Section 7 - Electrical
Testing
WARNING
Ensure that you have fully read “Section 3 - Safety” before beginning
electrical testing.
This section contains guidelines for electrical testing of your
Mold-Masters
Hot Runner system. The testing is based on the following European and
North American standards:
•
EN 60204-1 / DIN EN 60204-1 (IEC 60204-1, modified) Safety of
machinery - electrical equipment of machines
• NFPA 79 Electrical Standard for Industrial Machinery
The standards themselves are the final authority for testing requirements
(also any additional testing requirements from any national standards where
the Hot Runner is in use).
7.1 Safety
WARNING
The user is responsible to ensure protection against shock by indirect
contact, by protective earth conductors and automatic disconnection of
supply. Mold-Masters components and systems are either equipped with a
protective earth conductor or there is a connector for this purpose.
Before you carry out electrical work, make sure that the Hot Runner system
is securely grounded. Turn the temperature control off and disconnect all
electric wires coming from the mold. Failure to follow any of these steps
may lead to serious injury or death.
Ensure that all wiring and connection work is performed by a qualified
electrician according to DIN EN 60204-1 / NFPA79.
If performing work on a disassembled nozzle, it should only be connected
to an electrical supply when the nozzle has been grounded or a safety
isolating transformer is used.
Contact with a disassembled, heated, nozzle would cause serious burns.
Use a sign in a visible location indicating “Danger: Do Not Touch”. Wear
protective heat-resistant gloves and a full face shield over safety glasses.
7.2 Electrical Wiring Check
1. Check that each wire and thermocouple has a zone number.
2. Check that wires are organized and taped together by zone and plug.
3. Check all wires are secured in wire channels.
4. Connect all power leads and thermocouple wires to mold plugs.
5. The electricity mains should only be connected to the injection mold when
all electrical connections are grounded and the mold is closed.
