DANGER
Electrical Shock Hazard
Disconnect electric before service.
Heater must be properly grounded.
Failure to follow these instructions can result
in death or electrical shock.
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 37 , Section 11.1 through
Page 38, Section 11.3 for the external wiring details for
the single-burner and double linear heaters.
If the IP55 protected fan MB 56 2BM is used with a single
burner (linear), it must be wired as shown on Page 38,
Section 11.2.
The fan must be protected with a 3 A fuse.
If the heater lockout indication is required, a
BLACKHEAT ® AG volt free package (P/N 03360008)
must be installed in every burner. Drill a 20.5 mm hole to
fit the wire gland. See Page 39, Section 11.4 for wire
connections. Remove the taps from the power wire.
