5-10 Heratherm Thermo Scientific
• B 16 circuit breaker (3 x B16 for 3P units)
Connection to the power supply source
1. Before connecting the oven to the power source, check to see if the power supply voltage
corresponds with the specifications on the nameplate of the oven. If the voltage (V) and
current (A) ratings given are not as required, do not connect the device to the power
source!
2. Connect the IEC connector to the socket at the rear of the oven (not for 3P units).
3. Route the power cord along a path that does not cross exhaust air piping or passageways
and aisles. With stacked devices, keep the power cord away from hot spots on the other
oven in the stack.
4. Connect the protection-earthed plug of the power cord to a correctly protection-earthed
and earth leakage circuit breaker fused power socket.
5. Make sure the power cord is not subjected to tensile or compressive force.

Benefits of using separate electrical
feeders
Although several devices may be operated on the same electrical
feeder if the rated current is not exceeded, we strongly recommended
to provide one feeder with a dedicated upstream circuit breaker per
oven to avoid the failure of multiple devices in case of an electrical
fault.
Make sure that power outlets remain
freely accessible at all times!
In an emergency the power connection must be rapidly disconnectable;
so be sure to have the power outlets freely accessible at all times!
