Two cables are required per sensor. The RG178 should be used where the cable itself is subject
to temperatures exceeding 74 °C.
Note
Protection for permanently installed equipment:
This equipment is regarded as permanently installed equipment and must be wired up using
suitable cable for the current and voltage specified. A suitable switch or circuit breaker must be
included in the installation and this should be in close proximity to the equipment and marked
as its disconnecting device. A suitable fuse rated at 3 A must be fitted in the supply. Each relay
circuit must be protected by a fuse not exceeding the maximum rated current for the relay as
specified in the manual. As S/C current on the transformer secondary is in the order of 70 mA
and the transformer thermal fuse will not operate for at least 17 minutes (as tested), a smaller
value mains fuse (63 mA) should be agreed upon.
