Mounting the Compact unit
The Compact unit weighs 4Kgs with batteries, so care should be taken to securely mount the unit on stud walling.
Connecting the Compact unit
To comply with EMC (Electro Magnetic Compatibility) regulations and to reduce the risk of electrical interference in the system
wiring, we recommend the use of fire-resistant screened cables throughout the installation.
All wiring should come into the enclosure via the knockouts provided, and be fixed tidily to the relevant terminals.
Note that correct cable glanding is essential and due regard should be paid to any system specifications which demand a certain
cable type (providing it meets the appropriate national wiring regulations).
Planning the Wiring
All system wiring should be installed to meet the appropriate parts of BS5839-9 (2011) and BS 7671 (Wiring Regulations). Other
national standards of installation should be adhered to where applicable.
Do not test wiring with an insulation tester (Megger) with any equipment or outstations connected, as the 500 Volt test voltage will
destroy these devices totally.
You must observe local wiring regulations. Do not run SELV and LV cables in the same enclosure without adequate insulation
between them.
Mains Connection
Each compact requires a 3A spur, returning to a breaker clearly marked “
EVCS DO NOT TURN OFF”
. If the units are distributed
around a site it is essential all units are on the same mains phase, as they are classified TEN 230V, powering from different phases
can mean a 440V potential can be present in a unit during a major fault incident.
