Wiring power supply
WARNING
Use wiring cables with heat resistance above 75°C.
For power supply, wire cables with a flammability rating of UL 2556 VW-1 or equivalent.
CAUTION
Turn off power supply to PG400 before wiring. Power rating must comply with PG400
specification. Power voltage must match with the one indicated on the name plate.
WARNING
●
You must install external power supply switch or circuit breaker for power supply.
●
The external power supply switch or a circuit breaker must comply with a current rating of
5A, IEC60947-1 or IEC60947-3.
●
Yokogawa recommend installing the external power supply switch, circuit breaker and
PG400 all in the same location.
●
Install the external power supply switch or circuit breaker to the place where operators
access easily. To alert users, put a label on the external power switch.
●
Wire cables of power supply or contact output securely with cable rack, conduit and vinyl
band. Unplugged cables are dangerous and may cause an electric shock.
Some regions where the instrument is used may require the installation of an external circuit
breaker.
When TB810D or TB820 supplies power, no installation of an external circuit breaker is needed.
To prepare for wiring cables, open the front cover and remove the protect cover so that you can
access terminals easily.
The size of power supply cable is 2.0 mm
2
(14 AWG) or larger. Use the crimp terminals of 7.2 mm
or less width. The terminals use M4 screw.
