System Installation and Wiring

The installation and wiring must be performed by a competent engineer. For permanently connected equip-
ment, a readily accessible disconnect device must be incorporated in the fixed wiring having contact separation
of at least 3 mm on each pole. The Galaxy 3 Series control panel must be connected to the a.c. mains supply
(230/240 Va.c. 50 Hz) via a fused connection outlet.
The fuse in the mains outlet must not exceed 3A.
WARNING: A means of isolation from the mains supply must be provided within 2 metres of
the control panel. Where live and neutral supplies can be identified, a fused spur
with a 3 amp fuse, must be fitted on the live circuit. Where live and neutral circuits
cannot be reliably identified, 3 amp fuses must be fitted to both circuits.
Route the mains cable through the hole on the right hand side of the enclosure base. Securely anchor the
cable to the box using the tie-wrap as shown in the following Figure:

base
Figure 2-6. Securing the Mains Cable to the Enclosure Base
Secure the panel base to the wall using three 1.5" No. 8 round head steel screws through the holes provided.
The mains cable used must be a three core type (with green/yellow earth insulation) of adequate current
carrying capacity.
NOTE: The mains cable must satisfy the requirements stated in BS6500.
Connect the mains cable to the mains terminal block as follows:
• blue wire to the terminal marked N (Neutral)
• green/yellow wire to the terminal marked (Earth)
• brown wire to the terminal marked L (Live)
NOTE: No other connections to the mains connector are permitted.
All wiring must be in accordance with the latest edition of the IEE Wiring Regulations, BS7671 (Requirements
for Electrical Installations).
