3.4 Electrical Installation
A fully qualified electrical engineer must undertake all field wiring and electrical work in accordance with local regulations.
3.4.1 BAM Electrical Supply
The module should be connected to a single phase electrical supply through
a switch or circuit breaker.
This device should be:
• Suitable for the application and selected in accordance with local and
national code regulations.
• Clearly and indelibly marked as the disconnecting device for the
equipment.
• Located in close proximity to the equipment and be easily accessible
to the operator.
Note. The disconnection device must be locked in the 'OFF' position
during installation.
Overcurrent protection must be fitted as part of the building installation. This
protection should be selected in accordance with local and national code
regulations.
Feed the supply cable through the spare cable gland and connect it to the
electrical supply terminal block. Each wire should be terminated using
suitable ferrules. Secure the cable gland to protect the terminations.
3.4.2 BAM Remote alarm indication
The module is fitted with a set of volt free relay contacts (1A max @ 250Vac
/ 30Vdc) designed for remote alarm indication.
Connection should be made to the Remote alarm terminal block.
O/N
Normally open contacts
Comm
Common terminal
N/C
Normally closed contact
The cable used should be 0.75mm
that it is routed away from high voltage cables.
Note. The relay is energised when the module is operating under normal
conditions.
If the remote alarm indication relay is used, the electrical enclosure will contain more than one live circuit. The relay
connections will remain live when the mains supply is disconnected.
