MultiLoad II/ RCU II Explosion Proof Lite (EXL) Installation Guide - Part # 6070

AC Powered Models

Provide over current protection using a 15 Amp circuit breaker or equivalent. The breaker also serves
as a means of disconnection from the operating supply as required by UL/ISA/IEC 61010-1 and
CAN/CSA-C22.2 NO. 61010-1. The disconnected device may not be blocked or be made difficult to
operate by the MultiLoad II/ RCU II or any other device. Note that installation of disconnects are
typically prohibited in Class I, Division 1 or Division 2 locations.

Power required: 85

– 250 Vac, 47 – 63 Hz, 300 mA @ 85Vac/ 150 mA @250Vac. The power

connector is located in the right hand, bottom corner of the Power Supply/Communication board as
shown in figure 3.3. Select supply wire rated 300V or better with a flammability rating of at least VW-1.
