can be discharged. The Chargemaster must
be mounted in such a way that obstruction of the
airflow through the ventilation openings will be
prevented.
• No objects must be located within a distance of 10 cm /
4 inch around the Chargemaster.
• Do not locate the Chargemaster in the same
compartment as the batteries.
• Do not install the Chargemaster straight above the
batteries because of possible corrosive sulphur fumes.
4.3 WIRING
WARNING!
The wire and fuse sizes stated in this manual
are given as example only. Prescribed wire
and fuse sizes may be different due to local

4.3.1 AC-wiring
For a safe installation the correct wire cross section must
be applied. Don’t use a cross section that is smaller than
indicated. See table below to select the appropriate cross
section for the AC wiring (up to 6m / 20ft length):
AC-Current Minimum cross section:
in mm² AWG
6-12 Amp 1.5 mm² AWG 15
12-20 Amp 2.5 mm² AWG 13
