baltur BTG 3,6P, Instruction Manual

TO BE CARRIED OUT BY THE INSTALLER

• 

Install a suitable disconnecting switch for each burner supply line.

• 

The  disconnection  must  be  carried  out  by  means  of  a  device 

complying with the following requirements:

 -

A disconnecting switch - circuit breaker, according to IEC 60947-

3 for at least the equipment category AC-23 B (non-frequent 

operations on highly inductive loads or AC motors).

 -

A control and protection switching device suitable for isolation 

according to IEC 60947-6-2.

 -

A switch suitable for isolation according to IEC 60947-2.

• 

The disconnecting device must:

 -

Ensure the isolation of the electrical equipment from the power 

supply line when in the stable OFF position indicated with “0”, 

and be in a stable ON position indicated with “1”.

 -

Feature a visible gap between contacts or a position indicator 

that cannot indicate OFF (isolated) until all contacts are actually 

open and the requirements for the isolation function are met.

 -

Feature a grey or black actuator which can be easily identified.

 -

Be padlockable in the OFF position. In case of lock-out, remote 

and local activation will not be possible.

 -

Disconnect all the active conductors of its power supply 

circuit. For TN power supply systems, the neutral conductor 

can be disconnected or not, except in the countries where the 

disconnection of the neutral conductor (if used) is mandatory.

• 

Both disconnecting controls must be located at a height between 0,6 

m ÷ 1, 7 m with respect to the working plane.

• 

Since circuit breakers are not emergency devices, they can feature 

an additional cover or a door, which can be easily opened without 

any key or tool. Its function must be clearly indicated, e.g. with the 

relevant symbols.

• 

The burner can be installed only in TN or TT systems. It cannot be 

installed in isolated system of IT type.

• 

Do  not  reduce  the  section  of  the  conductors. A  maximum  short-

circuit current of 10kA is required at the connection point (before 

protection  devices)  in  order  to  ensure  the  correct  intervention  of 

protection devices.

• 

The automatic reset function on the thermal device which protects 

the  fan  motor  cannot  be  enabled  (by  irreversibly  removing  the 

relevant plastic label) for any reason.

• 

As  for  the  connection  of  cables  to  the  terminals  of  the  electrical 

equipment, make sure that the earth conductor length is such as to 

ensure that it is not subject in any way to accidental disconnection 

following any mechanical stress.

• 

Provide  for  a  suitable  emergency  stop  circuit  able  to  perform  a 

simultaneous stop in category 0 both on 230Vac single-phase line 

and on 400Vac three-phase line. The disconnection of both power 

supply lines ensures a “safe” transition in the shortest time possible.

• 

The emergency stop will have to be performed complying with the 

following requirements:

 -

The electrical emergency stop device must fulfil the “special 

requirements for control switches with direct opening” (refer to 

EN 60947-5-1: 2016, Attachment K).

 -

It is recommended that the emergency stop device is red and the 

surface behind it is yellow.

 -

The emergency action must be of the hold-to-run type and 

require a manual operation to be restored.

 -

When the emergency device is restored, the burner must not 

be able to start autonomously, but a further “run” action by the 

operator must be required.

 -

The emergency activation device must be clearly visible and 

easily reachable and actionable in the immediate vicinity of the 

burner. It must not be enclosed within protection systems or 

behind doors that can be opened with keys or tools.

• 

In the case that the burner is positioned in such a way that it cannot 

be  easily  reached,  activated  and  serviced,  provide  for  a  suitable 

service plane in order to ensure that the control panel is positioned 

between 0.4 ÷ 2.0 metres with respect to the service plane. This 

is to ensure an easy access by the operator for maintenance and 

adjustment operations.

• 

When  installing  the  input  power  and  control  cables  of  the  burner 

electrical equipment, remove the protection plugs and provide for 

suitable cable glands so that an “IP” protection degree equal to or 

higher than that indicated on the burner nameplate can be ensured.
