SECTION 13: WIRING
Connect to the electrical supply using the power wire 
coming out of the wire gland via a locally mounted IP55 
protected double pole fused switch having a minimum 
disconnection of 3 mm on each pole. This switch should 
be fused to 3 amps. There are no control connections in 
the standard burner. Control is affected by interruption of 
the main power inlet. See Page 54, Section 13.1 through 
Page 55, Section 13.4
 
for the external wiring details for 
the single-burner, double linear and multiburner heater 
systems.
If the IP55 protected fan MB 56 2BM is used with a single 
burner (linear or U-tube), it must be wired as shown on 
Page 55, Section 13.2
.
The fan must be protected with a 3 A fuse.
If the heater lockout indication is required, a 
BLACKHEAT® HE lockout indicator package (P/N 
03360008) must be installed in every burner. Drill a 20.5 
mm hole to fit the wire gland. See Page 56, Section 13.5 
for wire connections. Remove the taps from the power 
wire.
All wiring must comply with current wiring regulations and 
any local regulations which may apply. Always switch off 
the supply to the burner before removing the burner side 
panel.
