ELECTRICAL SAFETY
To reduce the risk of fire, connect only to a circuit
provided with a 7A / 10A maximum branch circuit
overcurrent protection in accordance with BS1362.
Do not work alone under hazardous conditions.
Check that the power cord(s), plug(s), and sockets
are in good condition.
To reduce the risk of electric shock, disconnect
the equipment from the AC power outlet before
installing or connecting to other equipment.
Reconnect after all electrical connections are made.
Use one hand, whenever possible, to connect or
disconnect signal cables to avoid a possible shock
from touching two surfaces with different
electrical grounds.
Connect the equipment to a three wire AC connection
(live, neutral and ground). The unit must be connected
to appropriate branch circuit/mains protection
(fuse or circuit breaker). Connection to any other
type of connection may result in a shock hazard.
In order to maintain compliance with the EMC
directive, wires attached to the Powervault
should not exceed 25 meters in length.
• Prepare the electrical wiring according to figure 1 or figure 2. All wiring to be perform in strict accordance with
local building regulations.
• The ideal installation will feature a separate RCBO block splitting from the Henley Block as shown in figure 1.
• If this is not possible connecting to consumer unit is acceptable as long as it is on a dedicated 16A RCBO can be
inserted into the unit as shown in figure 2.
• The rotary isolator will need to be installed directly downstream of the dedicated RCBO.
• If a power socket needs to be added for the Powervault internet connection then the additional power socket
should be installed downstream of the rotary isolator as shown in figure 1.
• The fused spur should be rated according to table 1.
