5.3 Electrical Connections –
Figs. 5.5 and 5.6
Warning. Before making
any connections, ensure that the
power supply, any powered control
circuits and high common mode
voltages are switched off.
Note. If it is not possible to
avoid strong electrical and
magnetic fields, screened cables
within earthed/grounded metal
conduit must be used.
5.4 Relays, Arc Suppression
and Outputs
5.4.1 Relay Contact Ratings
Relay contacts are rated at:
115/230V AC at 5A (non-inductive)
250V DC 25W max.
5.4.2 Arc Suppression - Fig. 5.5
Arc suppression components are fitted
to relays 2 and 3 only. If relay 1 is
required to switch inductive loads, the
arc suppression component supplied
must be fitted across the contacts
used.
